Which PCB for Nano + IBT-2 + BNO080 + simpleRTK2B Setup?

Hardware PCB

Hello everyone!

I’m putting together an AgOpenGPS autosteer system and have already purchased the following components from various sources:

  1. simpleRTK2B – Basic Starter Kit + antenna
  • From: ArduSimple
  • Price: R$ 1,552.50
  1. 9DOF IMU (BNO080/BNO085)
  • From: AliExpress
  • Price: R$ 123.56
  1. Euro Caminhões 12V windshield wiper motor
  • From: Mercado Livre
  • Price: R$ 231.03
  1. IBT-2 (BTS7960) 43A H-Bridge motor driver
  • From: Mercado Livre
  • Price: R$ 49.26
  1. Arduino Nano V3 (ATmega328 + CH340)
  • From: Mercado Livre
  • Price: R$ 35.90

Now I’m looking for guidance on which AgOpenGPS PCB design is best suited for these exact components (especially the Arduino Nano + IBT-2 driver + BNO080 IMU). Could anyone recommend the correct PCB revision, share Gerber files, or point me to the right forum thread? I’m hoping for something straightforward to assemble that supports the IBT-2 and includes headers for the BNO080’s I²C lines.

Thanks a lot for any help!

Have a look to :
Boards/Misc/PCB at main · AgOpenGPS-Official/Boards · GitHub

These boards are older boards for arduino but match not exactly for your needs ( IBT-2).

Would recommend you go for an All-In-One instead of PCBv2.

Thank you very much for the response, but why exactly does it not meet the needs of the IBT-2?

Thank you very much for the response. Why do you recommend the All-in-One? Is it easier, more convenient? I was looking into it, and the price difference isn’t that big. When I was more confused, especially in the beginning, I saw that the PCB was a big obstacle, but now I more or less understand how it works.

And the difference in hardware between the Nano, IBT-2, Teensy 4.1, and Citron is around R$500 or R$300. That’s not a huge difference for me, you know? I can choose, but my fear is making mistakes along the process. The Nano and IBT-2 are cheaper, but I believe that this current All-in-One model is easier because it is already more refined.

They should work fine with an ibt.

It’s just not the mainstream built.

All-in-one is recommended because it’s widely used and has by far the most support from the community.

I went to order the PCB All In One, and what happened? Some components are missing, as you can see in the screenshot. But I checked the list of alternatives, and there are none. So now what? What should I do?

I guess, mounting holes are designed for cytron, but pcbv2 works also fine with ibt2. You can connect your bno with jumper wires to pcbv2 as I did.
