RRST-ESP32 Rev.1: common questions

What microcontroller does the RRST-ESP32 Rev.1 use?

The RRST-ESP32 Rev.1 is built around the ESP32-WROOM-32E, from the ESP32 family.

How big is the RRST-ESP32 Rev.1 PCB?

The RRST-ESP32 Rev.1 measures 30.5 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RRST-ESP32 Rev.1?

34 components, from 19 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 RRST-ESP32 Rev.1 design files?

From the RRST-NHK-Project/kicad-ws 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 RRST-ESP32 Rev.1 design in my own project?

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

Can I test firmware for the RRST-ESP32 Rev.1 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.
