AC/DC Power Supply ESP32 WIFI Blue-tooth BLE 1-channel Relay Module ESP32 C3 Development Board ESP32-C3/ESP-C3-12F

Description:

AC/DC power supply ESP32-C3 single-channel relay development board is equipped with ESP-C3-12F WiFi&BLE module, all I/O ports are drawn out, and supports AC90-250V power supply or DC7-12V power supply mode. Suitable for ESP32-C3 secondary development learning, smart home wireless control and other occasions.

Features

1. Onboard mature and stable ESP-C3-12F module, large capacity 4M Byte Flash;

2. The I/O port of the ESP32-C3 module and the UART program download port are all drawn out to facilitate secondary development;

3. Onboard AC-DC and DC-DC switching power supply modules, the power supply mode supports AC90-250V/DC7-12V;

4. Onboard ESP32-C3 module EN power button and IO9 programmable button;

5. ESP32-C3 supports the use of Arduino-IDE development tools and provides reference programs in the A rduino development environment;

6. One 5V relay on board, output switching signal, suitable for controlling loads whose operating voltage is within AC250V/DC30V;

7. Onboard power indicator, 1 programmable LED and relay indicator.

Programming port:

GND, RX, TX, 5V of ESP32-C3 are respectively connected to GND, TX, RX, 5V of the external TTL serial port module. When downloading, IO9 needs to be connected to GND. After the download is completed, disconnect the connection between IO9 and GND ;

Relay output:

NC: normally closed terminal, short-connected with COM before the relay pulls in, and suspended after the pull-in;

COM: public port;

NO: Normally open, before the relay pulls in, it is suspended, and after the pull-in, it is short-circuited with COM.

Package includes:

1 X ESP32-C3 single-channel relay development board
