Questions
How big is the HMSensor StepUp PCB?
It measures 20 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HMSensor StepUp use?
30 parts, built around the ATMEGA328P-AU, CC1101RGP and TLV61224DCK. 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 HMSensor StepUp KiCad files?
From the pa-pa/HMSensor repository on GitHub, at the commit this page was made from: the board is HMSensor-StepUp/HMSensor-StepUp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the HMSensor StepUp design in my own project?
Its repository states no licence, so its author keeps all rights: ask pa-pa before reusing the design.
