About the Kicad PCB

Kicad is an open source ESP32 PCB design by jacksterb1234, published on GitHub. It is a 2-layer board measuring 74.3 × 54.6 mm, with 17 components from 13 distinct parts.

Its main chip is the ESP32_30pin, from the ESP32 family. Other key parts include the DRV8833PW, TSOP382XX and POLOLU_BREAKOUT_A4988. By type, the board carries 7 capacitors, 5 connectors, 3 ICs, 1 module and 1 resistor.

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

From the project

A fully custom table tennis serving robot designed for serve-receive practice. Features dual-axis spin control (pitch and yaw), a printed spindexer, and a Bluetooth mobile app for wireless control. Powered entirely from a single USB-C connection.

Kicad: common questions

What microcontroller does the Kicad use?

The Kicad is built around the ESP32_30pin, from the ESP32 family.

How big is the Kicad PCB?

The Kicad measures 74.3 × 54.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kicad?

17 components, from 13 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 Kicad design files?

From the jacksterb1234/Ping_Pong_Machine 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 Kicad design in my own project?

The repository has no license, so all rights stay with jacksterb1234. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Kicad 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.
