HF PA Radio Interface: common questions
What microcontroller does the HF PA Radio Interface use?
The HF PA Radio Interface is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.
How big is the HF PA Radio Interface PCB?
The HF PA Radio Interface measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the HF PA Radio Interface?
180 components, from 49 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 HF PA Radio Interface design files?
From the M0LTE/pi-transceiver 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 HF PA Radio Interface design in my own project?
The repository has no license, so all rights stay with M0LTE. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the HF PA Radio Interface without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
