Battery Charging Board

  • Made this to charge multiple LED hula hoops off one USB. Charge rate is slow (100 mA per output) so usb load is also relatively low.
  • Uses Freescale MC34671.
  • Five (5) outputs.
  • USB Micro power in.
  • 2.5mm mono RCA socket for each output. I use a double ended 2.5mm cable and a 2.5mm socket on my hoops.
  • 3 Status LEDs per output. PWR, FAST, CHRG. They are labeled for 1kOhm but probably use 10k on PWR and FAST to make them dimmer.
  • Resistor labeled on board is for 100 ma charge rate.
  • This has been assembled and is functional.
