TractorPilot RTK Autosteer on Raspberry Pi 4 for £500

[kunzo]

Hi guys!
I've started building autosteer system based on Raspberry Pi 4 with components described here - https://tractorpilot.com/forum/topic/6/where-to-buy-hardware-modules
Will share my progress in this topic.
I like the idea that all the modules are connected directly to Raspberry Pi and I don't have to order manufacturing of special PCBs or buy Windows Tablets.

It will be good to hear it you get on. My first instal of agopengps was before they had the option of PCBs and wiring up all the components like the IMU and ADC is a lot nicer with a board to plug them into.

That "bright" LCD screen appears to be half to a quarter of the brightness of the toughbooks commonly used for agopengps. I would suggest looking for one at least 400 cd/m2

Isn't 750cd/m2 bright enough?

The tablet in the link you posted is only 220cd/m2. That'll be Chinese cd/m2, so in reality it could only be half that!

A used panasonic fz-g1 is only a few quid more, and can most definitely be seen in bright sunlight (not that there's been much of that yet this year!)

What software will you be running on the raspberry pi? Good easy to use software really is also essential....

750 should be good, but 220 was all I could see in the links.

Some people were trying to get agopengps running on a pi a few years ago. One of the issues was that a second hand toughbook was about the cheapest and readily available way to get a touch screen that was robust and bright enough.

The second screen is 750 cd/m2

Worked under Windows on an rpi5 for me, not bad performance either.
