Description

Keyestudio ESP32 Easy Coding Board is equipped with 520KB dynamic memory, 4MB flash memory and 240MHz dual-core processor to easily run a variety of real-time operating systems, like freeRTOS. Besides, its low-power Bluetooth and WiFi capabilities are excellent for wireless communication.

This board also integrates a variety of sensors on its board: The temperature and humidity sensor monitors ambient temperature and humidity in real time; The six-axis acceleration gyroscope obtains motions and acceleration; The ambient light sensor captures ambient light intensity; The SD card interface saves the detected data; The microphone detects ambient sound, and the buzzer plays music; Buttons A and B, 7 touch keys on the board can be used as switches; 5x5 RGB dot matrix displays numbers, letters and patterns with stepless dimming.

Therefore, it is widely applided to STEAM teaching, IoT, intelligent control projects, and a variety of DIY creative works.

ESP32 board is welded with gold-finger expansion pins, including all IO pins, 19 digital ports, 7 analog ports, I2C, UART and SPI interfaces.

This board is compatible with a variety of programming languages, including Arduino, MicroPython and graphical programming KidsBlock3.0, and development environment of multiple boards. It is suitable for users with different programming levels.
