Onboard Multiple Interfaces: Onboard QMI8658 6-axis IMU (3-axis accelerometer and 3-axis gyroscope) for detecting motion gestures, counting steps, etc. Onboard PCF85063 R-T-C chip with reserved SH 1.0 R-T-C ba tte -ry header (supports charging) for R-T-C function requirement. ^^ Onboard RST button and programmable BOOT button for easy custom function development. Onboard 3.7V MX 1.25 Li -thi um ba tte -ry recharge/discharge header. Onboard TF card slot for external TF card storage of pictures or files. ^^ Onboard USB Type-C port for power supply, program downloading, and debugging, more convenient for development use. Onboard UART and I2C SH 1.0 4PIN connector, reserved 2 14PIN 1.27 mm pitch headers, adapting multiple GPIO interfaces. ^^ Adopts AMOLED screen. The next-generation display technology, compared to those traditional LCD displays, the AMOLED screen features precise light-control capability, representing more delicate colors, more picture details, and more vivid video image. ^^ Currently provides two development tools and frameworks, Arduino IDE and ESP-IDF, providing flexible development options, you can choose the right development tool according to your project needs and personal habits.
