M5Stack Programmable Power Supply Module 13.2


Description

PPS Module 13.2 is a programmable power supply module. This module employs STEP-DOWN buck technology, supports a wide DC 9-36V input voltage, and integrates an STM32 control processor and AD8418 high-resolution current amplifier. Through high-precision closed-loop control, it achieves a rated output power of 100W (peak 150W) with high-precision current and voltage output, capable of delivering 0.5~30V/0~5A, with a read-back accuracy of ±30mV/5mA. Additionally, the module incorporates isolation chips CA-IS3020S and B0505S-1WR3, providing electrical isolation for both the power supply and the communication bus. The output interface uses standard 4MM banana plug sockets, with a positive and negative pole spacing of 19mm. Each module is calibrated for full-range accuracy before leaving the factory, and users will need to separately purchase a compatible DC power adapter. This module is suitable for use in scientific research experiments, industrial automation, embedded system development, and DIY projects requiring an adjustable power supply.

NOTESIf you use PPS Module 13.2, connect an external 12VDC power supply. Otherwise, the system displays a message indicating that no I2C device is available and the device does not work. The maximum output depends on the output capacity of the input DC power supply.Power detectionpower input detection interface (5-24V@5A): - USB PD power input - Relay Base power input
