Build Version 2 Steer Board
Brian Tischlers PCB v2.
For having the best experience you should make a PCB with all the necessary components for start. I truly understand that a lot of people never touched a soldering station and never did something with electronics. I can tell you it’s pretty simple and with good information here, in the PCB drawing and help from some other contributors you will also accomplish it.
Here are some Video’s how to create your own PCB.
Creating PCB v2 (Wilbert Talen)
To get your own PCB, download the gerber and go to jlcpcb.com You can upload the complete zipfile to the site. After that you can order it and it will be send out to anywhere in the world. Minimum pieces is 5, so you got some spares if you accidentally destroy one.
The zipfile also contains a BOM list (build of Material) that you can use at Digikey to order all the parts you need. You can also order it at different stores by using that list.
NEVER USE ALIEXPRESS MMA OR BNO DEVICES I can’t tell it too much but those are bad copies from the orginal board. It will only give you lots of problems and headache.
Ready for fertilize
For only doing fertilize or spray you’re good to go with a GNSS device and a Tablet. You can create fields with boundaries in the software, and create some Guidance lines. In this state you can use it as a Visual Guidance system for spraying or fertilize. Also want to drive autonomously? Keep reading!
WAS (Wheel Angle Sensor)
The software needs your location, but for autosteerring the software also needs to know at which angle your steerings wheel currently are. Here’s a list for a few Sensors that might be good for you.
