I bought a really nice keyboard called Plum 87EC-S which is similar to Noppoo and Royal Kludge offerings. It has adjustable capacitive key switches and it is fully programmable.
Since it was very hard to find the programming application and English user manual of the keyboard I’m putting them up here for others to use:
Thanks go to Steven Dong from EZ MANDARIN SHOPPERS on Aliexpress for finding the software behind the Chinese firewall 🙂
