MOSFET PCB for the Adafruit HUZZAH32 (ESP32 Feather)

This PCB provides control of eight MOSFET outputs. These can be controlled through an Adafruit Feather HUZZAH32 microcontroller. It is a two-layer PCB and all parts can be handsoldered in case that costs are a concern.

This board was designed using KiCad 6.0.

MOSFEaTher: common questions

What microcontroller does the MOSFEaTher use?

The MOSFEaTher is built around the 3.3V (ESP32), from the ESP32 family.

How big is the MOSFEaTher PCB?

The MOSFEaTher measures 63.5 × 51.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MOSFEaTher?

30 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the MOSFEaTher design files?

From the MartinWeigel/MOSFEaTher repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MOSFEaTher design in my own project?

The repository has no license, so all rights stay with MartinWeigel. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MOSFEaTher without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
