Questions
How big is the PTN PumpControlBoard PCB?
It measures 53.1 × 81.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PTN PumpControlBoard use?
115 parts, built around the TLV9002QDRQ1, EMC2305-1-AP-TR, LMR33630ADDA and NVMFWS1D7N04XMT1G-VB. 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 PTN PumpControlBoard KiCad files?
From the lhr-solar/PS-PumpController repository on GitHub, at the commit this page was made from: the board is hardware/PTN-PumpControlBoard.kicad_pcb and its schematic hardware/Fans+Pump.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PTN PumpControlBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask lhr-solar before reusing the design.
