THA012201 3DR - telemetry data set for ArduPilot

Description

3DR Radio is a set that allows bidirectional transmission of telemetry data between the RC model (with the APM controller: 2.5, 2.6, 2.8) and a PC. Light and small device in a set with antennas and connecting cables. The radio modules have a power of 100mW (+20 dBm) and transmit the signal to a distance of about 1.6 km.

properties

• Uses HopeRF HM-TRP radio modules (based on SiLabs Si1000 microcontroller)
• Antenna connectors: SMA
• Operating frequency: 433 MHz
• Output power: max. 100 mW (20 dBm), adjustable from 1-20 dBm
• Receiver sensitivity: up to -117 dBm
• Range about 1.6 km on the antennas of the set
• Data transfer rates: up to 250 kbps
• Interface: TTL UART (TXD lines, RXD lines)
• Serial transmission, transparent
• Can be configured using AT commands
• The base transceiver seen in the system as a virtual serial port
• Power and communication available via the microUSB connector
• Power supply for a 5V mobile transceiver
• Power consumption: 120 mA (transmission with power +20 dBm), 45 mA (reception)
• The modules can work with a bi-directional amplifier to improve the range
• Support for frequency hopping with frequency hopping (FHSS)
• Support for adaptive time multiplexing (TDM)
• Support for LBT (listening for channel occupancy before transmission starts) and AFA (selection of free frequency)
• The function of repairing incorrectly received code (possibility of improving up to 25% of errors)
• Adaptive flow control when using APM
• Open-source software
• LED indicator of the established connection
• Dimensions of the mobile / base transceiver (without antenna): 49 mm x 26 mm x 11 mm

Included

• Base transceiver
• Transceiver for mounting in the RC model
• A set of connecting cables
• Two antennas with SMA connector for 433 MHz band
