- The breakout is not isolated: ESP32 ground, breakout ground, USB ground, and DE-9 pin 5 are electrically connected.
- The breakout is electrically DTE-style: `TX`, `RTS`, and `DTR` drive the DE-9, while `RX`, `CTS`, `DSR`, `DCD`, and `RI` receive from it.
- A straight-through male-to-male gender changer changes connector gender only. Use a straight-through cable for a DCE peer and an appropriate null-modem cable for another DTE peer.
- The current female Adafruit breakout was validated in a temporary DTE-to-DTE lab chain using a straight-through male-to-male gender changer, a null-modem cable, and a USB RS-232 adapter. The gender changer corrected only the physical connector while the null-modem cable crossed the signal directions. A male version of the Adafruit breakout is planned as the cleaner permanent connector arrangement.
GPIO8 and GPIO9 are not adjacent on the official J1 header. GPIO3 and GPIO46 lie between them and are boot-strapping pins, so follow the printed GPIO labels instead of counting header positions.
