About the Panel PCB

Panel is an open source ESP32 PCB design by gregdavill, published on GitHub. It is a 4-layer board measuring 95.2 × 81.7 mm, with 49 components from 28 distinct parts.

Its main chip is the ESP32-S2, from the ESP32 family. Other key parts include the USBLC6-2P6, TLV62569DRLR and W25Q32JVZPIQ. By type, the board carries 16 capacitors, 16 resistors, 5 inductors, 4 ICs, 3 transistors and 1 crystal.

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

From the project

Compact 4 digit 7-segment clock display controlled with an ESP32-S2

~ Current Status: Prototype boards ordered ~

Note: This design was performed in KiCad nightly , you will need a Nightly build to open and edit these source files.

A Compact 4 digit 7-segment clock display with an ESP32-S2 control board.

It is powered off a USB-C connection on the side of the unit, and features 1 button.

This design will become a desk clock that sets it's time from your local WiFi using NTP.

Panel: common questions

What microcontroller does the Panel use?

The Panel is built around the ESP32-S2, from the ESP32 family.

How big is the Panel PCB?

The Panel measures 95.2 × 81.7 mm, has 4 copper layers and is 0.8 mm thick.

How many components are on the Panel?

49 components, from 28 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Panel design files?

From the gregdavill/wizard-flute repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Panel design in my own project?

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

Can I test firmware for the Panel 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.
