The BBC micro:bit Go V1.3 (including V1.38 revisions) is a pocket-sized, programmable microcontroller designed to make learning and teaching electronics easy and fun. In 2026, the V1.x series remains a highly valued, cost-effective tool for STEM education, coding bootcamps, and rapid prototyping in business environments. 
Long Product Description
The BBC micro:bit V1.38 is a powerful, integrated development board powered by the Nordic nRF51822 SoC. It was developed through a partnership between the BBC and major tech companies to introduce students to the world of hardware and software. Despite the release of newer versions, the V1.38 remains a favorite for its simplicity, lower power consumption, and full compatibility with the massive ecosystem of micro:bit accessories. 
This “Go” bundle includes the essential components to start immediately: the board, a USB cable for programming, and a battery holder for portable projects. The board features a 5×5 LED matrix for visual feedback, two programmable buttons, and an array of onboard sensors including an accelerometer and a magnetometer (compass). Its most unique feature is the “Edge Connector,” which allows users to connect external components like motors, LEDs, and sensors using crocodile clips or specialized expansion boards. 
Key Features
  • nRF51822 Microcontroller: Features a 16MHz ARM Cortex-M0 processor with integrated Bluetooth Low Energy (BLE).
  • 5×5 LED Display: A 25-LED red matrix that can display scrolling text, numbers, and simple animations.
  • Programmable Buttons: Two tactile buttons (A and B) for user input and game control.
  • Onboard Sensors: Includes a 3-axis accelerometer for motion detection and a magnetometer for digital compass functionality.
  • Bluetooth Connectivity: Enables wireless communication with smartphones, tablets, and other micro:bits.
  • Edge Connector: 20-pin gold-plated connector providing easy access to GPIO, PWM, I2C, and power.
  • Universal Compatibility: Works with Microsoft MakeCode (Block-based), MicroPython, and Scratch
Usage Instructions
  1. Connecting: Plug the micro:bit into your computer using the included micro-USB cable. It will appear as a USB drive named “MICROBIT.”
  2. Coding: Open the Microsoft MakeCode or Python Editor in your web browser.
  3. Flashing: Write your code, click “Download,” and drag the resulting .hex file onto the MICROBIT drive. The yellow LED on the back will flash while the code is being transferred.
  4. Running: Once the LED stops flashing, your program will start automatically. Use the battery pack to take your project on the go
Q: What is the difference between V1.x and V2.x?

V1.38 (this model) uses an ARM Cortex-M0 and is strictly for visual/motion coding. V2.x adds a built-in microphone, speaker, and a more powerful processor. V1.x is often preferred by schools and businesses for its lower price point and stability for basic IoT tasks

Q: Can I use this for professional business prototyping?

Yes. The BLE (Bluetooth) and 2.4GHz radio capabilities make it an excellent tool for prototyping low-power wireless sensor nodes or internal communication tools before moving to custom PCB design.

Q: Does it support the latest version of MicroPython?

Yes, the V1.38 is fully supported by the official MicroPython for micro:bit editor

Q: My computer doesn't recognize the micro:bit. What should I do?

Ensure you are using a “Data” USB cable (the one included in the Go kit is a data cable). If it still doesn’t appear, try a different USB port or update your computer’s USB driver

Q: Is it safe for children to use alone?

The micro:bit is designed for users aged 8 and up. For business or educational purchasing, please note that the board has exposed circuitry; it should be handled with clean hands and kept away from metallic surfaces that could cause a short circuit

Q: Can I purchase this in bulk for a school or company?

Yes. We offer tiered pricing for educational institutions and corporate training departments. Please contact our sales team for quotes on orders of 50 units or more
