Rele wifi: common questions

What microcontroller does the Rele wifi use?

The Rele wifi is built around the ESP32-CAM, from the ESP32 family.

How big is the Rele wifi PCB?

The Rele wifi measures 78.9 × 71.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rele wifi?

42 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rele wifi design files?

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

Can I use the Rele wifi design in my own project?

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

Can I test firmware for the Rele wifi 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.
