It is built around an integrated ESP32-S3R8 core with 16MB Flash and 8MB PSRAM, and supports 2.4 GHz Wi-Fi wireless communication. The board incorporates a complete human-machine interaction system, including three programmable buttons, an audio system based on the ES8311 audio codec, a MEMS microphone with AEC echo cancellation, and a speaker driven by an AW8737A amplifier — enabling high-quality voice capture and audio playback. In terms of expanded functionality, the board integrates an SHT40 temperature and humidity sensor, RX8130CE real-time clock, microSD card slot, infrared emitter, two RGB LEDs, and an HY2.0-4P expansion interface. Combined with the M5PM1 multi-stage power management system and a 1250mAh battery, it enables long-lasting, low-power operation. Suitable for IoT and embedded applications such as electronic signage, voice interaction terminals, environmental monitoring instruments, and art display installations.
