The Maix Bit is a compact AI development board powered by the Kendryte K210 dual-core RISC-V processor. With 8MB of on-chip SRAM (6MB general purpose + 2MB AI dedicated), a built-in neural network processor delivering hundreds of GOPS, and MicroPython support, it's a powerful and affordable platform for edge AI, machine vision, and IoT applications.
The board is compatible with most OpenMV algorithms via the MaixPy firmware, giving you access to a rich ecosystem of computer vision tools. It includes a DVP camera connector, LCD interface, onboard MEMS microphone, TF card slot, and all GPIO pins broken out to standard 2.54mm headers — all on a board just 53.3 × 25.4mm.

Jargon buster
Plain-language definitions for the technical terms used above.
- FPC
- FPC stands for flexible printed circuit, a flat flexible cable or connector style often used where space is tight. It matters because this breakout needs the correct pin count and pitch FPC cable to connect reliably to the display or high-speed interface.
- FPU
- A floating-point unit is hardware inside a processor that speeds up calculations with decimal numbers. This helps when projects use maths-heavy tasks such as motion sensing, filtering sensor readings, or audio processing.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- JTAG
- JTAG is a hardware debugging and programming interface used to inspect and control chips at a low level. It matters for advanced development because it can help diagnose firmware problems that are hard to see through normal serial output.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- MEMS microphone
- A tiny microphone made using micro-electromechanical systems, the same style of miniature manufacturing used in many phone sensors. It lets the board detect sound without needing an external microphone, which is useful for noise-reactive projects and simple audio input.
- MicroPython
- A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
- OV5640
- A specific camera sensor chip that captures still images or video data for a microcontroller or processor. The exact sensor matters because code examples, wiring, resolution, autofocus support and data format depend on the chip model.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- RISC-V
- An open processor architecture used inside some modern microcontroller chips. It matters because it affects the software tools, performance, and low-power features available for developing projects on the board.
- SRAM
- Fast temporary memory used by a processor while a program is running. More SRAM helps with projects that handle larger data buffers, networking, displays, or more complex code.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
