Great product

I've baught the IO extension board at Aliexpress store. I was satisfied with the quaility of the board related to it's price. The board is a good augmentation to microbit's v1 capabilities. It is worth to mention that technical support is very fast and useful.

Although small, it is very useful.

I purchased 20PCS for experimental courses on STEM classes. The quality is very good. The students have used it many times and the effect is still very good.
I plan to buy another 30PCS next week for use by local programming education institutions.

I believe that the product quality on Yahboom official website is guaranteed.

  • My dvr has broken, so I decided to recicle some pieces, one of them a12vdc vent. I would like to connect it to the basic bit board and write some code in phyton with the mu editor to read temp and send pwm value to move the vent. Can I connect it directly to the basic bit board pins (althouth i can not give more than 5 or 3 v to the vent). Second If I have a 12v batery like the ones it can hold the superbit board in order to reach the maximum rpm of the motor's vent, what circuit or plate I should place in between to ensure proper current to the vent but at the same time protect basic and microbit boards. Also please confirm if this also aplies to the red dc motors available from Yahboom.
