  • Uses NXP MC34671 li-ion charging IC.
  • Power with micro-usb. Intended to be low current battery charger <300ma per channel. I have one of these set up to charge at 100ma.
  • The USB-micro socket is all SMD. Added vias to the pads for strength but should have used type with through-hole tabs on the socket body.
  • The IC takes a wide range of input voltage so this can be run off more than 5v. Should have included a 12V socket.
  • 6 channels.
  • Added buttons on the EN lines so they can be individually restarted. Included pull-downs on EN too.
  • Uses Molex MicroFit 3.00 pitch sockets to plug batteries in.
  • Assembled and works great.
