Best Keyestudio Single Board Computers in 2026

PERFECTLY COMPATIBLE with IDE Software: a nice upgrade to the r3 controller which will allow more complex programs and projects to be done

RIGHT OUT OF THE Box: uses the official ATmega IC instead of CH340G, no driver problem

EXCELLENT QUALITY: The build quality is good with straight headers and good soldering. It comes with instructions on downloading and installing a driver on Windows machines. They are well packed in a nice box.

Please NOTE: Open the Arduino IDE, you’ll need to click the “Tools”, then select the Board that corresponds to your Arduino. If you don't choose the correct development board type, it will cause the compilation to fail to transfer. So this is a place that needs special attention.

The keyestudio Leonardo is a microcontroller board based on the ATmega32u4，It has 20 digital input/output pins (of which 7 can be used as PWM outputs), 12 analog inputs, a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.

The Leonardo differs from other boards using separate USB-Serial chip in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor.

Specially designed for Microbit board. This kit includes a keyestudio sensor shield fully compatible with micro bit and other commonly used 37 kinds of sensor modules. It's compatible with both microbit v1.5 and v2, microbit board not include!

Designed to learn electronics programming. Great hands on STEM kit to get started with the micro bit. The product needs to be debugged before use, such as an LED display module. Please use an external power supply and debug the backlight brightness.

The kit gives 37 kinds of common sensors, such as Digital LED Module, Analog Temperature Sensor, Photocell Sensor, Ultrasonic Module etc, allow you make a lot of interesting projects like Traffic Light, Magnetic Check, Temperature Test, Joystick Test, Photo-interrupter Test, Alcohol Detection and so on.

Particularly design this keyestudio sensor expansion board V2 for micro:bit. breaks out all the PIO ports on the micro:bit control board into 3PIN interface (GND, VCC, Signal), easy to connect it with other sensor modules.

Extending some commonly-used serial communication interfaces into pin or female headers with 2.54mm pin pitch, such as I2C and SPI communication pins.Allows communication between micro:bit control board and other communication devices.

Two kinds method to power the micro:bit board, through a black DC jack (DC 7-9V) or a mciro USB port (DC 5V) on the shield.

This sensor kit comes with 37 basic sensors and modules, which is good for learning basic knowledge about sensors. The main controller is Not Included.

It comes with detailed tutorials which include pictures and code and 37 projects, explained step by step. Note we provide arduino tutorials, without Raspberry Pi tutorials.

Each module has 3-4 pins broken out that make it easy to plug into a solderless breadboard or hook up to with DuPont wires. They are intended to be used with the Arduino platform, but can also be used with the Raspberry Pi platform as well.

Bright and clear display- white texts on Blue backlight, adjustable contrast

Built with IIC/I2C interface to save 5 IO ports(the original 1602 LCD needs 7 IO ports to be up and running)

Plug and play; Easy to use with Arduin Liquid Crystal Library; Easy to connect to a Raspberry Pi

Keyestudio MEGA ProtoShield makes it easy to design circuits and solder electronics. All the pads are tinned and easy to solder to.

The extra GPIO pin header on the right side is left empty making easier to install one according to the user's preference.

Be able to attach a Mini breadboard to make various circuit experiments. You can weld elements on the shield's prototyping area or connect circuits with tiny breadboard.

This expansion board can directly stack on the controller R3 board and can drive up to 16 servos

Uses I2C input, just occupy A4 and A5 interface on the control board

Contains PCB double sided holes, can direct to solder with components to build up prototyping circuits

It integrates 4-channel 5V relay module, and is fully compatible with R3 control board.

The 4-channel relay module shield is active at HIGH level.

Relay Terminals: high-power, high-current high voltage can be connected to the device.

Micro bit controller V2.21 is included！onboard comes with Bluetooth, accelerometer, electronic compass, three buttons, 5 x 5 LED dot matrix, mainly used for teens programming education.

Specially designed this starter kit which includes common used resistors, LEDs, sensors, LED segment display and more to get you started 18 interesting projects at least.

We have detailed tutorial( included introduction, wiring diagram, test code, driver installation, Example Projects...... Step by step to explain how to use in our wiki page.

Compatible with the open source development environment Arduino UNO R3 and Arduino IDE.

Microcontroller：ATMEGA328PB

USB to serial chip: CH340C

KEYESTUDIO UNO MAX kit contains a Max development board, acrylic boards, screws, copper bushes and a Type C USB cable.

The Max Control Board is an Arduino uno-compatible board, which isbased on ATmega328P MCU, and with a cp2102 Chip as a UART-to-USB converter.

It integrates three LEDs, two 6812RGB LEDs, two button switches, a buzzer, a microphone sensor, a light sensor, and an 8*16 dot matrix.
