The development board is designed using the Al module + ESP32 module + bottom plate, with on-board Type-C interface and USB-UART circuit. Users can directly connect to the computer through the USB Type-C cable for development. It is equipped with 200W pixel camera, LCD, Mic, PA, TF card and other interfaces, and some IOs are drawn out, which is convenient for users to expand. In addition, the onboard ESP32 module supports WiFi and Bluetooth wireless connection, which can wireless transmission. The for Maixduino development board uses the M1 Al module as the core unit, which is powerful. The module has a built-in 64-bit dual-core processor chip and 8M on-chip SRAM, which is convenient for AI machine vision and hearing performance. A of built-in hardware acceleration units (KPU, FPU, , etc.) have a computing power of up to 1TOPS, which can implement machine vision/hearing algorithms for application scenarios, and can also voice direction scanning and voice data output preprocessing Work. Core: RISC-V Dual Core 64bit, with FPU Main frequency: 400MHz (can be overclocked to 600MHz) SRAM: Built-in 8M Power supply voltage: 5.0V@300mA (power supply current needs to be 300mA) Chip : FreeRTOS, RT-Thread, etc. Development environment: MaixPy IDE, PlatformlO IDE IDE, etc. Programming languages: C, C++, MicroPython Size: 60 x 88mm :PCB Colour: Black Package Contents: 1 x Development Board 1 x 2.4 Inch Screen 1 x 32G TF Card 1 x G4.4 Camera 1 x Microphone Array Only the above package content, other products are not included.
