Hello,
I'm a bit confused about all the versions and revisions. I want to build the latest DRV8225 Full + IR version on stripboard. I guess the file "myFocuser_hw203_DRV8825_Full_Layout.png" is the corresponding layout. Is this correct and ist this myFocuser2? And which is the corresponding excel-parts-list? Is it in file "myFocuserPro Parts List.xls" sheet DRV8825, or is this sheet corresponding to hw103 instead of 203?
Many thanks in advance
Best regards
Thomas

Hi Thomas
First, the below info is for MYFOCUSERPRO2 which is NOT moonlite compatible.
The same stripboard layout is used for MyFocuserPro (moonlite compatible, less features) or MyFocuserPro2 (not moonlite compatible and more features).
If you load the myFocuserPro firmware, you use the myFocuserPro apps and ASCOM driver or the Moonlight driver.
If you load the myFocuserPro2 firmware, you use the myFocuserPro2 apps, myFocuserPro2 ASCOM drivers - and thus cannot use Moonlight drivers or work with INDi
Tank you very much. What about the 10 kOhm resistor from D9 to IRSIG? It is in the Layout, but not in the schematic and also not in the parts list. And the 1 MOhm resistor is missing in the parts list.

Hi Thomas
As noted in the pdf manual, the stripboards reflect the original prototypes, whereas the PCB versions reflect the many changes and improvements made since the years havepassed. Thus yes, you will find that some things do not quite match up in a project of this size and scope with so many variations.
In terms the 10k this from memory was due to the prototype not using the little daughter board that comes with the IR module which has some 10K resistors and leds on it. So you do not need it and I have updated the layout. And its not needed in the parts list,
The firmware decides this - it is set to green led by default if everything is connected correctly, pb1 corresponds to move inm and pb2 corresponds to move out
Of course, if you then enable reverse direction it gets inverted

For the DRV8825 with IR, the stripboard layout is
https://sourceforge.net/projects/arduinoascomfocuserpro2diy/files/DRIVER%20BOARDS/BOARD%20DRV8825_HW203/DRV8825_HW203_IR/
For the parts list
https://sourceforge.net/projects/arduinoascomfocuserpro2diy/files/PARTS%20LISTS/myFocuser_DRV8825HW203_F_Parts.xls/download
Open the EXCEL file, on the bottom click the tab IR OPTION for additional IR Components
You also need the components on the DRV8825HW203F tab
ASSUMING MYFOCUSERPRO2
The firmware will be (enable the IR option when programming the controller)
https://sourceforge.net/projects/arduinoascomfocuserpro2diy/files/CODE%20ARDUINO%20FIRMWARE/Arduino%20Firmware%20myFocuserPro2%20v280.zip/download
and extract to get the Focuserv280_DRV8825_HW203 folder for the firmware (and be sure to copy the library folders as directed before attempting to program the controller).
The ASCOM Driver is
https://sourceforge.net/projects/arduinoascomfocuserpro2diy/files/CODE%20ASCOM/myFocuser2ASCOMSetup266.exe/download
The Windows application is
https://sourceforge.net/projects/arduinoascomfocuserpro2diy/files/CODE%20WINDOWS/myFocuserPro2_2_4_3_0.zip/download
and the manual for instructions.

and if you need ideas on how to mount the stepper motor

Copy the libraries as instructed
Enable the IR option when compiling the firmware

The 1M I find is in the parts list, if you can let me know the file are you referring to I can have a look but the file here looks fine.

Sorry, you're right the 1M is in the list.
I've another question: Which LED (green / blue) is assigned to which push button (1 / 2)?
The firmware decides this - it is set to green led by default if everything is connected correctly, pb1 corresponds to move inm and pb2 corresponds to move out
Of course, if you then enable reverse direction it gets inverted
