Sbo Hearing DA_AU5_MNR_R Aurora5 miniRITE T R Radio Model

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 are implemented on a single hardware platform.
Additionally, a full-featured RFID tag (IC5) operating at 865 MHz – 928 MHz with an 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 a 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 FM I – Near Field magnetic
Induction) 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.

Radio Model – Quick Installation Guide

Radio Model Name: DA_AU5_MNR_R

The most important part of the radio model is the Engine Module (IC1) mounted on the main flex PCB, which connects it to both the EEPROM memory and all

Model Name: DA_AU5_MNR_R

external connections: On the top side these are the microphones, the battery terminals and the push button and coil antenna for the 3.84 MHz radio (L2). The telecoil (L1) is also used for wireless battery charging.
The Aurora5 miniRITE T R radio model requires only a single cell battery and an external speaker (also incl. the wire antenna for the Bluetooth radio part) to be attached and plastic shells, defining the industrial design of a hearing aid end product and holding everything together, in order to be operational.

On the bottom side of the main PCB of the Aurora5 miniRITE T R radio model the connector for the speaker unit assembly (where the wire antenna for the Bluetooth radio is an integrated part), the programming connector, EEPROM memory can be seen:

The most important parts inside the Engine module are a Digital-Signal- Processor (DSP), a radio Front-End (FE) chip for the 3.84 MHz radio part and an RF chip for the Bluetooth radio part – all mounted on a small rigid PCB again mounted on the main flex PCB. The Aurora5 miniRITE T R radio model also includes all voltage regulators and buffered data programming inputs on board. The DSP is the main processor controlling the functionality of both radios in the Aurora5 miniRITE T R radio model.
The Aurora5 miniRITE T R radio model is intended to be installed in Oticon, Bernafon, Sonic, Philips and affiliated private labels wireless hearing aid devices of the miniRITE T R (Receiver-In-The-Ear) wearing style.

Radio Model – Regulatory Label Information for Japan

Description: Radio module with 2.4 GHz low power transceiver to be integrated into various hearing instruments and associated devices.

Regulatory label:

• This device is granted pursuant to the Japanese Radio Law and the Japanese Telecommunications Business Law under the grant ID n
• This device should not be modified (otherwise the granted designation number will become invalid)
• NB: The regulatory label is not shown on the radio module itself or any end products with it, since they are too small for the label to be readable without any optical aids or magnification. Below the radio module is shown, indicating a size of about 6.5x11x28 mm.
