Questions
How big is the JK BMS CAN PCB?
It measures 50.3 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the JK BMS CAN use?
66 parts, built around the ATMEGA644P-20AQ, TJA1050T/CM, ADUM1201AR and LMR36510ADDA. 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 JK BMS CAN KiCad files?
From the dremeier/Arduino-JK-BMS-To-Pylontech-CAN-PCB repository on GitHub, at the commit this page was made from: the board is JK-BMS_CAN.kicad_pcb and its schematic JK-BMS_CAN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the JK BMS CAN design in my own project?
Its repository states no licence, so its author keeps all rights: ask dremeier before reusing the design.
