  • M5Stack Programmable Power Supply Module 13.2
  • Versatile 9-36V DC input
  • Precise 0.5-30V/0-5A output
  • High-resolution current control
  • Electrical isolation for safety
  • Standard 4mm banana sockets

The M5Stack Programmable Power Supply Module 13.2 is a sophisticated device that utilizes STEP-DOWN buck technology to support a broad range of DC input voltages from 9 to 36V. It is equipped with an STM32 control processor and an AD8418 high-resolution current amplifier for high-precision closed-loop control. This power supply module is capable of delivering a stable output of 0.5 to 30V and 0 to 5A, with a read-back accuracy of ±30mV/5mA. It also features electrical isolation for both the power supply and the communication bus, thanks to the integration of isolation chips CA-IS3020S and B0505S-1WR3. The output interface is designed with standard 4MM banana plug sockets, ensuring compatibility with common connectors. Prior to distribution, each module undergoes a rigorous calibration process to ensure full-range accuracy. The module is an ideal choice for applications in scientific research, industrial automation, embedded system development, and various DIY projects that require a reliable and adjustable power supply.

The maximum output capability of the module is contingent upon the output capacity of the connected DC power adapter.
