The goals.

Drotek products always make users feel satisfied because of its excellent quality.

The ESPrtk development team realizes one thing: both ESPrtk and Drotek are aiming for one goal, which is to create high quality products at low cost.

Drotek is known as one of the first brands to provide the RTK community with high-precision professional positioning solutions with RTK chips from Ublox.

ESPrtk has over 3 years of development, and is also the first brand in the world to use the ESP32 chip to replace the CPU on RTK product lines with equivalent quality.

This is a good time for us to look to Drotek.

Drotek + ESPrtk.

The ESPrtk team then contacted directly with Drotek’s marketing specialist and technology engineer to discuss the cooperation model.

We trusted each other and the negotiation process of ESPrtk and Drotek has ended successfully.

ESPrtk and Drotek officially shook hands and started working together.

The first draft of the Drotek + ESPrtk board was then completed after a month.

It was then revised several times to match ESPrtk version 3.5.x and ESPrtk 3.9.x.

It fully supports the peripherals that ESPrtk 3.9.8 supports: ZED-F9P, WIFI radio, Bluetooth Classic , Bluetooth BLE, Ethernet, LoRa radio, SD Card, IMU sensor, Magnetic sensor, 3G/4G Ublox SaRa, Neopixel LED, expansion pin for OLED display.

This design is suitable for fans of F9P and ESPrtk.

And Yes ! You can use ESPrtk firmware for ESP32 on this board or program it by yourself or both of them.

(By default, this board, when on sale, supports the registration of the ESPrtk firmware so you can immediately use it for all applications and all sensors/module as a Plug-and-Play device.
To be able to program it, you need to cancel use ESPrtk firmware temporarily so that the ESP32 chip can accept your code.
Of course, because your ESP32 has been registered ESPrtk firmware before from the Drotek factory, you can still go back to using the ESPrtk firmware for free and forever.).

Other board.

Drotek also produced a smaller RTK version, the Beacon RTK .

Everything F9P RTK / ESP32 (WiFI / Bluetooth) / DA233 Antenna / Battery / LED / SD Card /IMU/, .. is in a single design.

Now is March 2021 and we are manufacturing DEV PCB for the first prototype. It will be sent to the ESPrtk development team for performance evaluation. A beautiful and smaller circuit board will be redesigned for commercial purposes.

Okay, now April 2021.

This board assembled in France by Drotek It was the first prototype JUST for code testing, it had a green PCB, have some bugs and missing some components . (Of course, we know).😊

A nicer and better DEV board will be available as soon as we test it and ensure it works well.πŸ˜‰πŸ₯°

Okay, now Jun 2021.

We continued development and bug fixes for the 2nd prototype of the Drotek Dev board. In process by Drotek ! Not the final version yet but will be the best version. Well done ! πŸ‘πŸ‘πŸ‘

Okay, now is the end of July 2021.

We ended the test with the 2nd version board.There is still much things to do in the near future for new boards ! Thanks to the efforts of the Drotek development team. In particular we would like to thank Ronan GUERINEL and Damien Marragonis ! You guys did a really great jobs ! πŸ‘πŸ‘πŸ‘
