Prod board: common questions

What microcontroller does the Prod board use?

The Prod board is built around the ESP32-WROVER-IE(16MB), from the ESP32 family.

How big is the Prod board?

The Prod board measures 90 × 70 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Prod board?

125 components, from 38 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 Prod board design files?

From the family-mruby/narya-board 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 Prod board design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which family-mruby chose for the repository.

Can I test firmware for the Prod board 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.
