توضیحات محصول

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 · ۱ additional LED programmable (gpio16)
  • ۰٫۵a charging current
  • ۱A output
  • Overcharge protection
  • Over discharge protection
  • ۱۰ 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 – ۱۰۰K = GND).
  • There is a SOLDER terminal for SLEEP MODE.
  • Compatible With Arduino and NodeMCU.
  • Operation and charging are possible at the same time.
  • ۱۸۶۵۰ charging circuit including the 5V boosting circuit with TP5410.
  • Overcharge protection, over-discharge protection built in.
  • LED: Red = Charging, Green = Full charging.
  • ۳۰۰۰ 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.
