How to add RTK to Pixhawk UAS

Michael sent this project in to us! Michael says “Hello Adafruit! We here at Sky Horse Tech love the products
and service that Adafruit provides. One example is our recent DIY UAS RTK
module where we show everyone how to build a ZED-F9P unit with Adafruit
feather logger and OLED display for use on a Pixhawk GPS system. We have an
embedded video along with wiring diagrams and links to our Github OLED
sketch for the adalogger. We also have prior posts on similar ZED-F9P
projects using Adafruit components.”


In this project we explore how to add RTK functionality to your UAS (drone), specifically a UAS using Pixhawk. In previous posts and videos we built a ZED-F9P base and rover for ground-based RTK projects, we will use the same F9P GNSS module here. Since we are adding this to a UAS we will need to miniaturize the footprint so we have the lowest possible weight onboard.

For the plastic outer shell we are using a standard project case and have made the necessary cutouts using a rotary cutting tool (Dremel) and drilled for holes. In the pictures below, we provide the measurements and placement of those cutouts. We also have a complete materials list at the bottom of this post for all of the components used overall.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
