#79 GPRS/GSM and GPS in one cheap module: The A7 from AI-Thinker HD

In this video, I do a first test with this brand new module. It is well suited to build GPS trackers for logistics applications. Together with an ESP8266, an ESP8285, or an Arduino Pro Mini you can build such a tracker for less than 15 dollars. There is also a small introduction into antennas.
