Micro:bit

Two micro:bits. Notice that the v2 example on the right has small notches to distinguish it from v1.

The micro:bit is a small programmable computer developed for education and experimentation. It was created by the BBC to encourage coding and digital skills in young people.

There are two versions of the micro:bit: version 1 and version 2. Both versions are similar in many ways, but there are some key differences between the two.

v1

Overall, the micro:bit v1 is a small and affordable device designed for education and experimentation in programming and electronics. Its compact size, variety of sensors and input/output options, and wireless capabilities make it a versatile tool for a wide range of projects.

• Processor: 16MHz ARM Cortex-M0
• Memory: 16KB RAM, 256KB Flash
• Wireless: Bluetooth Low Energy (BLE)
• Sensors: Compass, Accelerometer, and Temperature sensor
• Input/Output: 5x5 LED matrix display, 2 programmable buttons, 3 analog input/output rings, 20-pin edge connector for additional accessories
• Power: Micro USB connector for power and programming, or 2 AAA batteries (not included)

v2

Compared to the micro:bit v1, the v2 has a more powerful processor, more memory, and additional features such as a microphone, speaker, touch-sensitive logo, and capacitive touch sensor. These enhancements make the micro:bit v2 more capable of handling complex tasks and enable more advanced projects and experimentation with sound and touch-based interactions.

• Processor: 64MHz ARM Cortex-M4
• Memory: 512KB RAM, 2MB Flash
• Wireless: Bluetooth Low Energy (BLE)
• Sensors: Compass, Accelerometer, and Temperature sensor
• Input/Output: 5x5 LED matrix display, 2 programmable buttons, touch-sensitive logo, capacitive touch sensor, 25-pin edge connector for additional accessories
• Sound: Speaker and microphone
• Power: Micro USB connector for power and programming, or 2 AAA batteries (not included)

Despite these differences, both versions of the micro:bit are great tools for learning to code and experimenting with electronics. They are easy to use, affordable, and come with a range of resources and tutorials to help beginners get started.
