New Bluetooth 5.3 Low Energy (LE) module from Panasonic with LE audio
Panasonic's PAN1783 is a Bluetooth 5.3 Low Energy (LE) module. At its core is the Nordic nRF5340 single-chip controller. The module is available with either an on-board chip antenna or an RF bottom pad. The module uses the functions of Bluetooth 5.3, including isochronous channels and LE audio, and supports a high throughput of 2 Mbps, advertising extensions and long-range communication. It integrates the extensive functions of the nRF52 series and improves performance and memory while maintaining low power consumption.
