Specification:

• Compatible with nodemcu 18650 charging system integration
• The indicator LED (green means full red means charging) can be used while charging
• Switch control power supply
• SMT connector can be used for sleep mode · 1 additional LED programmable (gpio16)
• 0.5a charging current
• 1A output
• Overcharge protection
• Over discharge protection
• 10 digital pin read/write/interrupt/PWM/I2C/line support (except D0)
• If the battery is in the wrong direction, the charging chip will be destroyed.

Features :

• 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 and NodeMCU.
• 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 powered or not.
• OLED’s SDA and SCL connected to the D1 pin and the D2 pin respectively.
• The five buttons are controlled by FLASH, RESET, 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, and 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.
