① Simple ② Change life ③ Affordable

Easy to operate, whether in elementary school or university, very easy to start, with unlimited possibilities! | 90% of students say that micro: bit helped them realize that anyone can program | The cost is lower than most toys, and the price of a complete course is less than a laptop |
What is a micro: bit extension?
![]()
Bit is a self-developed expansion board that facilitates the use of Micro: bit motherboards, providing power for Micro: bit. The bit board integrates a Micro: bit interface socket, making the Micro: bit motherboard plug and play.
The bit expansion board is equipped with RGB color lights, buzzer, 2-channel motor drive, 8-channel servo drive, and infrared remote control light hardware circuit. Not only can it meet our daily development and learning needs, but it also reserves a large amount of IO for expanding sensors.
