## Article

This is the ESPrtk NTRIP Base + CORS project of Volodymyr Maslovskyi. He uses ESP32 DEV kit and PX1122R modules. Initially he had a problem with the hardware but then everything was resolved. Then he experimented with building NTRIP Base station with ESPrtk WIFI and Ethernet.

- App Build : NTRIP/MQTT RTK Base Station+Rover+CASTER

- ESP32 : ESP32 DEV KIT C Espressif ( [ESP32_WROOM_32U](https://esprtk.files.wordpress.com/2020/11/htb1sxjax5lxk1rjy0ffq6zydvxa6-copy.jpg) or [ESP32_WROOM_32UE](https://esprtk.files.wordpress.com/2021/09/esprtk-esp32-wroom-e-_-esp32-wroom-ue.jpg) CHIP)

- RTK GNSS: F9P or PX1122R

- Display: OLED SSD1306 0.96 inch or SH1106 1.3 inch( option !)

- Ethernet: W5500 ( option !)

- Power supply: 5V 2.5A Adapter

- Other: LED , Button, Switch , 2.4Ghz WiFi Antenna , GNSS RTK Antenna, RJ45 Etheret cable, Micro USB Cable , 3.3V Active Buzzer

### **Step 1 : Hardware connection – ETHERNET + Full standards.**

For RTK Basestation applications with up to several months or years of continuous uptime, we always recommend users to use the W5500 Ethernet module for their systems to ensure a stable 24-hour connection !.

In addition, it is possible to add 1 buzzer on the ERROR LED pin (3.3V Active Buzzer) and 1 small OLED module to be able to see the operating status, (connection status, error, flow rate, etc.) of the whole. system .

To connect ESPrtk with RTK receiver, Ethernet, OLED …, [**Click here for more detail. **](http://esprtk.wap.sh/tt/t3/connect_essprtk_to_other.html)
