•A 320x 240 2.8"" 16-bit display to enhance your Pi based projects• Resistive touch interface• Driven via hardware SPI interface to display a variety of images & outputs•GPIO breakout pins to work with Pi boards• Please click here to view the detailed guide & drivers Is this not the cutest little display for the Raspberry Pi? It features a 2.8" display with 320x 240 16-bit colour pixels & a resistive touch overlay. The plate uses the high speed SPI interface on the Pi & can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top! Uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO 25 & 24. All other GPIO are unused. Since we had a tiny bit of space, there's 4 spots for optional slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button. See below for the link to get the optional tact switches, they're not included. This version comes as a mini-kit, with a 2x 13 extra-tall female header (to connect the plate to the Pi) & a 2x 13 male header that can be used to connect an IDC cable or cobbler from the side. ...

• Great for powering your robot, Arduino project, single-board-computer such as Raspberry Pi or Beagle Bone!• Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground•2A internal switch means you can get 500m A+ from as low as 1.8V, 750m A+ from 2 Ni MH or Alkaline batteries• And at least 1000m A from a 3.7V Li Poly/ Li Ion battery or 3 Ni MH/ Alkalines• Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for the most common usage of Li Po/ Li Ion battery usage• On-board 500m A charge-rate ' Apple/i OS' data resistors. Solder in the included USB (Universal Serial Bus) connector & you can plug in any iPhone or iPod for 500m A charge rate• Not suggested for iPad• Full breakout for battery in, control pins & power out•90%+ operating efficiency in most cases (see datasheet for efficiency graphs)• Low quiescent current: 5m A when enabled & power LED is on, 20u A when disabled (power & low batt LED are off) Power Boost is the perfect power supply for your portable project! This little DC/DC boost converter module can run from 1.8V batteries or higher, & convert that voltage to 5.2V DC for running your 5V projects. The output is tweaked to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB (Universal Serial Bus) cable resistance. The Power Boost 500 has at the heart a TPS61090 boost converter from TI. This boost converter chip has some really nice extras such as low battery detection, 2A internal switch, synchronous conversion, excellent efficiency, & 700 K Hz high-frequency operation. Check out these specs! Each order comes with one fully assembled & tested PCB & a loose USB (Universal Serial Bus) A jack. If you are powering your project from USB (Universal Serial Bus), solder the USB (Universal Serial Bus) A jack in (a 3-minute soldering task). If you would like to use a terminal block, you'll need to pick up a 3.5mm 2pin block & solder to the output spot where the USB (Universal Serial Bus) jack would go. Or don't solder anything in for a more compact power pack. ...

- the Pro Trinket! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega 328. It's like an Arduino Pro Mini with more pins & USB (Universal Serial Bus) tossed in. Trinket's a year old now, & while its been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, & more RAM. That's why Adafruit designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, & 2K of RAM. Like the Trinket, it has onboard USB (Universal Serial Bus) bootloading support
- Adafruit opted for a Micro USB jack this time. Adafruit also added Optiboot support, so you can either program your Pro Trinket over USB (Universal Serial Bus) or with a FTDI cable just like the Pro Mini & friends. The Pro Trinket PCB measures only 1.5"" x 0.7"" x 0.2"" (without headers) but packs the same capability as an Arduino UNO. So it's great once you've finished up a prototype on an official Arduino UNO & want to make the project smaller. The Pro Trinket uses the Atmega 328P chip, which is the same core chip in the Arduino UNO/ Duemilanove/ Mini/etc. However, the 3V version uses 3V logic & 12 M Hz clock which means it's good when you want a lower-power & lower-voltage setup. Pro Trinket is programmable using the Arduino IDE as you already set up, & 95% of Arduino projects will work out of the box! For tons more details, check out the Introducing Pro Trinket tutorial or the Datasheet Here's some things you may have to consider when adapting Arduino sketches: Pins 2 & 7 are not available (they are exclusively for USB) The Pro Trinket 3V runs at 12 M Hz, this doesn't affect most projects. Only the most timing-specific libraries may be affected, check the documentation! The Neo Pixel Library works fine at 12 M Hz. The onboard power supply is a 3.3V regulator & it can provide 150m A output You cannot plug shields directly into the Pro Trinket There is no Serial-to-USB chip onboard. This is to keep the Pro Trinket small & inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection. The USB (Universal Serial Bus) connection is for uploading new code only. The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28, 672 bytes.

• Easy set up: connect power source to Ground & IN, then the load from Ground to OUT• Uses a 3A P-FET to connect & disconnect IN pin to OUT pin• Works from 3V to 14V DC & up to 3A•
Includes: a 12mm tactile switch but you can solder in your own if needed•0.5u A quiescent current draw• On-board red LED lights up when active• Fourth KILL pin will turn off the FET when 1 or more volts is applied, can be used to allow your project to turn itself off! The Adafruit Push-button Power Switch is a tidy little design that lets you control a DC power source using an everyday tactile button. The breakout uses a latching analog circuit that is triggered by a push of the button. Press once to turn on, then press again to turn off. The circuit uses a 3A P-FET to connect & disconnect the IN pin to the OUT pin. Works great from 3V to 14VDC & up to 3A (although the FET gets a little toasty at continuous 3A draw) yet has only 0.5u A quiescent current draw. Using it is easy: connect the power source to Ground & IN, then the load from Ground to OUT. We include a 12mm tactile switch that works well but you can solder in your own switch as well. Press the button (or short the button pins) to alternate between on or off. A on-board red LED will light up when active so you know its working. There's a fourth KILL pin, which you can use to turn off the load and/or keep it off even if the button is pressed. When 1 or more volts is applied it will instantly turn off the FET. This allows your project to turn itself off. Comes with a assembled & tested bread-board friendly breakout board with four mounting holes, a 12mm tactile button, & some 0.1" male header you can solder to the board to plug it into a breadboard. The power switch is an elegant way to control power to your project, but there are some things to keep in mind: since there is a pass FET, this is only for 3-14V DC voltages. This is not a mechanical switch so there is no air-gap isolation. There is a 'body diode' in the pass FET so if the load has a voltage on it that is higher than the input voltage, current will flow back to the input. There is built-in debouncing but very bouncy switches can be annoying as they will turn on & off fast instead of latching.

•16x 2 Character LCD• Available in both positive & negative versions (for positive version see Maplin order code A66QN)•RGB backlight•5 buttons (4-way direction pad, & one select) provide programmable inputs • Contrast control• Extra-tall 26-pin GPIO header so the plate sits above USB (Universal Serial Bus) & Ethernet jacks• Uses only two pins (I2C) on the Raspberry Pi GPIO leaving the rest available for your own Maplin Project!• Can be used with other I2C bus devices• For a detailed tutorial guide please click here This new Adafruit Pi Plate makes it easy to use an RGB 16x 2 Character LCD. We really like the RGB Character LCDs we stock in the shop. (For RGB we have RGB negative & RGB positive.) Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD & then another 3 to control the RGB backlight for a total of 9 pins. That's nearly all the GPIO available on a Pi! With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a Pi plate that lets you control a 16x 2 Character LCD, up to 3 backlight pins & 5 keypad pins using only the two I2C pins on the R-Pi! The best part is you don't really lose those two pins either, since you can stick i 2c-based sensors, RTCs, etc & have them share the I2C bus. This is a super slick way to add a display without all the wiring hassle. This Pi plate is perfect for when you want to build a st&-alone project with its own user interface. The 4 directional buttons plus select button allows basic control without having to attach a bulky computer. The plate is designed for both Revision 1 & Revision 2 Raspberry Pi's. It uses the I2C (SDA/SCL) pins. We have a special xtra-tall 26-pin header so the plate sits above the USB (Universal Serial Bus) & Ethernet jacks. This product comes as a kit! Included is a high quality PCB & all the components (buttons, header etc). A 16x 2 Character RGB positive LCD is included! Assembly is easy, even if you've never soldered before & the kit can be completed in 30 minutes. ...

•RGB & Clear light sensing elements•IR blocking filter, integrated on-chip & localised to the colour sensing photodiodes allows for more accurate measurements•3, 800, 000:1 dynamic range with adjustable time & gain so suitable for use behind darkened glass•3.3V regulator so you can power with 3-5VDC safely• Level shifting for i 2c pins means you can use 3.3V or 5V logic• Neutral 4150K temperature LED with MOSFET driver onboard to illuminate what you'r trying to sense (can be turned on or off using any logic level output•20.44mm by 20.28mm Your electronics can now see in dazzling colour with this lovely colour light sensor. We found the best colour sensor on the market, the TCS34725, which has RGB & Clear light sensing elements. An IR blocking filter, integrated on-chip & localized to the colour sensing photodiodes, minimizes the IR spectral component of the incoming light & allows colour measurements to be made accurately. The filter means you'll get much truer colour than most sensors, since humans don't see IR. The sensor also has an incredible 3, 800, 000:1 dynamic range with adjustable integration time & gain so it is suited for use behind darkened glass. We add supporting circuitry as well, such as a 3.3V regulator so you can power the breakout with 3-5VDC safely & level shifting for the I2C pins so they can be used with 3.3V or 5V logic. Finally, we specified a nice neutral 4150°K temperature LED with a MOSFET driver onboard to illuminate what you're trying to sense. The LED can be easily turned on or off by any logic level output. Connect to any microcontroller with I2C & our example code will quickly get you going with 4 channel readings. We include some example code to detect light lux & temperature that we snagged from the eval board software. A detailed tutorial can be found by clicking here Click here to check out our Arduino library & follow our tutorial to install Wire up the sensor by connecting VDD to 3-5VDC, Ground to common ground, SCL to I2C Clock & SDA to I2C Data on your Arduino.
