This project is a compact, driver-free USB module designed for high-voltage, medium-current output. It emphasizes ease of use, reliability, and flexibility for various control and automation applications. This module offers the following features:
-
24 independent high-voltage outputs: Each output channel is controlled using TPIC6B595 shift registers, which provide the capability for high-voltage and medium-current switching.
-
Dual power options: Can choose between USB bus power and an external 5V supply using on-board jumpers.
-
Simple serial interface: Communicate with the module through a virtual COM port using AT-style commands. You can easily set, get, and clear output states.
-
Device driver-free operation: The module is recognized as a standard USB serial device (based on CH340N), meaning it requires no additional driver installation on most operating systems.
