Radio Module installation guide The Aurora miniRITE 312 T Rc 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 receiver modes with higher data rates and connected to a short wire antenna. Aurora miniRITE T 312 Rc Radio Model 3D overview Below the main flex PCB of the Aurora miniRITE 312 T Rc radio model with the most important electrical and electro-mechanical components can be seen:
Aurora miniRITE 312 T Rc Radio Model Main PCB Top side 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 telecoil is also used for wireless battery charging. The Aurora miniRITE 312 T Rc radio model requires only a single cell rechargeable 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 312 T Rc 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:
Aurora miniRITE 312 T Rc Radio Model Main PCB Bottom side 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 Aurora miniRITE 312 T Rc 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 312 T Rc radio model. The Aurora miniRITE 312 T Rc radio model is intended to be installed in Bernafon and affiliated wireless hearing aid devices of the miniRITE 312 T Rc (Receiver-
In-The-Ear) wearing style. Bernafon Radio Model - Regulatory Label Information for USA & Canada Radio Model Name: Aurora miniRITE 312 T Rc Contains:
