GMAX brand mini access control board (relay module) with Tuya WIFI support, model GM-Sboard-3-Tuya-WIFI. This compact standalone controller board is designed to work in conjunction with an external Wiegand RFID reader to securely manage electronic door locks. Because the controller unit is installed inside the secure perimeter, it eliminates the risk of unauthorized entry caused by tampering with the external reader. Its primary advantage is the built-in Tuya WIFI connectivity, allowing administrators to remotely unlock doors, manage user credentials, and monitor access logs from anywhere using the Tuya Smart or Smart Life mobile app.
