@nut Have you examples of setups requiring 2 canbus and motor controller? Or analog WAS?
As you Said v2.5 is an option for this case.
As discussed, for CAN only, Tony’s board is the one to use. It’s hided in the support folder under “Misc”
There was a lot of discussion while designing this board, the main point was to quickly release a board to correct some littles tings while keeping it almost compatible with the previous version and also to give the ability to upgrade to serial BNO and Teensy analog reading (without ADS1115) which is under testing this summer.
Not for motor controller, but for hydraulics, yes. I use a CAN valve in the steering setup so one CAN is always needed for the steering bus (this is normal left/right valve, not autosteer ready type), second CAN channel goes to tractor bus for reading armrest buttons, communicating with hydraulics etc. If there’s an existing WAS on the tractor, then that is hooked up to the analog WAS channel.
We did all those things using the previous Standard board. So the micro should also be capable.
And here’s the code for Teensy:
Wiring was done in a way that we use the PIN that is directly wired to Teensy to trigger a relay board which in turn lifts the implement. That relay can override the switch that you use to lower / raise the implement. So you go to the field, lower the implement start driving then enable the “work switch” button on AgOpenGPS and at the end of the pass it does U-Turn and lift the implement.
(But if you ever decide to lift the implement middle of the field, etc. It could never lower it.)
jlcpcb is still missing some parts for this new pcb. Ampseals are easy to find elsewhere.
I found alternative header for teensy (JLCPCB Part #
C2883741) from Digikey, is it suitable?
It seems correct imo
They could read the silk on the pcb! .
The default position is correct with the regs from the list.
Where the defaults from the BOM (Mornsun) available?
Yes, any 2.54mm, 8.5mm height, header will work. I typicaly buy 40 pins headers and cut to lenght
Most 5v linear reg would work, just check the pin order and orientation.
JLCPCB probably have many alternates but they are not in the list because the oriention was not verified.
What size are those ethernet holes in teensy. I have 2.54mm male heads. Between holes there is 2mm in teensy. I could cut my 2.54 heads but it seems that they are too big for CN2
They also have to be extra long to reach the female headers. The 2mm headers should just barely stick out past the 2.54mm headers. I think 13 or 15 mm overal length but I would have to check.
If the lower socket is installed, then remove pin from strip and softly push true hole in teensy until they level with board. Then solder them.
I never use other pins. Works great for me.
