The Aurora5 miniRITE T R radio model (DA_AU5_MNR_R)

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 R 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 – Ne ar Fi eld mag netic

Induc tio n) 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 5.0)

transceiver using GFSK/2FSK modulation with 1 Mbit/s, 2

Mbit/s data rate 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.

Below the main flex PCB of the Aurora5 miniRITE T R radio model with the most important electrical and electro-mechanical components can be seen:
