ESP32-WROOM 5-60V 2Ch 10A Wifi Relæ Module

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.

Tekniske detaljer:

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.
Functional features

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.

Installere ESP package (Arduino IDE)

• Åben Arduino IDE (Download her)
• Klik “Fil/Egenskaber”
• Indtast dette link i feltet “Additionel Board Manager URL’s”
• Link “https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json“
• Klik OK
• Åben “Værktøj/Board/Boards manager” (Lad programmet opdatere)
• Find “ESP32” og installere
• Klik derefter “Værktøj/Board” og find (DOIT ESP32 DEVKIT V1)
• “Værktøj/Programmer” skal være “AVR ISP”
• Du er nu klar til at sende en kode

Program Upload: (Arduino IDE)
Da dette modul ikke har en USB interface, skal der bruges en “TTL Serial Adapter Module” som sender programmet over i chippen. Du kan købe den her:

• FT232RL FTDI USB 2.0 to TTL Serial Adapter Module

Inden koden kan uploades skal IO0 forbindes til GND imens koden uploades.

Relay output:
NC: normally closed end, the relay is short circuited with com before closing and suspended after closing.
COM: public end.
No: normal opened end, the relay is suspended before closing, and it is short circuited with com after closing.
