Battery management section
Two batteries are used in the circuit.
Coin cell BT1
BT1 CR2032 (3 V, 225 mAh) is the microcontroller power source in halt mode to keep RTC
running.
Rechargeable battery BT2
BT2 VL2330 (3 V, 50 mAh) is for push button and IrDA operation when mains power is off.

Small signal Schottky diode D11, D12, D13, D14, D5
Diodes (D11, D12, D13, D14, and D5) BAT30KFILM (SOD - 523) based circuit is used to
select the power source for the microcontroller.
Switch SW3
Switch SW3 is the push button switch which is used to control the LCD display modes.
When mains power is on, once the push button is pressed, the LCD display is executed as
per the push button run mode.
When mains power is off, once the push button is pressed, the LCD display is executed as
per the push button low power mode.
IrDA section
IRDA transceiver U6
The IrDA transceiver TFDU4300 is used for IrDA communication.
Jumper J6
Using jumper J6, IrDA transmit and receive pins allow testing of the IrDA section using the
SerialIO GUI.
