Equipped with an ESP32-S3FN8 dual-core processor (up to 240MHz) and 8MB Flash, providing powerful computing capabilities to meet the demands of complex programs. Integrates an ES8311 audio decoding chip, a high signal-to-noise ratio MEMS microphone, an NS4150B power amplifier chip, and an 81W speaker, achieving high-quality audio capabilities across the entire "acquisition-decoding-playback" chain, suitable for voice control and interactive project development. Equipped with a 3.5mm audio jack for easy audio output. Features a 1.44-inch LCD screen (240x135px resolution). Combined with a comfortable 56-key keyboard (160gf key pressure, smooth feel). Built-in IR infrared emitter. Supports multimodal interaction: screen display + button input + infrared control. Excellent human-computer interaction experience; operation can be completed without additional external interaction devices. Supports multiple satellite systems including GPS, QZSS, BDS (BeiDou), , and GLONASS, with positioning accuracy <1.5m (CEP50). Supports cold in just 23 seconds and warm in 1 second, and can still quickly acquire high- location even in areas with weak signal. Meets the needs of scenarios with high requirements for positioning accuracy and response speed, such as in-vehicle navigation and smart cities. Supports mainstream development platforms such as , UIFlow2, ESP-IDF, and PlatformI0, allowing both beginners and professional developers to quickly get started. Efficiently completes prototyping and implementation for "rapid functional verification, embedded systems, and IoT projects."
