Added GPS to my Lilygo T-Deck lora devices - working perfectly

Great little GPS module. I installed these in 2 T-Decks running Meshtastic. Received good satellite reception. I switched out one of the antennas for an external one and I'm getting 21+ sats now.

I needed a small GPS module for an ESP32 project's clock circuity. I wasn't looking for the GPS coordinates, just a precision time source. With the help of an online AI interface, I quickly had the code I needed and it was up and running within minutes! It only required 4 wires to connect to the ESP32. I decided to check it's latitude and longitude capabilities and was surprised to see it resolve about a 3 foot move of the module on my workbench! This module was a great value and met my needs perfectly!

I was working on a project comparing location fixes by the different satellite constellations. This gps module was included in my testing. I pasted the GPS stream into a chatgpt session and it commented back that the signal was decoding BD signals better than any of the other expensive modules that I was using from various vendors. I suspect that this one is tuned for the BD consultation. It was quick at getting a fix and I had no issues pulling down the data stream over UART as expected. It is a nice, small, inexpensive module that gets the job done for any project needing a location fix.

I used this to add GPS to a Lilygo T-Deck and apart from one head scratcher, it’s been easy and great. The TX and RX needed to be inverted for the T-Deck. I don’t know why exactly, but when I sorted that all out, it’s picks up multiple satellites quickly and reliably.
