He conectado la magicianbit con alimentación de 9 v, y las conexiones i2c, están bien.

No se mandan datos a la lcd.

In

[https://uk.robotshop.com/products/dagu-microbit-expansion-board-magicianbit](https://uk.robotshop.com/products/dagu-microbit-expansion-board-magicianbit)

it says “The power input interface of this board is designed to accommodate a voltage range from 6.4 to 8.4 V”. So connecting 6 x AA (maybe \> 9V) may not be advisable.
