PWM Output

The NarinFC-H7 supports up to 14 PWM outputs. All outputs except M13 and M14 support DShot. Outputs 1-8 support Bi-Directional DShot.

The 14 PWM outputs are in 4 groups:

• Outputs 1, 2, 3, and 4 in group1
• Outputs 5, 6, 7, and 8 in group2
• Outputs 9, 10, 11, and 12 in group3
• Outputs 13 and 14 in group4

All outputs within the same group must use the same output rate and protocol.

Analog Inputs

The NarinFC-H7 has 2 user-accessible analog inputs:

• ADC Pin4 → SPARE1_ADC1 (6.6V tolerant)
• ADC Pin18 → SPARE2_ADC1 (3.3V tolerant)

Additional internal ADC channels:

• ADC Pin16 → BATT_VOLTAGE_SENS
• ADC Pin17 → BATT_CURRENT_SENS
• ADC Pin14 → BATT2_VOLTAGE_SENS
• ADC Pin2 → BATT2_CURRENT_SENS
• ADC Pin6 → RSSI_IN
• ADC Pin8 → VDD_5V_SENS
• ADC Pin11 → SCALED_V3V3

Building Firmware

TIP

Most users will not need to build this firmware! It is pre-built and automatically installed by QGroundControl when appropriate hardware is connected.

To build PX4 for this target:

make narinfc_h7_default

Supported Platforms / Airframes

Any multicopter / airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos. The complete set of supported configurations can be seen in the Airframes Reference.
