ESP32-WROOM 5-60V 2Ch 10A Wifi Relæ Module har en indgangs spænding på 5-60V, og bliver kontrolleret fra ESP32-WROOM chippen. Perfekt til alle IoT projekter.
Elsai DC powered esp32 dual relay development board is equipped with esp32-wroom-32e
WiFi & ble module, fully led out from / O port, supports dc5-60v power supply mode. Applicable to esp32 secondary
Development and learning, smart home, wireless control and other occasions.
1. Onboard mature and stable esp32-wroom-32e module with large capacity of 4m byte flash; 2. The I / O port and UART program download port of esp32 module are all led out to facilitate secondary development; 3. Power supply voltage dc7-60v;
4. On board esp32 module IO0 programmable key and reset key;
5. Esp32 supports the use of Arduino ide development tools and provides reference programs under the Arduino development environment;
6. On board 2-way 5V relay, output switch signal, suitable for controlling loads with working voltage within AC250V / dc30v;
7. One programmable led and relay indicator on board.
Program Upload: (Arduino IDE)
GND, Rx, TX and 5V of burning and writing port esp8266 are respectively connected with GND, TX, RX and 5V of external TTL serial port module. When downloading, 00 needs to be connected with GND, and then disconnect 00 from GND after downloading.
NC: normally closed end, short circuited with com before the relay is pulled in, and suspended after it is pulled in; COM: public end;
No: normally open, the relay is suspended before closing, and is short circuited with com after closing.
