About the ESP32-Feather-6B6L PCB

ESP32-Feather-6B6L is an open source ESP32 PCB design by RobertPHeller, published on GitHub under the CC-BY-4.0 license. It is a 2-layer board measuring 86.4 × 78.7 mm, with 36 components from 17 distinct parts.

Its main chip is the TCAN332DR, from the ESP32 family. Other key parts include the LM2574N-5.0, 74HCT14 and TBD62084A. By type, the board carries 14 resistors, 11 capacitors, 4 ICs, 4 connectors, 1 diode and 1 inductor.

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

From the project

ESP32 based LCC Boards

This is a collection of Model Railroad open hardware and open source projects, using LCC / OpenMRNIDF, for the ESP32 family of MCUs

These projects were created using Kicad 2013.06.11 (https://launchpad.net/kicad) under CentOS 6 and Kicad 4.0.7 under Ubuntu 18.04. Each subdirectory is one project, and contains a schematic and PCB design or contains a program for one (or more) projects. There is also software for the boards using OpenMRNIDF (C++ library for OpenLCB/LCC) for these projects.

What microcontroller does the ESP32-Feather-6B6L use?

The ESP32-Feather-6B6L is built around the TCAN332DR, from the ESP32 family.

How big is the ESP32-Feather-6B6L PCB?

The ESP32-Feather-6B6L measures 86.4 × 78.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-Feather-6B6L?

36 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32-Feather-6B6L design files?

From the RobertPHeller/ESP32-LCC repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32-Feather-6B6L design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which RobertPHeller chose for the repository.

Can I test firmware for the ESP32-Feather-6B6L 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.
