Power supply section
The board contains a voltage regulator. You can choose between applying a 4-10V
unregulated supply voltage at the DC jack (like the battery eliminator included in the kit), or
the screw terminal where a battery pack or some other supply can be connected. The on-
board regulator drops the voltage to 3.0V. A green LED will light up the board is connected to
a power source.
Input supply voltage range is 4 – 10 V. A series diode protects the circuit against wrong
polarity.
The current supply to the module is through the jumper at P13, pin 3 and 4. An ampere meter
can be connected here in order to measure the DC current drawn by the module. Remove the
jumper and replace by an ampere meter in order to measure the current. The location of P13,
pin 3 and 4, are shown in the figure below.

Note: To ensure proper Power-On Reset (POR) the wall socket end of the AC/DC battery
eliminator should be inserted first, and then the DC-jack into the board. If the VCC power-on
rise-time specification is not met, the board may need the RESET to be activated to ensure
correct start-up.
