I'm interested in creating a GPS tracker device that will connect to my server using either TCP or MQTT. To achieve this, I'm considering using a main chip like the ESP8266, ESP32, or mega2560. Additionally, I'll need two other chips or modules: one for GNSS/GPS and another for the SIM data connection.
My goal is to achieve accuracy comparable to the Chinese GPS trackers available on AliExpress. Can you recommend specific components or parts that I should consider for this project?
I've looked into Quectel and Simcom, but there are numerous options available, and I'm unsure which ones offer the best combination of performance and cost-effectiveness.
If anyone has experience working with these components, I'd greatly appreciate any insights or recommendations you can provide.
here is a gps tracker that i have home maybe u can see what they used
