ArmLabRadio: common questions
What microcontroller does the ArmLabRadio use?
The ArmLabRadio is built around the C79861, from the STM32 family.
How big is the ArmLabRadio PCB?
The ArmLabRadio measures 57.2 × 57.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ArmLabRadio?
90 components, from 53 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 ArmLabRadio design files?
From the explosion33/ArmLabRadio_PCB 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 ArmLabRadio design in my own project?
The repository has no license, so all rights stay with explosion33. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ArmLabRadio 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.
