This simplest Agro GPS receiver for parallel driving app is better than the first one because it operates at free L5 satellites for decimeter accuracy. Just connect 4 wires between modules and flash module firmware. Firmware is free and open-source.

For decimeter accuracy, the TAU1201 module is used. ESP32 controller with built-in bluetooth low energy (BLE).
You can build it yourself and use it with my parallel driving app.
