Fm usb mpx tuner: common questions
What microcontroller does the Fm usb mpx tuner use?
The Fm usb mpx tuner is built around the STM32F072CBU6TR, from the STM32 family.
How many components are on the Fm usb mpx tuner?
109 components, from 64 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 usb mpx tuner design files?
From the LyonelB/fm-usb-mpx-tuner repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.
Can I use the Fm usb mpx tuner design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which LyonelB chose for the repository.
Can I test firmware for the Fm usb mpx tuner 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.
