So I've stumbled on this on drive2.ru a while ago so I figured I would share it here too. How to make a diy dragy like 10 hz gps based 0-100 etc. measurement device.

You will need:
- a NodeMCU or Wemos D1 mini
- Neo-7m (or 8M)

Here is the connection diagram for them:

1.Download the latest firmware and extract it to a folder that you gonna find easily for example C:\D2Logic -> https://drive.google.com/file/d/1AcVPMBQ3y1YLDn2kr-GJtWbNWbkmYU2_/edit
The password is 12345678

2.Download Python and install it if you dont have it yet, and add it to PATH -> https://www.python.org/downloads/

3.Install ESPtool from python to flash the board, open CMD and type : python -m pip install esptool

4.After that plug the esp board in and check what com port its configured to then flash the firmware on it using esptool, for example:
esptool.py --port COM3 write_flash 0 C:\D2Logic\D2LogicV1.bin

Done. Go to 192.168.1.1 once the device is powered and you should be able to use the program once it finds the satellites. There are multiple upgrades one could do to this for example, put it in a case, make it battery powered if you dont want it wired. One thing to remember is try to have to gps antenna pointed at the sky for best reception :)
Good luck.
