PCB to order for FED3.2

[Thomas Huff]

Hi all,

My name is Thomas; I'm a PhD student in the Chu lab at Georgetown and have been using the FED3.2 to run operant experiments on some of our PD mouse models. It's been a really great tool! I'm writing because I'm now trying to build some more devices from scratch (partly to save a bit of money and partly as a fun project to learn more about electronics), and I had a question about which PCB I should order. 

From the hackaday page, I found a link to order this board at OSH Park: https://oshpark.com/shared_projects/1GtMZini However, I noticed that the file is dated 2018 and so I wasn't sure if it's been superseded by a newer version. I then found a few different PCB folders on the GitHub page here: https://github.com/KravitzLabDevices/FED3/tree/main/Electronics  But because I'm a novice at electronics and PCB boards, I wasn't quite sure if these were replacements for the hackaday version or perhaps supplements. 

So my question is: If I want to try building a couple of FED3.2 devices from scratch, can I order the PCB board from Hackaday/OSH Park listed above? Or do I need to order an updated PCB (with a new BRD file)?

Thanks in advance for any insights! (I do understand that I can order preassembled kits from openephys, but I thought it would be a good teaching exercise to assemble some from scratch. I have most of the other adafruit components already.)
