GPS内蔵コンパスの変更について:
HMC5883L -> QMC5883

https://belchip.by/sitedocs/10882.pdf によると:

QMC5883Lis made by a Chinese company, they get the production authorization of HMC5883L
from Honeywell, and rename it QMC5883L

また、https://surtrtech.com/2018/02/01/interfacing-hmc8553l-qmc5883-digital-compass-with-arduino/ によると:

But actually it’s not a fake but it’s the QMC5883 which is a similar module but cheaper and not stable, and in this post I’m using one of them.
