#Minitube raspberry pi plus#
The Femto board is open-source hardware with the KiCAD and Altium design files (schematics, PCB layout) plus manufacturing files, the bill-of-materials, etc… available on Github where you’ll also find a Python script to tet all 30 GPIOs, as well as some extra photos. It comes with LEDs to test the GPIOs, a USB Type-C port for power and programming, as well as the BOOTSEL and Reset buttons.
The board is comprised of two parts: the module itself (aka mainboard) with the Raspberry Pi RP2040 microcontroller and the frame (aka solder frame) exposing the I/Os in a somewhat usable way.īut since the Femto is so small, Mirek also designed a tester to test the module. Misc – Status LED, 12MHz crystal oscillator, decoupling capacitors.I/O – 30 GPIO pins, Reset and BOOTSEL signals, etc… exposed through a frame (See below).MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller up to 133Mhz with 264kB of SRAM.We’ve previously covered some really tiny RP2040 boards with the Pimoroni Tiny 2040 and Adafruit QT Py RP2040 boards, as well as the RP2040 Stamp module, but the 12x12mm Femto module is about a quarter of the size of 25x25mm RP2040 Stamp. Mirek Folejewski has designed the ridiculously tiny Femto module based on the Raspberry Pi RP2040 microcontroller with a size of just 12x12mm, and still including an SPI flash, a crystal, and a few passive components.
