Product Features
This product is a high-performance, highly integrated microcontroller development board designed by Waveshare. In a small form factor, it is equipped with a 1.75-inch capacitive high-definition AMOLED screen, a highly integrated power management chip, a six-axis sensor (three-axis accelerometer and three-axis gyroscope), RTC, a low-power audio codec chip, an echo cancellation circuit and other peripherals, making it easy to develop and embed 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/g/n) and Bluetooth 5 (LE), onboard antenna
- Built-in 512KB SRAM and 384KB ROM, stacked 8MB PSRAM and external 16MB Flash
- The Type-C interface improves user convenience and device compatibility
- Onboard 1.75-inch capacitive touch HD AMOLED screen, 466 × 466 resolution, 16.7 M colors, can clearly display color images
- Built-in CO5300 driver chip and CST9217 capacitive touch chip, using QSPI and I2C interface communication respectively, without occupying too many interface pin resources
- Equipped with dual digital microphone array, it can implement audio algorithms such as noise reduction and echo cancellation, suitable for accurate speech recognition and near-field/far-field voice wake-up applications
- Onboard QMI8658 six-axis inertial measurement unit (3-axis acceleration, 3-axis gyroscope) can detect motion posture, step counting and other functions
- Onboard PCF85063 RTC chip, connected to the battery through AXP2101, to achieve uninterrupted power supply, and reserve a backup battery pad to ensure that the RTC function continues to work when the main battery is replaced
- Onboard PWR and BOOT two customizable side buttons, convenient for custom function development using buttons
- Onboard 3.7V MX1.25 lithium battery charging and discharging interface
- Onboard 8-pin 2.54mm pitch female header, leading out 3 GPIOs, 1 UART, reserved I2C and 3 expansion IO pads, can be used for external devices and debugging, flexible configuration of peripheral functions
- Onboard Micro SD card slot for flexible storage expansion and fast data transfer, suitable for data logging and media playback, simplifying circuit design
- AXP2101 is used to efficiently manage power, support multiple voltage outputs, integrate charging and battery management functions, and optimize battery life
- The AMOLED screen has higher contrast, wider viewing angle, richer colors and faster response time, which provides better visual effects, slim design, low power consumption and flexibility.
