M4-Shim
ARM Cortex M4 shim for PoE-FeatherWing, functionally equivalent to Feather M4 Express
You can buy it now on Tindie or on Amazon!
Description
This is an adaptation of the excellent Adafruit Feather M4 Express, redesigned specifically for use with the equally excellent PoE-FeatherWing.
The goal was to create a compact system with Power over Ethernet, Ethernet connectivity and a powerful processor capable of supporting CircuitPython. Because of the bulky RJ45 jack and flyback transformer on the PoE-FeatherWing, it was not possible to mount a traditional Feather on top. This redesign takes the relevant circuitry of the Adafruit Feather M4 Express and shapes it so it fits in the gaps between the tall components of the PoE-FeatherWing. This way it can be mounted on top for an extremely compact solution.
The only thing missing versus the Feather M4 Express is the battery support circuitry, which did not seem necessary in a PoE design.
The hardware is sold with the UF2 bootloader and CircuitPython pre-installed.
