Wemos ESP-Wroom-02 WiFi module with ESP8266 battery

Product detailed description

The development board integrates the ESP8266 and 18650 battery. The standard 18650 battery can work up to 17 hours,

Attention: if the battery is recharged, the charging chip will be destroyed

Technical parameters:

- integrated 18650 battery charging system
- lED indicator - green - fully charged, red - charging in progress
- can work and charge at the same time
- 1x power switch
- 1x SMT connector for sleep mode
- charging current: 0.5A
- output current: 1A
- overload protection
- 10 digital pins
- pWM, I2C support
- 1x analog input

Features:

- aD input
- micro USB input
- programmable LED (D0)
- circuit AUTO PROGRAM.ESP8266 (ESP-Wroom-02 With TELEC), equivalent with NodeMCU
- analog input (AD): built-in divider resistor (AD = 220K - ADC - 100K = GND)
- sOLDER terminal available for sleep mode
- compatible with Arduino and NodeMCU
- operation and charging are possible at the same time
- 18650 charging circuit including 5V boost circuit with TP5410
- built-in overload protection
- LED: red = charging, green = full charge
- integrated 18650 battery charging and discharging system
- one switch controls whether the 18650 battery is powered or not
- SLEDOLED and SCL connected to pins D1 and D2
- 5 buttons are controlled by FLASH, RESET, D5, D6 and D7
- 5 digital pins can configure separately writable/writable/interruptible/PWM/I2C/single-ended
- operation and consistent NodeMCU, by adding programmable LEDs, you can use GPIO16 to control, display the 8266 operating status and other functions.
- integrated OLED and five buttons, more convenient for development
- the design concept is based on NodeMCU open source project and the development board integrates 18650 charge and discharge systems with charge and discharge protection
- at the same time, OLED and five directional buttons are integrated to facilitate development.
