My newbit board, compatible with microbit. I add buzzer, so it may play music directly. And I also add a vibrator, provide feedback in play games.

That looks great. I was thinking about following the reference design myself, but first I'm waiting for the nrf51822 dev board to try flashing MicroPython on it. Did you have any problems with it?

It works fine, I have test it in micropython, python Editor, javascript block editor.
You may using IOS app to download with bluetooth , but android app always fail.

The problem in microbit is micropython version is too old, and paste mode is not work. And free space in flash is only 8KB.

Interesting. I see the micropython.cn community is comercializing it already for 100 Yuans in taobao, which might be around 13,5 euro...

Have you considered using more LEDs (with a led matrix driver chip, because then you don't have enough pins) for the display, so that you can actually display Chinese characters on it? We had a Korean user here trying to display Hangul in 5x5, but it didn't work very well...

Smallest Chinese fonts is 12x11 matrix, it need more space to place LEDs, and will not compatibity with microbit code. I consider add a 128x64 OLED module, include a font chip, using SPI bus.
