Development ESPrtk + F9P C099 – Tadashi Hazawa.

Build the first Dev circuit board.

Tadashi Hazawa (羽澤 正) is interested in ESPrtk’s solution and intends to use ESPrtk in his project. 👌🥰

A test board was built right away . 🇯🇵 🇻🇳

It includes ESP32 (ESPRTK), F9P C099 (GNSS) , OLED (Display SSD1306) and a 5V-3.3V voltage converter circuit.🚀🛰🛰 🛕⛩

He is trying to build a rtk Base station with ESP32 (ESPrtk NTRIP Server) and F9P , combined with VRSC software.

Tadashi Hazawaand the ESPrtk Dev team did various installations to test and get some results.

The ESPrtk software also needs to be updated to be usable and synchronized with the VRSC application.
