Please let us know the Major difference between MC20 & MC60 GSM module.
Also want to know, can we use MC20 outside China?
In dec’19 forum reply MC20 doesn’t have overseas certificates.
Indeed, MC20 is for China, MC60 for the rest of the world.
It’s to make certification less complex.
Difference in HW is, they have UART RX and TX inversed to make a difference.
