Tips

  • The big pad on the bottom side is a dead pad. No any circuit network on it.
  • Solder the positive wires as close as possible to both sides of the current sensing resistor.
  • 2 ears for mounting can be cut off if you don’t need it.
  • If the CAN wires are too long, bridge the “120R” jumper.

Compact and Very Useful
Color: White
Nice compact version for smaller setups. Works well and the USB-C port is a great addition. Only wish the cord was slightly longer, but overall it’s very useful.
