MakerHawk A7 GSM GPRS GPS Module 3 in 1 Module Quad Band GSM/GPRS IPEX Antenna DC 5-9V Support Voice Short Message for Arduino STM32 51 Microcontroller MCU

Yet to get this working but it could be my lack of knowledge. Included documentation is poor and am yet to find a function to allow Sketch to build without an error. Product description and PIN labelling poor as well. Seems to be a solid enough piece of hardware, just struggling to get it to do what it says on the tin.BUYER BEWARE: Description states 3m GPS and 2m GPRS antenna included - It is NOT. Actual lengths are those shown in imagery, about 6cm and 2cm respectively.

This device is badly labelled. Some of the pins labels are barely legible.There is no documentation supplied and when I enquired I received a list of Hayes AT codes.I only got any sense of the device when I looked up the Ai Thinker A7 processor.Many of the I/Os are 3.3V not 5V so it is not directly Arduino compatible.Recommend that the supplier provide a document showing recommended Arduino connections and sample sketches with the device.
