Teyleten Robot ATGM336H GPS+BDS Dual-Mode Module Flight Control Satellite Positioning Navigator Replacement NEO-M8N NEO-6M for Arduino 2pcs

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 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.

Easy to install in the T-deck and other compatible radios. Only 4 connections: Vcc, gnd, TX and Rx. Must be soldered and works with most ESP32 radios.

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.

The media could not be loaded. I’m using these with my esp32 to make a cheap wardriver that is connected to my android. Used the TinyGPS library examples and expand from there. Very easy to hook up after soldering! Will buy more.

The media could not be loaded. In my experience, this GPS/GNSS module works the best for the T-Deck conversion to the LilyGo T-Deck Plus.Once I soldered the module to the T-Deck’s Grove port on the board, I went to Meshtastic’s website to program it to the LilyGo T-Deck.I went outside, and in about a minute or so, I locked up 15 satellites. I pulled up my coordinates, and it was spot-on accurate.I walked about 8 miles round trip, through Manhattan (NYC), and the module locked-on and held its connection through the entire 8-mile walk.I bought two more modules, which will arrive today, 30-Dec-2024. I’m building a T-Deck Plus for my girlfriend, using this module.I like the red LED light, which indicates the module is on and active.Check 6!/s/ Alfonso Faustino

These worked straight out of the box with the esp32 that I purchased. They pick up states fast, and I ping about 12 with them. They are cheaply priced and the soldering is super easy.

I dropped these in on my LillyGo T-Decks by soldering wires directly instead using the included pins. No issues there, just make sure you cross over the RX and TX as needed.
