Everyone who had experience working with the mainstream SIM800L EVB module knows too well how difficult it can be to make the module work. There are two main reasons for this difficulty. 1. You have been sent an untested and defective board ( unbelievably common) 2. You are using a power DC converter circuit not suited for the SIM800L module.
e-Gizmo SIM800L was made to save you from the above mentioned troubles, so that you can concentrate more in writting your codes, instead of troubling yourself trying to make your hardware work.
