BOARD LAYOUT

POWER CIRCUIT

ADuC-IO7020

can take power from:

PWR_JACK where 12 V DC, is applied by external power source.

The board power consumption at first, without Relays is: about 40

mA, when all

Relays are working the consumption is 180 mA.

RESET CIRCUIT

ADuC-IO7020

reset circuit is includes R1 (1k) pull-up, U4 (MCP130T), ADuC7020

pin 19 and RST button.

CLOCK CIRCUIT

Quartz crystal 32.768 KHz is connected to

ADuC7020

pin 24 (XCLKO) and pin 25

(XCLKI).

JUMPER DESCRIPTION

There are no jumpers on this board.
