Panasonic Industry PAN1781 Series Bluetooth® 5.0 Low Energy Module

The newest addition to the lineup based on the Nordic nRF52820

The Panasonic Industry PAN1781 Series Bluetooth Low Energy Module is the newest solution for IoT applications requiring long-range capabilities.

This newest addition featuring the Nordic nRF52820 Single-Chip Controller to the Panasonic Industry Wireless Connectivity RF Module product line is ideal for IoT Wireless Connectivity applications!

In addition, the ultra-low current consumption of the NEW PAN1781 Series makes the module an ideal choice for battery powered devices. With the Cortex® M4 processor, 32kB RAM, and the built-in 256 kB flash memory, the PAN1781 Series RF Module can easily be used in standalone mode to eliminate the need for an external processor, saving complexity, space and cost.

The Bluetooth 5 features as the LE coded PHY for an elongated range or the high speed 2M PHY are supplemented by the support of angle of arrival (AoA) and angle of departure (AoD) direction finding using Bluetooth.

An output power of up to 8dBm and the high sensitivity of the nRF52820 in combination with the LE coded PHY make the NEW PAN1781 Series RF Module very attractive in applications where a long range is required. The PAN1781 Series RF Module also supports Bluetooth Mesh, Thread and Zigbee Mesh Protocols. A 128-bit AES/ECB/CCM/AAR co-processor may be used for on-the-fly packet encryption.
