4-channel 12V computer USB control switch, no drive relay module, PC intelligent controller

Module Introduction

This module adopts HID technology, foreign trade quality, no need for any drivers, and comes with an application program in the download material, plug and play. Supports WIN7, XP 32-bit, and 64 bit systems, making it easy and convenient to use. We provide application programs and C++secondary development library code. There is no VB code, but they are all DLL files. Therefore, whether it is possible to operate on VB requires friends who are familiar with VB to try it out themselves. Due to engineers pursuing further studies abroad, we are unable to provide you with technical support. Therefore, please review the information before taking photos,
