**Is your feature request related to a problem? Please describe.**
It would be nice if mqtt-io supports `XL9535` relay board.
**Describe the solution you'd like**
Normal integration like othe…

motor faders barely work at half the voltage/speed they are designed for.
if run with higher than 5v (should be 10 and testing at 12) they have a difficult time reaching the correct location and just…

Found a library for the TCA9554 io_expander, but is there also one for the PCA9554 expander? Using it on an Adafruit Qualia board with ESP32-S3 to connect a 40 pin LCD display. The SPI interface for t…

Just as a hypothetical - what would be the feasibility of emulating a real ISA bus on the PC Emulator? Ignore the hardware aspects for now (I'm thinking a bunch of SPI IO expanders like the MCP23S17),…
