Specially designed for Microbit board. This kit includes a keyestudio sensor shield fully compatible with micro bit and other commonly used 37 kinds of sensor modules. It's compatible with both microbit v1.5 and v2, microbit board not include!.
Designed to learn electronics programming. Great hands on STEM kit to get started with the micro bit. The product needs to be debugged before use, such as an LED display module. Please use an external power supply and debug the backlight brightness..
The kit gives 37 kinds of common sensors, such as Digital LED Module, Analog Temperature Sensor, Photocell Sensor, Ultrasonic Module etc, allow you make a lot of interesting projects like Traffic Light, Magnetic Check, Temperature Test, Joystick Test, Photo-interrupter Test, Alcohol Detection and so on..
We have detailed tutorial( included introduction, wiring diagram, test code, driver installation, Example Projects...... Step by step to explain how to use on our wiki page..
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..

output voltage range is DC 0.5-30V, can be arbitrary adjustable.
output current can be 3A for long term use, if enhance heat dissipation, it can reach 4A.
max output power is 35W, if enhance dissipation, it can reach 50W.
LCD displays input/output voltage, output current/output power/output capacity/output time.The module can be set to ON/OFF by default.
Safe Protection: the module is with Anti-reverse connection protection of input end, so that it will not burn out when there is reverse connection.Anti-backflow protection at the output end. No need to add anti-backflow diode when charging. Multiple software protection mechanisms are available, and the protection threshold is adjustable. When the working parameters of the module exceed the protection threshold, the output will be automatically turned off.
Application: the volt conversion board can be used as an ordinary buck/Boost module with over-current protection.
used as a high-power LED constant current driver module.
DIY a solar power controller, Battery Charging.
Output ripple is small and πfilter is available.Thick heat sink .Buck-boost Integrated.
