Test rf: common questions
What microcontroller does the Test rf use?
The Test rf is built around the STM32WL55CCU6TR, from the STM32 family.
How big is the Test rf PCB?
The Test rf measures 15 × 31 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Test rf?
38 components, from 23 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 Test rf design files?
From the akularya6-del/Device1-Rev2-Fixed repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Test rf design in my own project?
The repository has no license, so all rights stay with akularya6-del. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Test rf 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.
