About the Adafruit ESP32 Feather V2 PCB

Adafruit ESP32 Feather V2 is an open source RP2040/RP2350 PCB design by cgallizzi, published on GitHub under the MIT license. It is a 2-layer board measuring 50.8 × 22.9 mm, with 51 components from 33 distinct parts.

Its main chip is the ESP32-PICO-MINI-02MINI, from the RP2040/RP2350 family. Other key parts include the CP2102N-24, AP2112-3.3 and MCP73831T-2ACI/OT. By type, the board carries 13 capacitors, 11 resistors, 9 ICs, 4 diodes, 3 crystals and 2 transistors.

It belongs with the displays & leds and dev boards & breakouts designs in this gallery.

From the project

Steam Machine e-ink faceplate with a Now Playing mode: box art, playtime, achievements. Fork of Valve's Inkterface.

An e-ink faceplate for your Steam Machine that shows the box art, playtime, and achievement progress of whatever you're playing — plus all the original system telemetry readouts.

Now Playing artwork mode: when you launch a game, the panel switches to that game's box art with your total playtime and achievement progress rendered next to it (dithered for the e-ink look). When you quit, it goes back to the regular telemetry layout. Toggle it with the Box Art button in the configure screen. Game collectors: Game Time and Achievements readouts you can put in any panel field, alongside the stock…

Adafruit ESP32 Feather V2: common questions

What microcontroller does the Adafruit ESP32 Feather V2 use?

The Adafruit ESP32 Feather V2 is built around the ESP32-PICO-MINI-02MINI, from the RP2040/RP2350 family.

How big is the Adafruit ESP32 Feather V2 PCB?

The Adafruit ESP32 Feather V2 measures 50.8 × 22.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Adafruit ESP32 Feather V2?

51 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Adafruit ESP32 Feather V2 design files?

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

Can I use the Adafruit ESP32 Feather V2 design in my own project?
