4. POWPER SUPPLY
The kit works at 3.6~6.0V and the recommended working voltage is 5V. There are three
groups of power inputs: P4 (DC socket), P3 (Pin header) and Battery socket on the back of
board. Users only can choose one of them in use.
5. FUNCTION DISCRIPTION
When the kit is powered on, the LCD on board will show the default parameters for the first
use or the settings of last operation. Users can press the SET button to start the setting of
