The relay expander increases the number of relays for controlled by the ESP32R4 controller. Can connect up to 3 expanders with 8 relays each. Therefore, it is optimal to connect no more than 3 additional relay expanders (4 relays on the ESP32R4 controller itself + 24 (3 * 8) relays for expanders, 28 in total).
ESP32R4 controller is built and powerful with the ESP32 microcontroller, 2.4 GHz Wi-Fi, and Bluetooth LE 4.2 (BR/EDR + LE). Two CPU core(s) with adjustable clock frequency, up to 240 MHz, for controlling 4 relays, 4 buttons, the sound buzzer, and additional embedded modules for additional interface and color TFT touchscreen. ESP32R4 with ESP32 microcontroller can perform as a complete standalone system or as…
