8-Channel Relay Module WIFI Bluetooth Remote Switch DC5-60V

8-Channel Relay Module WIFI Bluetooth Remote Switch DC5-60V Description

1、Multi Channal Control: This relay module is equipped with 8 relays, supports simultaneous control of multiple devices, convenient and practical. 2、Remote Switch Control: Equipped with WIFI and Bluetooth modules, the relay switch can be controlled remotely, so that the device can be controlled anytime and anywhere. 3、Low Voltage Protection: Relay development board supports DC5‑60V voltage input, and ensure safe use through the protection circuit. 4、The I/0 port of the for ESP32 module and the UART program download port are all drawn out, facilitating learning and application development. 5、Easy to Use: Relay board supports flexible control with one button switch, onboard 1 channel 5V relay, output switching signal, easy to operate.
Item Type: Relay Development Board
Material: ABS
Programming Port: The GND, RX, TX, and 5V of the for ESP32 are respectively connected to the GND, TX, RX, and 5V of the external TTL serial port module. When downloading, IO0 needs to be connected to GND. After the download is completed, disconnect the connection between IO0 and GND; relay output Terminal:
NC: normally closed end, the relay is shorted with COM before pull in, and suspended after pull in; COM: common end; NO: always start, the relay is suspended before pull in, and shorted with COM after pull in.
Features:
1. Mature and stable for ESP32-WROOM-32E module on board, large capacity 4M Byte Flash;
2. The I/0 port of the for ESP32 module and the UART program download port are all drawn out, which is convenient for secondary development;
3. Onboard AC DC switching power supply module, the power supply mode supports AC90-250V;
4. Onboard for ESP32 module RST reset button and IO0 programmable button;
5. for ESP32 supports the use of IDE power builder, providing reference programs under development environment;
6. Onboard 1 channel 5V relay, output switching signal, suitable for controlling and controlling loads with operating voltage within AC250V DC30V;
7. Onboard power indicator, 1 programmable LED and relay indicator.
