Too much man bun java jockey for me. So the USB to TTL Serial Cable page says:
“Note: Please be aware that while the I/O pins in this cable operate at 3.3V, the VCC pin is 5V. The VCC pin is NOT 3.3V like the I/O pins.”
Well… the ones I got measure measure 3.3V. What’s up with that? Is this off of the FT232’s onboard 3.3v LDO ?
A schematic would be nice…
