The Aurora5 miniRITE T radio model (MI_AU5_MNR_T) contains two radio
transceivers running at 3.84 MHz and 2.4 GHz and both implemented on a single
hardware platform.
Additionally, a full featured RFID tag (IC5) operating at 865 MHz – 928 MHz with
internal antenna has been glued onto the PCB. The RFID tag has no electrical
connections related to the Aurora5 miniRITE T radio module.
The radio model is implemented in an engine module mounted on the main
PCB with connection to the antennas, telecoil, the microphones, the speaker and the
battery terminals. The radio model can be seen in 3D overview to the left.
The 3.84 MHz radio is a low power, short range inductive radio transceiver
( N F M I – N e ar Fi el d m agn et i c Indu ct i on ) working at a single channel at
3.84 MHz using MSK modulation with 320 kbit/s data rate and connected to a
small coil antenna.
The 2.4 GHz radio is a Bluetooth Low Energy (BLE core 5.1) transceiver using
GFSK modulation with 1 Mbit/s, 2 Mbit/s data rates, also capable of proprietary
reception modes (xBLE) with higher data rates (2 Mbit/s, 4 Mbit/s) using
2FSK/4FSK modulation. The 2.4 GHz radio is connected to a short wire
antenna with a proprietary antenna connector.
