Supply for the module is connected through R17. This can be removed and

replaced by another supply or used to measure the current consumption of

the module.

Figure 9 shows the bottom of the board.

SW1 and SW2 connect the USB interface to the Command Data Interface

lines on the module. This allows the prototype board to be used with the

development kit software or a custom application. When in the “USB

Connected position”, the module is connected to the USB interface. The

“Header Only” position connects the module to the header.

Footprints for 0603 size resistors are on most lines so that pull-ups or

pull-downs can easily be added to the lines. The pads are connected to

CC or GND based on the most common configuration for the module. The

schematic at the end of this document shows how each line is connected.

Note: The onboard 3.3-volt regulator has approximately 400mA available

for additional circuitry when plugged into a PC (60mA with the amplified

PRO). If more current is required, the user must power the board from

an external supply or a USB charger with more current capabilities, up to

1A.
