This product is a low-cost, high-performance microcontroller development board equipped with a 240MHz dual-core processor. In a small form factor, it is equipped with a 1.3-inch 262K color LCD screen, a lithium battery charging chip, a six- sensor (three- accelerometer and three- gyroscope), RGB lamp beads, and a Wi-Fi or Bluetooth antenna, making it suitable for development and embedding applications into products. Equipped with ESP32-S3R8 high-performance Xtensa 32-bit LX7 dual-core processor, with a main frequency of up to 240MHz Supports 2.4GHz Wi-Fi (802.11 b or g) and Bluetooth 5 (LE), with onboard antenna Built-in 512KB and 384KB ROM, stacked with 8MB PSRAM and external 16MB Flash Use Type-C interface, no need to worry about plugging in the right or wrong direction Onboard 1.3-inch LCD screen, 240x240 resolution, 262K color, can clearly display color images. Built-in ST7789V2 driver chip, using SPI does not occupy too many interface pin resources. Onboard QMI8658 six- inertial measurement unit (3- acceleration, 3- gyroscope) can detect motion posture and expand applications. Onboard 3.7V MX1.25 lithium battery charging and discharging interface. Lead out 13PIN 2.54mm pitch GPIO interface, can be used for external devices and debugging, flexible configuration of peripheral functions. The product appearance and printed words depending on the batch, but this does not affect use.
