•2.2" diagonal true TFT LCD display has 320x 240 colour pixels• The TFT driver can display full 18-bit colour (262, 144 shades!)• Ultra-low-dropout 3.3V regulator & a 3/5V level shifter so you can use it with 3.3V or 5V power & logic• Comes with a micro SD card holder so you can easily load full colour bitmaps from a FAT16/FAT32 formatted micro SD card• Please click here for the detailed graphics library This lovely little display breakout is the best way to add a small, colourful & bright display to any project. Since the display uses 4-wire SPI to communicate & has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory & few pins available! The 2.2" display has 320x 240 colour pixels. Unlike the low cost " Nokia 6110" & similar LCD displays, which are CSTN type & thus have poor colour & slow refresh, this display is a true TFT! The TFT driver (ILI9340) can display full 18-bit colour (262, 144 shades!). & the LCD will always come with the same driver chip so there's no worries that your code will not work from one to the other. The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator & a 3/5V level shifter so you can use it with 3.3V or 5V power & logic. We also had a little space so we placed a micro SD card holder so you can easily load full colour bitmaps from a FAT16/FAT32 formatted micro SD card. ...

•4 BSS138 FETs with 10K pullups• Works down to 1.8V on the low side, up to 10V on the high side• Designed for I2C, but also works for SPI, TTL Serial, & any other digital interface both uni-directional & bidirectional• Comes with a fully assembled & tested PCB•4 full bidirectional converter lines as well as 2 pieces of 6-pin header you can solder on to plug into a breadboard or perfboard• Click here to check out the BSS138 Datasheet• Click here to see the NXP App note explaining how it works Because the Arduino (and Basic Stamp) are 5V devices, & most modern sensors, displays, flash cards & modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V. This level shifter board combines the ease-of-use of the bi-directional TXB0108 with an I2C-compatible FET design following NXP's app note. ...

•CAP188 has support for both I2C & SPI, so it easy to use with any microcontroller• If using I2C, you can select one of 5 addresses, for a total of 40 capacitive touch pads on one I2C 2-wire bus• Using this chip is a lot easier than doing the capacitive sensing with analog inputs: it handles all the filtering for you & can be configured for more/less sensitivity Add lots of touch sensors to your next microcontroller project with this easy-to-use 8-channel capacitive touch sensor breakout board, starring the CAP1188. This chip can handle up to 8 individual touch pads, & has a very nice feature that makes it stand out for us: it will light up the 8 onboard LEDs when the matching touch sensor fires to help you debug your sensor setup.CAP188 has support for both I2C & SPI, so it easy to use with any microcontroller.

Comes with a fully assembled board, & a stick of 0.1"" header so you can plug it into a breadboard. For contacts, we suggest using copper foil, then solder a wire that connects from the foil pad to the breakout. Getting started is a breeze with the Adafruit Arduino library & tutorial. You'll be up & running in a few minutes, & if you are using another microcontroller, its easy to port the code. The CAP1188 datasheet can be found here ...

• Built in clock which can multiplex the display• Constant-current drivers for ultra-bright, consistent colour•1/16 step display dimming• All via a simple I2C interface• The backpack comes with address-selection jumpers so you can connect up to eight of these bar-graphs on a single I2C bus• You can also mix-&-match the bar-graph breakout with our other types of I2C LED backpacks• And to view the library please click here to help you get started!• To see Adafruits tutorial showing how to solder, wire & control the display please click here What's better than a single LED? Lots of LEDs! A fun way to make a small linear display is to use two 12-bar Bi-colour bar-graphs. However, this LED bargraph is 'multiplexed'
- so to control all the 48 LEDs you need a lot of pins. There are driver chips like the MAX7219 that can help control a bar-graph/matrix for you but there's a lot of wiring to set up & they take up a ton of space. Much like our 8x 8 & 7-segment backpacks, this backpack pairs perfectly with our bar-graphs & manages all the LED control & multiplexing. The backpack uses a driver chip that does all the heavy lifting for you: It has a built in clock so it can multiplex the display. It uses constant-current drivers for ultra-bright, consistent colour, 1/16 step display dimming, all via a simple I2C interface. The backpack comes with address-selection jumpers so you can connect up to eight of these bar-graphs on a single I2C bus. You can also mix-&-match the bar-graph breakout with our other types of I2C LED backpacks.

• Measures temperature via the subjects emitted IR waves• An embedded thermopile sensor generates a (small) voltage dependant on IR levels, which can be used to measure temperature• Measurement taken over an area so can be used to work out average temperatures• Works with 3 to 5V logic
- no logic level shifting needed•
Includes: a small piece of 0.1"" breakaway header so you can easily solder to & use this sensor on a breadboard•i 2c compatible interface•20mm long by 20mm wide Unlike all the other temperature sensors we have, this breakout has a really cool IR sensor from TI that can measure the temperature of an object without touching it! Simply point the sensor towards what you want to measure & it will detect the temperature by absorbing IR waves emitted. The embedded thermopile sensor generates a very very small voltage depending on how much IR there is, & using some math, that micro voltage can be used to calculate the temperature. It also takes the measurement over an area so it can be handy for determining the average temperature of something. This sensor comes as a ultra-small 0.5mm pitch BGA, too hard to solder by h&. So we stuck it on an easy-to-work-with breakout board. The sensor works with 3 to 5V logic so it requires no logic level shifting. There are two address pins & using a funky method of connecting the pins you can have up to 8 TMP006's connected to one i 2c bus (see the datasheet table 1 for the connections). We also include a small piece of 0.1" breakaway header so you can easily solder to & use this sensor on a breadboard. Two mounting holes make it easy to attach to an enclosure. Of course, we wouldn't just hand you a datasheet & wish you luck, theres an easy-to-use Arduino library with an example that will have you up & running in 5 minutes. The code can also be ported to any microcontroller with i 2c support, the hardest math part has already been taken care of. The nice folks at Adafruit have even knocked up an Arduino library click here. Wanting more information clock here to see the datasheet. And the easy to use user guide can be found here.
