Questions
How big is the ProgrammingAdapter PCB?
It measures 88 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ProgrammingAdapter use?
24 parts, built around the ATTINY84A-PU, NRF24L01, AM312 and M2.5. 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 ProgrammingAdapter KiCad files?
From the hagego/SmartHome repository on GitHub, at the commit this page was made from: the board is nRF24/PCBs/ProgrammingAdapter/ProgrammingAdapter.kicad_pcb and its schematic nRF24/PCBs/ESP2nRF24/ESP2nRF24/ESP2nRF24.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ProgrammingAdapter design in my own project?
Its repository states no licence, so its author keeps all rights: ask hagego before reusing the design.
