Īfter this I could convert the battery pack schematic to a PCB, albeit with its own set of problems Then I had to change the 'battery pack' sheet type to 'normal', and then I had to delete the 'main' page. Then I had to copy the 'battery pack' and 'PB1000' sub and sub-sub pages over to the sub-pages in the new schematic. OK, I was able to get the battery pack sub-page copied over to a new schematic file, but it was a major PITA! First I had to create two sub-pages in the new, blank schematic, with the 'hierarchy' flag set. I have attached the schematic if anyone wants to take a look Unfortunately, when I do a Ctrl-A to copy the schematic, then open a new schematic file and do a Ctrl-V, I get an error message because this sub-page references another page as a sub-sub block - argh!! So, I thought that I would copy the sub-page to a new schematic and do it as a stand-alone. Now I want to create a PCB of just one of the sub-pages (the battery pack), NOT the whole thing how do I go about this? If I simply select 'Convert to PCB', I get a bunch of garbage which makes no sense. All the sub-pages have the 'heirarchy' sheet type selected.
I created a hierarchical schematic with a main page, and then several sub-pages. The input numbers will also not match up to the inputs on the IO Pi.I have the same problem. The ground pin will need to be connected separately to the GND pin on the IO Pi board as earlier models did not include the ground on the IDC header. Note: The input board can be used with older versions of the IO Pi Plus and IO Pi Zero as well as the original IO Pi but you will need to only connect the 16 input pins on the IDC connector. The design files and Gerber files for the input board are available to download from our GitHub repository. The schematic and PCB files are included in Diptrace format, you can download a free version of Diptrace from The “Gerber Files.zip” file contains a zip of the Gerber files that can be uploaded directly to the PCB manufacturer of your choice. Gerber files are included in the GitHub repository and use a file name format compatible with several PCB manufacturers including iTead and Elecrow. For example, a 560R resistor will give a usable input voltage range of 3V to 12V. Our LED resistor calculator can be used to find the required resistance. The emitter for the FOD817C300 opto-isolator requires a maximum current of 20mA at 1.2V. The input resistors R1 to R16 will need to be specified for the input voltage. The input numbers match the pin numbering on the IO Pi Plus bus making it easy to read the inputs using our IO Pi software libraries. The 20 pin IDC connector uses the same pin configuration as the IO Pi Plus 2.1 so you can connect the two together using two 20 pin IDC connectors and a ribbon cable.
The 16 channel opto-isolated input board is suitable for use with the IO Pi Plus version 2.1 or later and the IO Pi Zero. To go with the relay board, we are releasing the design files for an opto-isolated input board. We made the design and Gerber files public so that anyone can make their own or modify the design to fit their needs. In 2017 we released the design files for a relay board to work with our IO Pi Plus interface board. For use with the IO Pi Plus and IO Pi Zero Created: | Last Updated:
