What you need is an add on prototyping Pi Plate from Adafruit, which can snap onto the Pi PCB (and is removable later if you wish) & gives you all sorts of prototyping goodness to make building on top of the Pi super easy. We added lots of basic but essential goodies. First up, there's a big prototyping area, half of which is 'breadboard' style & half of which is 'perfboard' style so you can wire up DIP chips, sensors, & the like. Along the edges of the proto area, all the GPIO/I2C/SPI & power pins are broken out to 0.1" stips so you can easily connect to them. On the edges of the prototyping area, all of the breakout pins are also connected to labeled 3.5mm screw-terminal blocks. This makes it easy to semi-permanently wire in sensors, LEDs, etc. There's also a 4-block terminal block broken out to 0.1" pads for general non-GPIO wiring. Finally, we had a little space remaining over the metal connectors so we put in an SOIC surface mount chip breakout area, for those chips that dont come in DIP format. Kit

• 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.
