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..
Connection Diagram, Sample Code, Using Method and Resources are provided in our wiki page. Technical support is available via email or message..
Solder is very clean, everything is aligned nicely, all boards are well packed after function, voltage, current testing, protected in a beautiful box. Up to FCC and CE Standard: made from environmentally friendly components and materials..

Precise timing of a single person moving from the starting point to the end point.
Effective laser distance: 0-8m , Wireless communication distance: 500m.
Rated voltage and current: 5V 2A , Please use qualified power bank（The device needs three power banks）.
When testing at close range, please ensure that the laser sensor and the display screen are 2 meters or more away from each other to prevent co-channel crosstalk between the antennas and cause communication errors..
Simple operation, plug the power cord into the USB port of the power bank, tap the reset button on the side of the screen for 1s to reset and start using.

【High quality】 Each telephone line was selected after careful selection and testing, and has reached high quality standards..
【Convenient connection】 The length commonly used in office, the phone can be placed 25 Ft away from the wall phone jack..
【Widely used】 The handset cord with standard RJ11 plug can be used for telephones, fax machines, modems, answering machines, etc..
