Introduction --------------- In the education market, micro:bit boards are becoming more and more popular. However, it is not easy to test a single micro:bit board with other sensor modules. Hence, we have specially designed this micro:bit T-type expansion board. Micro:bit T-type expansion board splits all the IO ports on the board into pins with a spacing of 2.54mm (GND, 5V, 3V3, Signal), which is very convenient to connect with other sensor modules and electronic components. In addition, you can power the micro:bit board through the white DC port (DC 3V) or micro USB interface (DC 5V) on the expansion board. The expansion board is able to boost or converse the voltage. If it is powered by an external power 3V, it can output 3.3V and 5V voltages. .. _2.-Features: 2. Features ----------- - Input voltage: white DC port (DC 3V) or micro USB interface (DC 5V) - Output voltage: 3.3V or 5V - The IO ports of micro:bit is divided into pins with a spacing of 2.54mm - Dimensions: 64mm x 56mm x 18mm - Weight: 13.1g .. _3.-Pin-out: 3.

What is Micro:bit -------------------- Launched by British Broadcasting Corporation (BBC), micro:bit is a microcomputer development board designed for programming education for teenagers. Though it is just the size of a credit card, the board integrates many components, including a 5x5 LED matrix, 2 programmable buttons, an accelerometer, a compass, a thermometer, a touch-sensitive logo and a MEMS microphone, a low energy Bluetooth module and a buzzer. This built-in buzzer plays all kinds of sounds without any external equipment. Moreover, its sleeping mode lowers power consumption of batteries when the Reset&Power button is long-pressed. .. _1.1.-Micro:bit-V2-Board-Layout: 1.1.

Notes for the Application of Micro:bit V2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #. It is recommended to cover it with a silicone protector to prevent short circuit for it has a lot of sophisticated electronic components. #. Its IO port is very weak in driving since it can merely handle current less than 300mA. Therefore, do not connect it with devices operating in large current, such as servo MG995 and DC motor, or it will get burnt. Furthermore, you must figure out the current requirements of the devices before you use them and it is generally recommended to use the board together with a Micro:bit shield. #. It is recommended to power the main board via the USB interface or via the battery of 3V. The IO port of this board is 3V3, so it does not support sensors of 5V. If you need 5V, the expansion board is required to connect to an external power. #. When using pins(P3, P4, P6, P7 and P10) shared with the LED dot matrix, block them from the matrix. Otherwise, the LED may display randomly and the data about connected sensors maybe wrong. #. **Pin 19 and 20 can not be used as IO ports** though the Makecode shows they can. They can only be used for I2C communication. #. The battery port of 3V cannot be connected with battery more than 3.3V, or the board will be damaged. #. Forbid to operate it on metal products to avoid short circuit. Simply put, micro:bit is like a microcomputer which has made programming at our fingertips and enhanced digital innovation. .. _2.-Micro:bit-Driver: 2. Micro:bit Driver ------------------- Micro:bit is free of driver installation. However, in case your computer fail to recognize the main board, you need to install the diver. **Driver installation instructions:** Connect micro:bit main board to computer via USB cable. .. image:: ./media/A252.png :alt: Img In both MicroPython_Tutorial folder and MicroPython_Tutorial folder, we provide driver files.
