ESP32 UniversalRemote: common questions

What microcontroller does the ESP32 UniversalRemote use?

The ESP32 UniversalRemote is built around the ESP32-WROOM-32U, from the ESP32 family.

How big is the ESP32 UniversalRemote PCB?

The ESP32 UniversalRemote measures 130 × 130 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32 UniversalRemote?

53 components, from 22 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 ESP32 UniversalRemote design files?

From the qvinhdao/ESP32_UniversalRemote 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 ESP32 UniversalRemote design in my own project?

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

Can I test firmware for the ESP32 UniversalRemote 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.
