The LILYGO T-SimHat series includes three expansion boards for the T-SIMXX series, providing relay control and interface support for industrial and IoT applications. These include the INA219 3-Way Relay Module with DHT11 sensor and QMI8658 IMU, a 3-Way Relay Module without sensors, and the CAN + RS485 + Relay Module for communication tasks. All versions support 5V DC power, GPIO pinouts, and are available with pre-soldered or unsoldered male headers.
