WeMos D1 ESP Wroom 02 Board ESP8266 Mini WiFi Nodemcu Module 18650 Battery
- One AD inputs.
- Micro USB inputs.
- One programmable LED (D0).
- AUTO PROGRAM circuit.
- ESP8266 (ESP-WROOM-02 With TELEC) is equivalent to the NodeMCU.
- Analog Input (AD): Built-in dividing resistor (AD = 220K ADC 100K = GND).
- There is a SOLDER terminal for SLEEP MODE.
- Compatible With Arduino andNodeMCU.
- Operation and charging are possible at the same time.
- 18650 charging circuit including the 5V boosting circuit with TP5410.
- Overcharge protection, over-discharge protection built-in.
- LED: Red = Charging, Green = Full charging.
- 3000 mA 18650 It is possible to operate for more than 17 hours on a battery.
- Integrated 18650 battery charging and discharging system.
- One switch controls whether the 18650 battery is on power or not.
- OLEDs SDA and SCL can connect to the D1 pin and the D2 pin respectively.
- The five buttons can be 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 buttons, more convenient for development.
- The design concept originates from the open-source project NodeMCU; the development board integrates 18650 charging and discharging systems with charging and discharging protection. At the same time, an OLED and five directional buttons are integrated to facilitate the development.
