K210 comes with dual-core processor chip with independent FPU, 64 bits CPU bit width, 8 MB on-chip SRAM, 400 adjustable nominal frequency, and double precision FPU supporting multiplication, division and square root operation. Besides, Maixduino AIDevelopment Boardis equipped with neural network hardware accelerator KPU, voice processing unit (APU), programmable IO array (FPIOA/IOMUX) and Fast Fourier Transform Accelerator. In the AI processing, K210 can perform operations such as convolution, batch normalization, activation, and pooling. At the same time, the pre-processing of voice direction scanning and voice data output can also be performed.
The on-board wireless module of the product is the ESP32-WROOM-32 with dual-core ESP32 Xtensa LX6 processor, supporting 2.4GHz 802.11.b/g/n WiFi 4 and Bluetooth 4.2 LE connectivity. Besides, it has DVP camera connector, LCD display connector, built-in MEMS microphone, TM8211 I2S audio DAC, 3W power amplifier, USB 2.0 Device type C port for powering and programming via dual channel CH522 chip to support for both K210 and ESP32, Arduino UNO compatible headers with digital I/Os / PWM, I2C, UART,آ and 6 analog inputs.
Application: smart home(Robotic vacuum cleaner and Smart speaker), medical device, industry 4.0, agriculture and education.
Maixduino Development Board and OV2640 Camera are included in the package.
Note:The shape and pins are compatible with Arduino UNO R3 but the voltage level is not compatible, which requires great attention, otherwise the board can be damaged. Maixduino supports 3.3V and 1.8V levels, and the pins are divided into several BANKs, each BANK can be set to a voltage of 1.8V or 3.3V by software, However, these pins are not 5V tolerated. Therefore, when using the peripheral device of Arduino, be careful not to short the 5V to the pin or RST (1.8V) pin.
