The RockBLOCK does not have a charging circuit. You'll need to charge your batteries externally.

There are various FTDI USB cables, the precise model used with our products is the TTL-232R-3V3, and it's available to purchase from our shop or from various electronics outlets globally.

RockBLOCK 9602

RockBLOCK 9602 has a 0.1" header, split into 2 sections. Pins 1-6 are designed to be compatible with the FTDI TTL-232R-3V3 cable for USB hosts. If you're not using this cable, you do not need to connect these pins.
