The Adafruit PiOLED is your little OLED pal, ready to snap onto any and all Raspberry Pi computers, to give you a little display. The PiOLED comes with a monochrome 128x32 OLED, with sharp white pixels. The OLED uses only the I2C pins so you have plenty of GPIO connections available for buttons, LEDs, sensors, etc. It's also nice and compact so it will fit into any case.

Incorporating Bluetooth in a project no longer requires the most advanced microcontroller or lots of code…our Bluefruit LE UART Friend and accompanying app for iOS and Android make it easy! Building upon our popular "Kaleidoscope Eyes" NeoPixel goggles project, this guide shows how Bluetooth LE can be used even with the most modest setup.
We carry a few different GPS modules here in the Adafruit shop, but none that satisfied our every desire - that's why we designed this little GPS breakout board.
