Description

Onboard mature and stable ESP-12F WIFI module, large capacity 4M BYTE FLASH; The I/O port and UART program download port of the WIFI module are all led out to facilitate secondary development; Onboard AC-DC switching power supply module, power supply mode supports AC90-250V/DC7-30V/5v; Onboard WIFI module RST reset button; ESP-12F supports the use of development tools such as ECLIPSE/ARDUINO IDE, and provides ARDUINO Reference program in the development environment; Onboard 4 5V relays, output switch signal, suitable for controlling the working voltage of AC Load within 250V/Dc30V; Onboard power indicator, 1 programmable LED and relay indicator. 4. The first reset button of the wifi module on the board; 2. The I/O port of the WIFI module and the UART program download port are all led out to facilitate secondary development; 1. On-board and stable ESP-12F wifi module, large-capacity 4m bytes flash memory; 3. The power supply mode supports AC90-250V/DC7-30V/5V; 5. ESP-12F supports the use of development tools such as eclipse / for ide, and provides reference programs in the for development environment; 6. There are 4 5v relays on the board, which are used to switch output signals and are suitable for controlling loads whose working voltage is in the AC range. 7. On-board power indicator, 1 programmable LED and relay. Power supply: 4 channels: AC90-250V/DC7-30V/5V Writing mouth: The GND, RX, TX, and 5V of ESP8266 are connected to the GND, TX, RX, and 5V of the external TTL serial port module respectively. The IO0 should be connected to the GND when the download is complete. Disconnect the IO0 and GND after the download is complete. Relay output: NC: normally closed end, short connect with COM before relay closing, suspended after closing; COM: public terminal; NO: normal start, the relay is suspended before closing, and short connected with COM after closing.
