2.4.3 Power Connections

The board can be powered by using the on-board micro USB connector. An on-board LDO provides 3.3 V

for the CC3200 and the rest of the board to operate. This supply can be isolated from the LDO using the

jumpers on the board.

Reference Usage Comments

J12 Current Measures the current flowing into the CC3200 device.

measurement

J13 Board power Short: Supply the board power from the on-board LDO.

Open: Supply the board power from the J20 (battery connector)

J19 5 V power 5 V output from the USB VBUS (has a diode drop of up to 0.4 V)

J20 3.3 V power input Can be used to power the board from an external 2XAA battery pack. It has in-built reverse

voltage protection to prevent the battery from being plugged in the reverse manner.

2.4.4 UART Signals

The board supports a USB-based virtual COM port, which is used on the FTDI device FT2232D. There

are two ports on the FT2232: the first port is dedicated for the emulation (JTAG/SWD) and the second port

is used for the virtual COM port. The UART can also be routed to the 20-pin connector and the selection

is performed using jumpers on the board.
