BG7XSS This is an open-source project from overseas. I saw it being sold on Xianyu for $188, and if you have the ability, you can try to replicate it.

BI4IKE BG7XSS I've confirmed it – it automatically calculates the password… all you need to do is enter the call sign… I was having trouble accessing the APRS server on my network and kept thinking I needed to enter a password. Once I got home and connected to the internet, I could see the call sign on the map…
BI4IKE The replica is almost complete; I just need to connect the last crucial component, the connector, to the radio.
BH6RIZ BI4IKE Hey guys, how do I print a blank expansion board? I can't seem to find anyone who sells them. Would you be willing to sell me one? My WeChat username is [WeChat username]
BG7XSS BH6RIZ Even Xianyu (an online marketplace) is starting to buy finished products; there's no need to make them ourselves anymore.
