Microhard pMDDL 2350 ISM IP Radio - 2.4GHz

The operational range is highly dependent on antenna selection, terrain, and regulatory power limits. With its adjustable RF output up to 30 dBm (1W) and high receiver sensitivity, the module is designed for reliable beyond visual line of sight (BVLOS) links, typically achieving several kilometers to tens of kilometers in clear conditions when paired with high-gain directional antennas.

Integration is primarily via its serial (RS-232/RS-485) or Ethernet interfaces. For a Pixhawk, you would typically connect the radio's serial port to a TELEM port on the autopilot, configuring the baud rate in your ground control software (e.g., QGroundControl, Mission Planner). The Ethernet ports can be used for higher-bandwidth applications or to network multiple devices, requiring IP configuration within the radio's web interface.

The pMDDL 2350 utilizes robust error correction (ARQ) and selectable channel bandwidths to maintain link integrity. While its datasheet specifies operation on the 2.4 GHz ISM band, for detailed modulation schemes and interference mitigation techniques like FHSS or DSSS, you should consult the official Microhard product documentation or datasheet attached to the product listing.

The module accepts a wide input range of 5 to 15V DC, drawing between 5 to 15 watts of power depending on the configured transmit output level. At maximum RF power (30 dBm), expect current consumption near the upper end of this range. A stable, clean 12V source is commonly used in UAV applications, often connected through the vehicle's main power distribution board.
