c) Functional Features

1. Onboard mature and stable ESP-12F (ESP8266MOD) module, with a large capacity of 32Mbit SPI Flash;
2. All I/O ports and UART program download ports of the ESP-12F module are exported for easy secondary development;
3. Onboard Micro-USB port+DC-5-80V to 5V power supply circuit (recommended to supply DC-12V);
4. Onboard RST reset button;
5. ESP-12F supports Arduino IDE compilation tools and provides reference programs for Arduino development environment;
6. An N-channel MOS transistor with an onboard leakage source voltage of 60V, suitable for controlling loads with a "control operating voltage" within DC60V;

d) Introduction and Explanation

Size: 48mm * 59mm/18g (positioning hole: 3mm)

Interface Introduction

1. ower supply port: 5-80V power supply
2. Output power supply port: Supply voltage within DC60V
3. Output load port: Provides power to the load circuit
4. Serial port burning pin
5. All IO pins
6. Programmable indicator light: IO16 pin control
7. RST reset button (press this button when pulling down the IO0 pin to enter the burning mode)
8. Micro-USB power supply port
9. MCU: ESP-12F (ESP8266MOD) module

Program Download

1. Pull down the IO0 pin and press the button at the same time to enter the burning mode. Refer to the module specification book:

mode	CH-PD(EN)	RST	GPI015	GPI00	GPI02	TXD0
Download mode	1	1	0	0	1	1
Operation mode	1	1	0	1	1	1

Prepare a TTL serial port module (such as CH340) and plug it into the computer USB. The connection method between the serial port module and the development board is as follows:

TTL Serial port module	ESP32 Development board
GND	GND
TX	RX
RX	TX
5V	5V

2. Open the Arduino IDE compilation tool, click on "Tools" in the menu bar, select "Development Board", and choose "ESP-12F Module" as the development board;
3. Open the program you want to download, click on "Tools" in the menu bar, select "Port" and choose the correct port number;
4. After clicking "Upload", the program will automatically compile and download to the development board, as shown below:

5.Finally, power on the development board again or press the reset button to run the program;

6. Provide power to the power supply port of the output terminal (theoretically up to 60V DC, here testing uses 12V DC power supply), and then use a multimeter to measure the voltage value of the load port of the output terminal. The multimeter values in the open and closed states of the MOS transistor are shown in the following figure:
