Here we go.
I will try to be much more clear now.
Here you can see Cobra M5 MAIN PCB with GRIP and X-AXIS ( MAG RES sensor PCB ) connected :
What I would like to do is to scrap the MAIN PCB and replace it with PRO MICRO PCB clone.
That means - I want to connect MAG RES PCB to PRO MICRO and connect GRIP to PRO MICRO.
Here is picture of Cobra M5 MAIN PCB from bottom side where you can see pinout descriptions :
[ upper left corner is USB pinout ]
[ top row from middle to right side are three axis - Z, Y, X pinout ]
[ right side is GRIP pinout ]
MAG RES connection :
As I mentioned earlier MAG RES PCB ( ANALOG AXIS ) has following pinout on MAIN PCB - 3.3v, Gnd, Axis ( as standard pot ). These three pins will be connected to PRO MICRO as follows - POWER, GROUND, AXIS INTERNAL ADC ( any ). Correct me if I am wrong pls.
( Pls see the PRO MICRO layout in my previous post )
GRIP connection :
As can be seen on the bottom part of MAIN PCB the GRIP has following pinout - Gnd, 3.3v, Latch, Data, Clock, RZaxis.
Now I think I can see the issue with the GRIP. It has three-position mode switch. This could complicate the connection to the PRO MICRO I guess. That’s why also ( probably ) the pinout says the strange words like LATCH, DATA, CLOCK.
So if anyone has any clue how to connect that GRIP to PRO MICRO, or if at all, that would be great, thx.
