Powering the Sensor Board
The sensor board can be power in several different ways, thus giving flexibility and ease of
use.
Power source
Jumper position/RED
Comment
USB power 1A
VCC - VCC_EXT
Make sure to use a USB power source
capable of 1 A. A PC does normally not offer
that high current
Extern Volt 4-11 V
/9V battery
VCC - VCC_EXT
Connect through pin holes at edge. Here a
9V battery can also be connected.
NB: Using VCC > 6V, continuous
transmission test mode cannot be used.
Battery 3.0/3.6V
VCC - OFF/BAT
Battery can be connected
USB PC
VCC
– VCC_PC
Only for RC1180MSM. The others draw too
high current
The sensor board is setup with a green power on LED, D1. This draws 2 mA and is always
on. In case of using the sensor board for battery operated proof of concept, this LED need to
be removed to ensure low power consumption
Controlling and Configuring Sensor Board
The sensor module can be controlled and configured through UART. For ease of use the
UART is connected through a UART-to-USB bridge from FTDI and to a micro USB contact.
By connecting a computer to this USB connector on the sensor board, a terminal emulator
program can be used to communication with the module. There is also a config button on the
board to easily put the module in configuration mode. See datasheets [3][4][6][7] and user
manual [2][5] for details on communication via UART.
