PAN1781 – Panasonics Bluetooth® 5.1 Low Energy Module based on the nRF52820

The Panasonic PAN1781 is a Bluetooth® 5.1 Low Energy Module based on the Nordic nRF52820 Bluetooth Chip. It supports the Bluetooth 5.1 long range and higher symbol rate of the 2Mbps using the high-speed LE 2M PHY are supplemented by the support of angle of arrival (AoA) and angle of departure (AoD) direction finding using Bluetooth. With an ultra-low current consumption of only 4.9mA in TX and 4.7mA in RX mode, the PAN1781 is very suitable for battery powered devices. The PAN1781 can easily be used in standalone mode. In addition, the PAN1781 supports Bluetooth mesh, Thread an also Zigbee mesh protocols.
