Recommend FC and GPS/Compass combo for Chibios

I have done quite a lot of testing with the omnibusv6 (not nano), and below are most of the details for setting it up based on my earlier pull request. I haven’t got to help out with the board description yet, but I did write it up back then. It’s quite similar to the nano but with some differences.
It is nice with the JST pins for GPS/COMPASS (per previous comment as I always get the soldering wrong). I have tested with a benewake lidar and esp8266 (wemos) for connection to ground station (so the board runs with all these plus gps/compass).

Board Connections (per March 2019 on master)

GPS (enabling use of the 6 pin JST for GPS/COMPASS)
SERIAL3_PROTOCOL # USART6

COMPASS (scl/sda at the default 6 pin JST)

Telemetry
SERIAL2_PROTOCOL # USART4

Available UART (lidar, GSC etc)
SERIAL4_PROTOCOL # USART3

RC input to be soldered to LED PIN (compatible with RX serial protocols).

Servos S5-S6 are available for use

Current/Voltage monitoring:

  1. BLHeli32:
    BATT_MONITOR 9
    BATT_VOLT_PIN -1
    BATT_CURR_PIN -1

  2. ADC battery monitor:
    BATT_MONITOR 4 (Analog Voltage and Current)
    BATT_VOLT_PIN 12
    BATT_CURR_PIN 11
    BATT_VOLT_MULT 11.0
    BATT_AMP_PERVOLT 38.0

RSSI
Option 1: RSSI_TYPE 2 (RX RSSI Analog input from receivers (Frsky etc.))
RSSI_CHANNEL (set to the channel number output from the receiveer, for example 16)

Using usart3 to connect to GS
SERIAL4_PROTOCOL 2
SERIAL4_BAUDRATE 921600
Connect to wifi, select UDP and 921600 Baud and connect.

To enable logging, set LOG_BACKEND_TYPE to 4
