[Introduction]：ESP32-S3-MINI-1 is a universal Wi-Fi + low-power Bluetooth dual-core wireless module, equipped with Espressif ESP32-S3 chip. In addition to rich peripheral interfaces, the module also has powerful neural network computing capabilities and signal processing capabilities, and is suitable for a variety of application scenarios in the AIoT field, such as wake word detection and voice command recognition, face detection and recognition, intelligent Home, smart appliances, smart control panels, smart speakers, etc. This dual-core Bluetooth WiFi module uses a PCB onboard antenna. Wi-Fi and Bluetooth coexist and share the same antenna.
