What is the difference between M26 and M66?
The model is M26 in China and M66 for overseas export
The m26 module and the m66 module are the same. Can it be used instead of the m26 module?
YES,However, you need to pay attention to whether the main serial TX/RX is consistent
In a study that will be done by paying attention to the pin connections, what is the possibility of it working by replacing the M26?
Others may not need attention
Sorry, I don’t have a corresponding entity of M25 module
