RC-W25: common questions
What microcontroller does the RC-W25 use?
The RC-W25 is built around the C5736265, from the ESP32 family.
How big is the RC-W25 PCB?
The RC-W25 measures 27.4 × 60 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the RC-W25?
58 components, from 34 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 RC-W25 design files?
From the Electrium-Mobility/RC-W25 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 RC-W25 design in my own project?
The repository has no license, so all rights stay with Electrium-Mobility. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the RC-W25 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.
