GPIO, Analog, SPI, I2C, UART... just plug in anything!
It runs on the ATSAMD21 microcontroller, a 32-bit Arm Cortex M0+ clocked at 48Mhz, as found on many popular Arduino-compatible boards.
Though FIDI only features 6 GPIOs, they can be configured as digital or analogue IOs, SPI, I2C, UART, or a combination thereof. Four of those GPIOs are available through terminal block connectors, allowing connections with a simple screwdriver. The two remaining GPIOs are available on a four-pin JST-SH connector, in an arrangement that is fully compatible with Adafruit's STEMMA system. This allows you to quickly test sensors and other circuits without any soldering.
Thanks to CircuitPython, writing code for FIDI is super simple. Once connected to a computer with a simple USB micro connector, FIDI shows up as a USB drive where you can drag-and-drop or edit your python code.
