SI4684 controller SMD: common questions

What microcontroller does the SI4684 controller SMD use?

The SI4684 controller SMD is built around the DOIT_ESP32_DEVKIT_V1, from the ESP32 family.

How big is the SI4684 controller SMD PCB?

The SI4684 controller SMD measures 100 × 42.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SI4684 controller SMD?

29 components, from 17 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 SI4684 controller SMD design files?

From the PE5PVB/SI4684-DAB-Receiver 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 SI4684 controller SMD design in my own project?

Yes, under the terms of its GPL-3.0 license, which PE5PVB chose for the repository.

Can I test firmware for the SI4684 controller SMD 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.
