About the Adafruit ESP32 Feather V2 PCB

Adafruit ESP32 Feather V2 is an open source ESP32 PCB design by iffycodes, published on GitHub. It is a 2-layer board measuring 50.8 × 22.9 mm, with 51 components from 33 distinct parts.

Its main chip is the CP2102N-24, from the ESP32 family. Other key parts include the 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 dev boards & breakouts and power & battery designs in this gallery.

From the project

Genesis Board design

- Removed Stemma QT connectors. Left second LDO (AP2112-3.3). It looks to only be powering the neopixel on GPIO0. Need to figure out if I can just use the main one. - Removed voltage divider used for LiPo monitoring. Provided A13_I35 that went to I35 on the ESP. - Removed LiPo charging circuit. VBUS is now only supplied by USB-C connector. Removed DMG3415U transistor in upper left of Page 2. Removed JST battery connector. - Removed extra reset switches. - Add initial annotation. - Rename +3V3 net on RTC page to match 3.3V global net name. - Rename MISO nets on Ethernet page so global MISO net…

Adafruit ESP32 Feather V2: common questions

What microcontroller does the Adafruit ESP32 Feather V2 use?

The Adafruit ESP32 Feather V2 is built around the CP2102N-24, from the ESP32 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 iffycodes/Genesis 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?

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

Can I test firmware for the Adafruit ESP32 Feather V2 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.
