I believe this setup mirrors the functionality of official VE.Direct cables at a much lower price. All the usual caveats apply. No guarantees, might have comms problems, no support, etc…

Parts list:

  • 2.0mm JST connector $0.40/ea (AliExpress link) (Technically known as PH Connector)
  • PL2303HX USB to UART TTL Cable $1.20 (AliExpress link)
  • ADUM1201 magentic isolator board $1.35 (ali express link: a[dot]aliexpress[dot]com/_mL6Z9jV)

Total: $2.95

Probably would want to protect the isolator board with some heat shrink tube, but it works great!

yep make 10x cables for the price of 1x victron cable

they make a mini version of the ADUM1201 as well

could also use 90 deg headers to slim line it more for heatshrink / hot glue / poxy filling

Yeah I recently got some 90 degree headers, that would make a nicer cable.
