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.

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 T 312 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.
