    1Bitsy 1UP

    1Bitsy 1UP is a retro inspired handheld game console, the design is based on the 1Bitsy STM32F415RGT6 ARM Cortex-M4F 168MHz 192kb RAM and 1MB Flash micro controller. 2.8″ TFT with capacitive touch, SDCard Reader and a few other components.

    The display used is a TFT LCD with I2C CapTouch and ILI9341 driver. (should be compatible with the display sold by Adafruit on their breakouts as well as the buydisplay.com 2.8″ tft with CapTouch sensor)
