Accessories

A complete range of accessories for your UAV needs.

MicroPilot offers a complete range of accessories for your autopilot needs. Whether you need exact compass headings, highly accurate altitude information, communication with your autopilot while in flight, or an analog-to-digital converter for additional sensors, MicroPilot has the product to fully customize your autopilot program.

ADC (Analog to Digital Converter)

The MicroPilot autopilot can support two external analog-to-digital converters (ADC). Using ADCs, you can display data from external sensors on the HORIZONmp ground control station.

  • Additional analog input channels provide enhanced data collection capabilities
  • Up to a total of 16 channels
  • 24-bit resolution
  • Input current: 100 pA, Chopper Stabilized
  • Instrumentation amplifier
  • Scalable input span (bipolar/unipolar): 25 mV, 55 mV, 100 mV, 1 V, 2.5 V, 5 V
  • Built-in noise filter
  • 5 Hz sample rate
  • 3.8 cm x 3.2 cm

COMPASS

The MicroPilot compass is a 3-D compass that compensates for pitch and roll. This accessory is useful when flying in high winds as it gives an accurate indication of where the nose of the plane is pointing, unlike the GPS heading which is the direction the plane is heading.
 
  • Provides heading information
  • Provides wind velocity and direction
  • Allows for greater tolerance of high winds
  • Provides dead reckoning capabilities
  • Provides heading information with no speed — used for hovering applications
  • 3-D aircraft capable — it provides accurate heading information even during banked flight, unlike the accelerometer-based 3-D compass
  • 2.6 cm x 3.2 cm

CAN Bus Autopilot I/O Expansion

MicroPilot’s CAN bus I/O expansion module extends the autopilot’s capabilities by providing remote connections for servo outputs and a remote compass over CAN bus. This allows I/O to be located where it is needed in the UAV, simplifying integration and reducing the amount of wiring routed back to the autopilot.
 
  • Conformal Coating / Underfill
  • Environmental Stress Screen
  • High reliability connectors
  • Remote Compass Support
  • 8 PWM Servo Out
  • 2 CAN boards per autopilot
  • IPC Class 3

RS232/RS485/TTL Converter

There is no shortage of inexpensive RS-232, RS-485, and TTL converters on the market. However, many are built to the lowest possible price point, using low-cost connectors and receiving little validation beyond basic functional testing. When a serial interface sits between mission-critical systems, reliability matters. MicroPilot’s isolated RS-232/TTL/RS-485 level shifter is engineered for demanding UAV applications, providing signal-level conversion, electrical isolation, and dependable communications in electrically noisy environments.
 
  • TTL, RS232, RS485
  • 4 Channels
  • Conformal coating/underfill
  • Environmental Stress Screen
  • High reliability connectors
  • RF Isolation
  • IPC Class 3

RPM Thermocouple Signal Conditioner

Thermocouple and RPM signals often originate in electrically noisy areas of a UAV, close to engines, ignition systems, motors, and wiring. MicroPilot’s isolated thermocouple and RPM signal conditioner conditions these signals while providing electrical isolation from the avionics system.

 
  • RPM Sensor Signal Conditioning
  • K-Type Thermocouple Signal Conditioning
  • 2 RPM Sensors and 3 Thermocouples
  • Conformal coating/underfill
  • Environmental Stress Screen
  • High reliability connectors
  • Optical Isolation
  • IPC Class 3

PPM Encoder

There is no shortage of inexpensive PWM-to-PPM encoders on the market. However, many are built to the lowest possible price point, using low-cost connectors and receiving little validation beyond basic functional testing. PPM is often a mission-critical autopilot input, so reliability matters. MicroPilot’s PPM encoder is designed and manufactured for demanding UAV applications.

  • 8 PWM in, 1 PPM out
  • Selectable 3.3V or 5V output
  • Automotive-grade components
  • Conformal coating/underfill
  • Environmental Stress Screen
  • High reliability, locking connectors
  • IPC Class 3, ESD protection
  • 7V to 30V supply voltage with reverse polarity protection
  • 35 by 25 mm, 25 grams with cables
  • -40C to +85C operating range
