(1) HiWonder seems to have a 2020 cheaper model LX-20S. Did you see this when you ordered yours last time? This model has only one axis, but I think it is more affordable to fry, or for a project with many servos.
The TXS0102 module is from a TaoBao shop. I remember that they delayed my small order of 20 pieces, because they need to make large quantities for Singapore. Singapore has a reputation of making high quality products (sometimes military grade). So I think they require good quality TXS0102 too. Before that I tried different cheap versions of TXS0102/04/06/08 but found them problematic. So this time I am wiring a new one on bread board to do a more rigorous test.
I am thinking of testing LX-224 UART commands this weekend. I think I don't need to use Rpi python. A lazy way is to use Win10 RealTerm terminal emulator to send and receive commands to LX-224. I hjave been searching for an updated version of LeWanSoul command list. But I could not find one. This might be bad news, becasue they might have abandoned the project during LX-16.
