ESP32-C3 0.42 Oled

ESP32 C3 0.42inch Oled Lcd Super Mini Development Board Wifi Bluetooth Type-C Usb

160Mhz 4MB Flash 400kb PSRam MicroPython Arduino Iot ADC I2C SPI UART

When the product is powered from usb, a text appears on the screen indicating that wifi is being searched for. No additional documentation is included with the product. No additional software support will be provided.

     It is a development board that can perform wireless communication and is arduino compatible. The Esp32C3 integrated circuit is used in the module. A 0.42” oled lcd is located on the board. It can be programmed via the Type C usb port. It draws power via the Usb port. It can operate with an external 5V supply.

     It has 13 digital input output pins. There is a reset and boot button and 1 user led on the board. There are empty header slots for connection on the board edges. In addition, these pads have a design that can be soldered from the board edge onto a lower board. By creating a low height on the lower board, you can make projects that fit into very small enclosures.

     It can be programmed via Micropython. It can also be programmed via the Arduino IDE. It is used in IOT, wireless internet control applications, various sensor readings, and similar internet based projects.

     When you plug it into the pc, 1 com port and 1 jtag device automatically appear in the system. If you press the reset button while holding the boot button and then release the boot button, the product enters programming mode.
