The Maix Bit AI development board utilizes the K210 AI chip based on the RISC-V architecture. The K210 features a dual-core processor with an independent FPU, a 64-bit CPU, 8 MB of on-chip SRAM, adjustable nominal frequency up to 400 MHz, and a double-precision FPU supporting operations like multiplication, division, and square root.
Within its compact dimensions of 53.3mm x 25.4mm, the Maix Bit AI development board integrates several key components. These include 128 Mbit high-speed Flash memory, a CH552 high-speed USB to Serial port chip, RGB LED, MEMS microphone, a 24-pin DVP camera interface, and a 24-pin 8-bit MCU LCD interface. The product emphasizes a RISC architecture, delivering high performance at an affordable price, with support for AI and MicroPython.
The MaixPy firmware, based on MicroPython, simplifies the integration of AI algorithms and conventional microcontroller operations. It is compatible with most OpenMV APIs. Purchasing the MAIX development board offers capabilities equivalent to a three-fold more expensive OpenMV board! Regular algorithms demonstrate 2-3 times the performance of the original STM32H7 version, while AI algorithms achieve over 1000 times the performance of the STM32H7 version of OpenMV. Yes, that's right—1000 times!
The kit contains the Maix Bit AI Development board along with a 2.4” LCD display and an M12 camera. The camera comes with a default 4mm focal length HD lens equipped with a 650nm infrared cut filter, and users have the option to change the lens themselves.
