Description: 1. Overview: M5 Stack Solid State Relay Unit (BT136S) is a WiFi-enabled, compact, and versatile IoT component designed for remote control of electrical appliances using solid state relays (SSRs). 2. Features: It comes with three relay channels, each capable of handling up to 30A/250VAC or 16A/35VDC load. The unit supports both normal and latching relay modes. WiFi connectivity enables remote control via M5 Stack App or custom scripts. 3. Ease-of-use: The BT136S is compatible with the M5Stack system, allowing users to build their IoT projects using popular development boards like ESP32 and ESP8266. This makes it a perfect addition for hobbyists and professionals in automation and home control projects. 4. Reliability: Solid state relays ensure long life, noiseless, and more reliable operation compared to mechanical relays. BT136S also includes over-current and over-voltage protection for safety and added durability. 5. Integration with MQTT: The relay unit supports MQTT protocol, e
