TRU35 is a high-power, small-size, half-duplex digital radio model which is designed using advanced 32-bit cortex M4 microcontroller technology, wireless transceiver RF technology, and digital communica-tion technology. It uses highquality RF components, excellent EMC and EMI processing
All in one Integrated with transmitting and receiving functions.
Radio Relay
Increase the transmitting distance by receiving data and transmit-
Power Protection
Two-stage surge protection is used to protect the radio from damage when the input voltage or current exceeds the normal range or positive and negative stages are reversed.
Good Heat Dissipation
One-piece molded case makes it easy to perform good heat dissi-pation.
Thermal Protection
TRU35 can adjust the transmit power adaptively, automatically reduce the power when temperature is too high, and increase the power when the temperature decreases. Ensure radio equipment is always in a stable power range and will not be damaged by overheating.
IP67 Protection
Bluetooth Function Bluetooth can be used to configurate operating mode, protocol, frequency, power level as well as receiving data and transmitting out using radio.
Long Transmission Distance
Transmission distance can reach 14Km with high power level (Op-timal conditions)
