About the Moco PCB

Moco is an open source ESP32 PCB design by dstutman, published on GitHub. It is a 2-layer board measuring 34 × 34 mm, with 48 components from 30 distinct parts.

Its main chip is the ESP32-C3, from the ESP32 family. Other key parts include the TPS562201, TMAG5273, DRV8311 and TJA1462ATK/0Z. By type, the board carries 26 capacitors, 10 resistors, 5 ICs, 5 connectors, 1 crystal and 1 inductor.

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

From the project

A compact and cost effective BLDC servo controller.

Moco is a closed-loop brushless-motor controller. It is meant to glom onto the back of a 2805 gimbal motor and provide precise torque, speed, and position control.

Moco: common questions

What microcontroller does the Moco use?

The Moco is built around the ESP32-C3, from the ESP32 family.

How big is the Moco PCB?

The Moco measures 34 × 34 mm, has 2 copper layers and is 0.9242 mm thick.

How many components are on the Moco?

48 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Moco design files?

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

Can I use the Moco design in my own project?

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

Can I test firmware for the Moco 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.
