@jcai, yes you are correct regarding the connections that will work on Voxl2 and Voxl2 mini.
Please reach out to https://modalai.com/contact and we will create a custom order for you. You should add a link to this thread. I will work with our team to get the right hardware for you.
You will need
M0159 M0181 two specific coax cables between those teo boards (18cm length?). M0155 (assuming you already have M0161 with a coax, but is your M0161 connected to M0173 camera front end?You should also get a tool for removing coax connectors - check at the bottom of this guide: https://docs.modalai.com/micro-coax-user-guide/ . I dont think we sell the tool, but it looks like the tool is out of stock (Mouser) - you will need it to disconnect your M0161 from M0173.. i will check if we can provide it.
Regarding length, it looks like the longest cable we sell is 18cm : https://www.modalai.com/products/mcbl-00084?variant=48956821733680 , and this is what i am using for testing Hadron.
