ESP32-Adulo-Kit is a new WiFi Bluetooth dual-mode development board. It uses a PCB on-board antenna and the ESP32-A1S module on the board, which can work independently as a minimum system.

  • Using ESP32 to integrate Wi-Fi, traditional Bluetooth and low-power Bluetooth (BLE Beacon), with two high-performance 32-bit LX6 CPUs, using a 7-stage pipeline architecture, the main frequency adjustment range is 80 MHz to 240 MHz.
  • On-chip Sensors: Hall sensor,temperature sensor, etc.
  • Fully compliant with WiFi 802.11b/g/n/e/i and Bluetooth 4.2 standards, it can be used as a master mode to build an independent network controller, or it can be used as a slave to run on other host MCUs to add networking functions to existing devices.
  • ESP32-Audio-Kit can be widely used in various loT scenarios, suitable for home smart devices, smart speaker solutions, children's story machines, etc. It is an ideal solution for loT audio applications.
    Ultra-full-featured 802.11b/g/n WiFi + BT/BLE SOC dual-mode development board.
