FM-Radio: common questions
What microcontroller does the FM-Radio use?
The FM-Radio is built around the ESP32-S3-MINI-1U, from the ESP32 family.
How big is the FM-Radio PCB?
The FM-Radio measures 49.4 × 57.2 mm, has 4 copper layers and is 1.786001 mm thick.
How many components are on the FM-Radio?
64 components, from 39 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 FM-Radio design files?
From the zOnlyKroks/pcb-consortium 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 FM-Radio design in my own project?
Yes, under the terms of its CC0-1.0 license, which zOnlyKroks chose for the repository.
Can I test firmware for the FM-Radio 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.
