Introduction: The LB1101 low-power touch evaluation development board is based on the SAIYUAN SC92L853x low-power touch chip. It features 12 touch buttons and supports power supply from dry batteries and button batteries, with a low power consumption of up to 8μA for all 12 buttons combined. The SAIYUAN 92L853x series MCU supports up to 27 touch circuits, offering high performance, high reliability, and low power consumption characteristics.

Functional Features:

1.  Touch Function: When a touch button is pressed, the buzzer emits a beep sound, and the LED status toggles. When no touch action occurs, the MCU enters low-power mode, and the LED turns off.

2.  Power Switching Function: When the battery power switch is turned on, the device automatically switches to battery power (3.3V) when Type-C is not connected, and switches to USB power (3.3V) when Type-C is connected.

3.  Current Measurement Function: Remove the short cap from H14, switch the multimeter to the current range, connect the red probe to + and the black probe to -, allowing measurement of MCU power consumption.
