Pong
About the Pong PCB
Pong is an open source ESP32 PCB design by Pegoku, published on GitHub. It is a 2-layer board measuring 165 × 100 mm, with 13 components from 9 distinct parts.
Its main chip is the ESP-WROOM-32E, from the ESP32 family. Other key parts include the AZ1117H-3.3TRG1 and AMS1117-5.0_C347223. By type, the board carries 3 ICs, 3 connectors, 3 battery holders, 3 capacitors and 1 LED.

Pong: common questions
What microcontroller does the Pong use?
The Pong is built around the ESP-WROOM-32E, from the ESP32 family.
How big is the Pong PCB?
The Pong measures 165 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pong?
13 components, from 9 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 Pong design files?
From the Pegoku/ClassPCBs 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 Pong design in my own project?
The repository has no license, so all rights stay with Pegoku. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pong 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.
