About the RoboDojo PCB

RoboDojo is an open source ESP32 PCB design by Amoskeag, published on GitHub under the BSD-2-Clause license. It is a 4-layer board measuring 60 × 60 mm, with 63 components from 41 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the TCA9548ARGER, STSPIN250, USBLC6-2P6, MCP73831-2-OT and AP2112K-3.3. By type, the board carries 10 connectors, 10 resistors, 8 capacitors, 7 ICs, 2 switches and 2 diodes.

It belongs with the robotics & motion and dev boards & breakouts designs in this gallery.

RoboDojo: common questions

What microcontroller does the RoboDojo use?

The RoboDojo is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the RoboDojo PCB?

The RoboDojo measures 60 × 60 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RoboDojo?

63 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the RoboDojo design files?

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

Can I use the RoboDojo design in my own project?

Yes, under the terms of its BSD-2-Clause license, which Amoskeag chose for the repository.

Can I test firmware for the RoboDojo 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.
