Its main chip is the ESP32-C3-MINI-1-N4, from the ESP32 family. Other key parts include the ICE40UP5K-SG48ITR, W25Q64JVSSIQ, STM32H563ZIT6, LAN8742AI-CZ-TR and APS6404L-3SQR-ZR. By type, the board carries 129 capacitors, 123 resistors, 29 ICs, 6 connectors, 6 diodes and 3 crystals.

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

From the project

An open hardware bench tool that plugs into your CI: sensor sim, CAN, analog I/O, power control, and a Python SDK with pytest integration

NOTE1: Some tagged versions will have obvious mistakes in them, but as those got built, they're in the repo for historical reasons.

NOTE2: Don't build these boards yourself without any necessary changes. The current tagged versions are not production-ready yet.

Benchpod: common questions

What microcontroller does the Benchpod use?

The Benchpod is built around the ESP32-C3-MINI-1-N4, from the ESP32 family.

How big is the Benchpod PCB?

The Benchpod measures 82 × 90 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Benchpod?

306 components, from 76 distinct parts. The full bill of materials is listed on this page.

Where can I download the Benchpod design files?

From the embeddedci-com/benchpod repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Benchpod design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which embeddedci-com chose for the repository.

Can I test firmware for the Benchpod 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.
