The WEMOS D1 Esp-Wroom-02 a microcontroller development board with an ESP8266 WiFi chip. The board has a 128×64 (0.96 Inch) OLED screen with an SSD1306 controller, 18650 battery charging circuit and a directional button.
The circuit board comes with a 10 pin header that you can solder onto it. The connections will provide one analog input and five digital inputs/outputs with interrupt/PWM/I2C/one-wire support. The back of the board has a battery holder that supports flat top 18650 batteries. Other characteristics of the board are:
- MCU: ESP-12E/F
- Board size: 102x30x20mm
- Voltage Input range: 5V-12V
- Micro USB connection
- Charge Current: 500 mA
- Battery overcharging and over-discharging protection circuit
Like the other ESP8266 based boards, it can be programmed with the Arduino IDE.
