How to compare the sensors used on the new and old versions of microbit, this article introduces in detail the corresponding analysis and solutions to this problem, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The hardware of microbit has been quietly upgraded to v1.5. I just got a new version of microbit, so I'll give you a simple comparison to make it easier to understand its changes.

The new version of microbit is not much different from the old version, the most important thing is that the sensors (acceleration and magnetic field sensors) have been replaced. After the shutdown of NXP's MAG3110 magnetic field sensor, the microbit has now been replaced by ST's LSM303A sensor. The new sensor is a two-in-one sensor, which integrates acceleration and magnetic field sensors inside a chip, but it turns out to be two independent sensors. In addition, in the source program of microbit, I also see the FXO8700 part of NXP, and I don't know whether there will be hardware versions of multiple sensors in the future. However, it is the same for users, because the data reading from the sensor has been converted by the underlying firmware, the values read are similar, and there will be no difference in use.

Note:

The new version of microbit requires the new version of makecode and the new version of python firmware, which are compatible with the old and new versions of microbit hardware, while the old versions of makecode and python firmware only support the old version of microbit.

Comparing the old and new versions of bit, on the left is the new version.
