Board Connections

GPS is attached to UART6

Telem is available at UART 1

The shared UART3/I2C pins are enabled only for I2C operation to allow external compass or digital airspeed sensor attachment.If at least one device attached externally, does not have pull-up resistors, then 2K ohm pull-up resistors will need to be added externally.

Configuration

Enable Battery monitor with these settings :

BATT_MONITOR=4

Then reboot.

BATT_VOLT_PIN 13

BATT_AMP_OFFSET 0.008

BATT_CURR_PIN 12

BATT_VOLT_MULT 10.925

BATT_AMP_PERVLT 58.0 (note, this value is valid if using Matek Systems FCHUB A5 current sensor)…will need to be calibrated to match actual current if using any other make of PDB board)

Dshot capability

All motor/servo outputs are Dshot and PWM capable. However, mixing Dshot and normal PWM operation for outputs is restricted into groups, ie. enabling Dshot for an output in a group requires that ALL outputs in that group be configured and used as Dshot, rather than PWM outputs. The output groups that must be the same (PWM rate or Dshot, when configured as a normal servo/motor output) are: 1/2, and 3/4.
