2.4 Cable Connections
When the PCB is first taken out of the box, the only cable connection required is a Standard-A to micro-B
USB cable. Connect the micro-USB plug to J21 and the other end (standard-A plug) of the USB cable into
a USB2or USB3 port of a computer.
If the PCB is split into two sections so that the lower half can be used as a stand-alone USB2ANY, a
keyed 10-pin ribbon cable must be connected between J19 and J16 to control the TPS65291 device
through SPI.
Figure 4 shows these connections.

WARNING
Do not split the PCB into two sections without protection.
Protective glasses and gloves should be worn. First, use wire
cutters to partially sever the connections between the two sections
on both top and bottom. Then, connect one end to a rigid surface
with a vice grip. Finally, grab the other end of the PCB firmly with
pliers and bend back and forth slowly until the two sections
separate.
