Other Content
Using Module13.2 PPS requires an external DC 9-36V power supply. Otherwise, the module will show no I2C device and will not work. The maximum output value depends on the output capability of the input DC power supply.
The power input detection interface supports 5-24V @ 5A input detection, including USB PD power input and Relay Base power input. Each module is factory-calibrated for full-range accuracy. Do not modify the last sector of the built-in STM32, as it stores calibration data and changing it may cause the module to malfunction.
