About the WIBL PCB

WIBL is an open source ESP32 PCB design by CCOMJHC, published on GitHub under the MIT license. It is a 2-layer board measuring 110 × 56 mm, with 107 components from 54 distinct parts.

Its main chip is the ESP32-WROOM-32E-N4, from the ESP32 family. Other key parts include the SN65C1168N, TJA1051T/3, LSM6DS3TR-C, AMS1117-3.3 and RFM-0505S. By type, the board carries 35 resistors, 22 capacitors, 7 ICs, 7 diodes, 4 transformers and 3 LEDs.

It belongs with the iot & wireless designs in this gallery.

This directory contains all of the files required for the KiCAD projects associated with the WIBL project. You will need at least v. 9.0 of KiCAD to use the files.

There have been some reported issues with project files containing hard-coded directory and filenames, which makes them a little less portable than would be preferred. If this happens, you can point at the new location of schematic symbols and footprint libraries by:

WIBL: common questions

What microcontroller does the WIBL use?

The WIBL is built around the ESP32-WROOM-32E-N4, from the ESP32 family.

How big is the WIBL PCB?

The WIBL measures 110 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the WIBL?

107 components, from 54 distinct parts. The full bill of materials is listed on this page.

Where can I download the WIBL design files?

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

Can I use the WIBL design in my own project?

Yes, under the terms of its MIT license, which CCOMJHC chose for the repository.

Can I test firmware for the WIBL 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.
