PAN1781 Bluetooth Module
2 Overview
The PAN1781 is a Bluetooth 5.1 Low Energy (LE) module based on the Nordic nRF52820
single chip controller.
The Bluetooth 5.1 features additionally a higher symbol rate of 2 Mbps using the high speed
LE 2M PHY or a significantly longer range using the LE coded PHY at 500 kb/s or 125 kb/s. The
new channel selection algorithm (CSA#2) improves the performance in high interference
environments. Furthermore, the new LE advertising extensions allow for much larger amounts
of data to be broadcasted in connectionless scenarios.
An output power of up to 8 dBm and the high sensitivity of the nRF52820 in combination with
the LE coded PHY make the module very attractive in applications, where a long range is
required.
In addition, the ultra-low current consumption of the PAN1781 makes the module an ideal
choice for battery powered devices.
With the Cortex-M4 processor, 32 kB RAM, and the built-in 256 kB flash memory, the PAN1781
can easily be used in standalone mode, thereby eliminating the need for an external processor,
saving complexity, space, and cost.
The PAN1781 also supports angle of arrival (AoA) and angle of departure (AoD) direction
finding using Bluetooth.
A 128-bit AES/ECB/CCM/AAR co-processor may be used for on-the-fly packet encryption.
