BluetoothReceiver: common questions

What microcontroller does the BluetoothReceiver use?

The BluetoothReceiver is built around the STM32F413CHUx, from the STM32 family.

How big is the BluetoothReceiver PCB?

The BluetoothReceiver measures 48.4 × 40 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the BluetoothReceiver?

41 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the BluetoothReceiver design files?

From the BlockWorker/ModularAudio repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the BluetoothReceiver design in my own project?

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

Can I test firmware for the BluetoothReceiver without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
