I agree with the soldering problem, but @ScottJFrisby if you use solderpaste it is easier to transfer heat to the solder ring on the teensy and solder float better.
On the micro you find a 7803 voltage regulator to feed the F9P micro. Beside that regulator it has 3 v 3 printed, try to test voltage there.
Thanks, I will get some solderpaste and give it another shot on the connections.
Rosin core solder works really good
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?
These are the regulators I think. Micro use some 5v and 3v, Std all 5v.
Be careful with theses, sometimes JLCPCB put them backward.
These are Trough hole components, you can easily buy them at mouser/digikey and solder them yourself.
This is because the default Mornsun regs have been âcancelledâ due to Russian sanctions. JLCPCB must have erased their number.
The BOM should be updated
For anyone this helps, the 6 pin header for Ethernet is Samtec MTMM-103-09-G-D-280
Digikey and others sell it and this is the part that PJRC sells via their own website. 100% correct heights when used with a v4.5 that has the female socket on the board.
It turned out I had ordered a 5v regulator in U3 instead of a 3.3v when I selected a missing part.
However I have another problem. I followed this wiring diagram
but something isnât working. When I connect the 24 volt step up to the power It seems to decay the power feed to the board - I will get 5 volt but it rapidly declines to 0 volt within a few seconds. Any thoughts on what I am doing work?
Also, the jumper wire on the Cryton to the board for the 24 volt, is that on the ground or on the positive?
Thanks
Are you connecting pin 18 to cytron in power? Have you put the jumper wire on the board aswell which is dedicated for this purpose, pretty sure its marked on the pcb itself âpin 18 cytron inâ or something similar
I am working on finalizing my v4.5 board and have a couple questions:
If I am using the lock pin to control a relay for disconnecting the steer motor so I donât have to modify the cytron, do I need a NO or NC relay? Or do I still need to mod the cytron?
Do I just connect the ground from the cytron to any of the ground pins in the Ampseal? Or should I run a wire out of the enclosure?
No need to modify cytron. Yo need NO contact. Lock pin will output 12v when steering is active.
Ground is connected through pcb, you juat feed positive voltage on ampseal pin 18 for cytron.
⌠May be a sign of a short on the regulator side? Check all voltages.
⌠Jumper wire is +24V (positive) and must connect to PWR (positive).
Your pcb screenshot posted recently:
⌠There are a lot of bad solder joint on your teensyâs header soldering!
⌠around PWR terminal, looks like there is a bit smoke sign ? Is the trace on the bottom side ok?
Iâm just starting work on my board, soldered headers on my teensy and then moved to the little Ethernet pins. Before I soldered them on I noticed that the female headers on the Aio board are shorter and my pins on the teensy wonât reach. What does everyone do about that?
This is how I do it. Solder the female to the teensy and bridge the gap with the male. Think you could also pull pins out of regular headers and they would fit but it wouldnât be as clean.
Also, can a momentary button be used for the work switch? Or does it have to be a switch?
One last question, what about the mcp? Converter that there are gerber files for? Is that required with the ads on the board?
Thanks, had been thinking of stacking another female header on the Aio board, but I havenât got any 2mm headers yet to try it.
Has anybody been able to solve this problem?
Iâve been wanting to order PCB for more than a month now and header 3 pin is still unavailable.
Also, does anyone have spare AIO v4.5 standard board he doesnât need?
If all you are missing is a header you can buy it somewhere else and easily solder it on. You can cut down a longer one if you need to.
Hello, I have a question about using the Standard AIO for my Danfoss John Deere valve.
1- I need to put a jumper on the PCB for US.
2- Connect it with a 12V cable from the Cytron
Is this correct? The jumpers on the standard AIO donât match the AIO mini version.
Thereâs no documentation for the standard AIO jumpers.
