Looks like "Loongson 3A5000" (4 cores) is the only CPU reasonably available. There is a "3C5000" with 16 cores also but have been unable to find one. Both use a "7A2000" motherboard. There are multiple different listings floating around but this seems like the standard configuration: https://www.aliexpress.us/item/3256804566786115.html
