Power Supply

Power is supplied to the MCBx51 board by an external 8-12 Volt DC power supply which is capable of providing 300-500mA. The connection uses a standard 5.5mm barrel plug with a 2.1mm center hole providing positive voltage.

The Power LED indicates that +5VDC is present on the board.

The 7805 voltage regulator IC2 generates 5 Volts DC. A second 78L05 voltage regulator IC6 reduces the noise for the 251A1 A/D converter .
