Module size: 7mmx35mm, 5 pin holes are reserved in the hardware (the factory default does not match the pins)
The pin hole diameter is 0.6mm, and the pin spacing is 1.27mm.

LD2410B module directly through an IO pin output the detected target state (someone high, no one low), but also through the serial port in accordance with the prescribed protocol for the output of the detection results data, the serial output data contains the target state and distance auxiliary information, etc., the user can be used flexibly according to the specific application scenarios. The module power supply voltage is 5V and the input power supply capacity is required to be greater than 200mA. The module IO output level is 3.3 V. The default baud rate of the serial port is 256000, with 1 stop bit and no parity bit.
