BBC Micro:Bit - Microcontroller - V2.21

BBC Micro:Bit - Microcontroller - V2.21

Unleash your potential and get creative with code, electronics, science and technology. Anything is possible with the BBC micro:bit!

Overview:

• ideal for beginners
• designed for the education sector
• has a 5*5 LED matrix
• has a magnetometer
• has a 3-axis acceleration sensor
• with Bluetooth BLE interface
• with two programmable buttons (push buttons)
• with 20 I/O pins

Integrated sensors: Thanks to an impressive array of integrated sensors, the micro:bit is in tune with its environment. The micro:bit can detect movement in 3 directions, so you can tackle projects like motion-triggered alarms, turn the micro:bit into a tilt controller and much more. It has an integrated compass and can also detect changes in temperature and light. With the microphone, you can monitor sounds that can be used to trigger other events or displayed on the LED matrix.

Buttons: The micro:bit has two user-programmable buttons. Turn things on and off or use them to move around in games. The possibilities are endless. V2 of the micro:bit also features a front-mounted touch logo that is part sensor and part button.

Light and sound: The micro:bit V1 and V2 both have an LED matrix display. This display is arranged in a 5 x 5 grid, is fully programmable and can be used to display text, numbers or images. Create badges, status indicators and more. It also has an integrated microphone that can be used for code that responds to sound.

Wireless: The micro:bit offers two different forms of wireless communication, Bluetooth and radio. In microbit V2, Bluetooth has been upgraded from Bluetooth 4.0 to 5.0. Bluetooth. Allows the micro:bit to communicate with other Bluetooth devices such as phones, tablets and even PCs. The radio module enables the micro:bit to communicate with other micro:bits in the vicinity via radio waves.

Edge connectors: The micro:bit has 25 pins; 4 dedicated GPIO, PWM, i2c, SPI, power supply and also 3 ring pins for connecting alligator clips/banana plugs. Notched in V2 for easier connection via alligator clips. I2C is now a dedicated bus as opposed to the shared bus of V1.

Power supply: You canpower the micro:bit in three different ways : via the USB port, the JSTbatteryconnectorand the 3V pad on the edge connector. In V2 we see an additional on/off switch and an LED power indicator. The updates in V2 also mean an increase in the amount of current available for accessories, which has increased from 90 mA to 200 mA.

Coding: You can useMakeCode for Blocks, JavaScript and Python to utilize all the features common to both versions of the BBC micro:bit: Any program that could run on a micro:bit version 1 can be rebuilt to run on V2. The editors support both versions simultaneously for features common to both boards.
