Overview

• The Xmini-C3 development board was designed and open-sourced by Xiaozhi AI creator Xia Ge. It uses Espressif Technology’s ESP32-C3 as the main control chip, with an onboard 16MN0RFLASH. The audio uses ES8311 audio decoding and NS4150 power amplifier IC solutions. It uses a ceramic antenna and can run the latest version of Xiaozhi A1 smoothly and normally.
• Supports B0OT button wake-up (does not support offline voice wake-up)
• Supports automatic 0TA upgrade of the new version (16MFLASH)
• Supports continuous multi-round dialogues and interrupts the dialogue with the BOOT button.
• Supports 0.96-inch SSD13060LED display (monochrome/dual color), supports expression and status display (the subtitle version cannot be automatically updated for the time being, you can join the group and burn it yourself)
• Supports 3.7V lithium battery power supply and charging (battery power detection is not supported yet)
• Supports 3W-5W cavity speaker interface
• The expansion interface is 6Pin, two-way power supply and two 10 interfaces, supporting external I0 devices (to be developed)
