Conversation
Add hardware documentation for the VOLOLAND NarinFC-H7 flight controller including pinouts, serial port mapping, PWM output groups, and analog inputs. Fix version badge to v1.17 and clarify RC_IN is wired directly to FMU via RC_INPUT driver. Based on work by @vololand and @hamishwillee from PR #26542. Signed-off-by: Ramon Roche <mrpollo@gmail.com>

According to Claude, only outputs 1–4 (Timer5) support bidirectional - since _bidi_timer_index = 0 is hardcoded and limits bidirectional to the first timer. @mrpollo
EDIT. Note, after looking at Jake's new PR it further says that this is the true statemnt:
Outputs 1–12 support DShot. Outputs 1–7 and 9–12 support Bidirectional DShot (output + eRPM). Output 8
supports Bidirectional DShot output only (no eRPM capture — STM32H7 Timer4 CH4 has no per-channel apture DMA).

Note, even if this is true, it might be an accidental limitation. Until recently (#26263) you could only 4, but that limitation seems to have changed https://docs.px4.io/main/en/peripherals/dshot#hardware-support
