ESP8266 serial port wifi module USB to serial port CP210X expansion IoT development module

Features

• One AD inputs.
• Micro USB inputs.
• One programmable LED (D0).
• Integrated 18650 battery charging and discharging system.
• One switch controls whether the 18650 battery is powered or not.
• OLED’s SDA and SCL connect to the D1 pin and the D2 pin respectively.
• The five buttons are controlled by FLATH, RSET, D5, D6, and D7 respectively.
• The 5 Digital pins can configure the write/read/interrupt/pwm/I2C/one-wire supported separately.
• Operation and NodeMCU consistent, adding a programmable LED, you can use GPIO16 to control, display 8266 running status and other functions. Integrated OLED and five button, more convenient for development.
• The design concept originates from the open source project NodeMCU, and the development board integrates 18650 charging and discharging systems with charging and discharging protection. At the same time, a OLED and five directional buttons are integrated to facilitate the development.
