Single Sided PCB for MMDVM Hotspot with RF7021SE module and Blue Pill STM32DUINO
This project provides a simple, singled sided PCB for the MMDVM_HS Hotspot main repo. Can be easily made using toner transfer, has very few wires. Just order the components (RF7021SE from Aliexpress and Blue Pill STM32DUINO clone) and put on board. Do not forget to replace the RF7021SE standard oscillator with a supported TCXO.
The second pcb design called stick is much smaller, and has a more logical led layout. But it requires a few more via wires if made as a single sided board. Most connecting wires are only used if the optional connectors are used. The single pin connector in the middle of the board is in fact a bottom / top ground plane connection for a two sided design. No need to use it on a single sided pcb.

Questions
How big is the Stm32duino PCB?
It measures 87.6 × 48.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stm32duino use?
20 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Stm32duino KiCad files?
From the db4ple/MMDVM_HS_PCB_Single repository on GitHub, at the commit this page was made from: the board is stm32duino.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32duino design in my own project?
Its repository states no licence, so its author keeps all rights: ask db4ple before reusing the design.
