About the Boing PCB

Boing is an open source ESP32 PCB design by TaniWanKenobi, published on GitHub. It is a 2-layer board measuring 56.8 × 66.3 mm, with 7 components from 5 distinct parts.

Its main chip is the XIAO-ESP32-C6, from the ESP32 family. Other key parts include the HS96L03W2C03. By type, the board carries 3 switches, 2 ICs and 1 battery holder.

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

From the project

A handheld virtual pet built from scratch — custom PCB, 3D-printed enclosure, and C++ firmware running on a XIAO-ESP32-C6. Feed it, play with it, put it to sleep. Neglect it and it sulks.

1. Install the Arduino IDE and the ESP32 board package. 2. Install Adafruit SSD1306 and Adafruit GFX via the Library Manager. 3. Open firmware/firmware.ino — the IDE will pick up all .h/.cpp files in the folder automatically. 4. Select XIAOESP32C6** as the board and flash.

Boing: common questions

What microcontroller does the Boing use?

The Boing is built around the XIAO-ESP32-C6, from the ESP32 family.

How big is the Boing PCB?

The Boing measures 56.8 × 66.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Boing?

7 components, from 5 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 Boing design files?

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

Can I use the Boing design in my own project?

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

Can I test firmware for the Boing 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.
