Testbed mcu: common questions

What microcontroller does the Testbed mcu use?

The Testbed mcu is built around the ESP32-WROVER-E, from the ESP32 family.

How big is the Testbed mcu PCB?

The Testbed mcu measures 69.6 × 55.9 mm, has 2 copper layers and is 1.646 mm thick.

How many components are on the Testbed mcu?

19 components, from 9 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 Testbed mcu design files?

From the OpenAir-Lab/capstone-project repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Testbed mcu design in my own project?

Yes, under the terms of its MIT license, which OpenAir-Lab chose for the repository.

Can I test firmware for the Testbed mcu 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.
