It Started With a Hardware Limitation I have been using Quectel GNSS modules in my designs for a while. They are reliable, well-documented, and the support ecosystem is solid. But the module I had been using had one problem that I kept running into: no external antenna support . For most projects that is a minor inconvenience. For a marine vessel monitoring and control system , it is a non-starter. A vessel hull blocks sky view, antenna placement is critical, and the difference between a clean fix and no fix at all often comes down to whether you can mount the antenna where it actually has line of sight. An integrated antenna in a sealed enclosure below deck simply does not cut it. So I went directly to Quectel. The Conversation With Quectel I reached out through their official sample request channel. I was not expecting much — most component manufacturers have a standard process: fill out a form, wait, get a few uni...
After a long Que of waiting for Pi Zero,i have received it. The size of Pi Zero is very small and compact comparing to other versions of Pi. I am not going to give a review on Pi but since i like the Raspberry Pi. i would like to give some information on what i did to test its performance. For technical details go directly to raspberrypi.org. Raspberry Pi Zero running RetroPie, just for a test. For testing purposes i installed OSMC and test as a media player and i am happy with the performance. Later i installed RetroPie and check how the new hardware performed. RetroPie is cool that it enables to play almost all the retro games that we played when we were young. :) RetroPie running I am not interested of GUI so kept aside all the i candy parts and focused on controlling GPIO and runing python scripts and bash script for external hardware communication. Overall what i can say is the waiting for Pi Zero is not time wasting, Pi Zero is better and faster. Thumbs...
