The Aurora miniRITE radio model contains two radio transceivers running at 3.84 MHz and 2.4 GHz and both implemented on a single hardware platform.
The radio model is implemented in an engine module mounted on the
main PCB with connections to the antennas, 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 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) transceiver
using GFSK modulation with 1 Mbit/s data rate also capable of
proprietary reception modes with higher data rates (2 Mbit/s, 4 Mbit/s)
and connected to a short wire antenna.

Below the main flex PCB of the Aurora miniRITE radio model with the most important electrical and electro-mechanical components can be seen:
The most important part of the radio model is the Engine Module mounted on the main flex PCB, which connects it to both the EEPROM memory and all external
connections: On the top side these are the microphones, the battery terminals and the push button.
The Aurora miniRITE 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 Aurora miniRITE 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 and coil antenna for the 3.84 MHz radio can be seen:
The most important parts inside the Engine module are a Digital-Signal-Processor (DSP as either a DSP_1b or a DSP_1c version differentiating on the available
amount of available internal memory capacity), 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 Aurora miniRITE 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 Aurora miniRITE radio model.
The Aurora miniRITE radio model is intended to be installed in Philips wireless hearing aid devices of the miniRITE (Receiver-In-The-Ear) wearing style.

Radio Model - Regulatory Label Information for Japan
Radio Model Name: Aurora miniRITE
Description: Radio module with 2.4 GHz low power transceiver to be integrated into Philips hearing instruments and
associated devices.
Regulatory label:
NB: The
This device is granted pursuant to the Japanese Radio Law (電波法) and the Japanese Telecommunications Business
Law (電気通信事業法) under the grant ID n° 認証番号: 202-LSE010
This device should not be modified (otherwise the granted designation number will become invalid)
本製品の改造は禁止されています。（適合証明番号などが無効となります。）
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 on mm paper,
indicating a size of about 6x10x27 mm.
