About the Actuator Board V1

Actuator Board V1 is an open source ESP32 PCB design by colin-skinner, published on GitHub. It is a 2-layer board measuring 53.8 × 29.2 mm, with 19 components from 17 distinct parts.

Its main chip is the ESP32-S3-WROOM-1U-N16, from the ESP32 family. Other key parts include the DS3232M. By type, the board carries 8 resistors, 4 capacitors, 2 ICs, 2 connectors, 2 diodes and 1 fuse.

It belongs with the rf & radio, iot & wireless and sensors designs in this gallery.

The main goal of this project is not simply to learn, but to focus on following through and finishing each sprint. Additionally, with working prototypes and code, I plan to use my designs to help aspiring engineers who want to develop these skills as well (open-source, potentially?).

Each stage will act as a sort of version that had a fully working system. When I add changes that completely break a system, then I'll re-rev the design for a new version.

Actuator Board V1: common questions

What microcontroller does the Actuator Board V1 use?

The Actuator Board V1 is built around the ESP32-S3-WROOM-1U-N16, from the ESP32 family.

How big is the Actuator Board V1?

The Actuator Board V1 measures 53.8 × 29.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Actuator Board V1?

19 components, from 17 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 Actuator Board V1 design files?

From the colin-skinner/Cesium 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 Actuator Board V1 design in my own project?

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

Can I test firmware for the Actuator Board V1 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.
