Modul
LORECA LOR2201BCR CloudLinkTM Hearing Aids Bluetooth System-in-Package
The module is specifically designed for hearing aid devices requiring
communication, high performance audio processing capabilities and programming
flexibility when form−factor and power consumption are key design constraints
The L O R 2 2 0 1 B C R SiP module is a hearing aid processing system,
based on RISC-VMCU, mixed−signal audio processing system, 32bit
Risc Core for link management.Compaction for hearing aid devices，
connection for audio source and communication.
