Laird Connectivity is a leading provider of wireless connectivity solutions that offers an extensive portfolio of innovative wireless modules, System-on-modules (SOMs), antennas, and internet of things (IoT) devices. Their BL5340PA series is a comprehensive line of robust, power-amplified Bluetooth Low Energy (LE) modules that utilize the nRF5340 SoC from Nordic Semiconductor to provide the highest performance at the lowest power budget. The BL5340PA series incorporates Nordic’s nRF21540 PA/LNA for increased TX Power applications. Laird Connectivity’s BL5340PA series offers compelling solutions that deliver high-performance, low-power, and secure wireless connectivity for a broad range of applications, including next-generation Bluetooth LE Audio, industrial automation, smart home devices, and more.

Designed to provide next-generation Bluetooth audio streaming, BL5340PA modules offer Bluetooth 5.2 LE support including Isochronous Channels and LE Audio. Additionally, their integrated dual-core Arm® Cortex M33 microcontrollers enable low-power core operation that is dedicated to wireless connectivity while a second, higher-performance core targets the end application. This further enhances the product's multi-protocol capabilities, which include Bluetooth LE, 802.15.4 (Thread / Zigbee), and NFC. The BL5340PA is also equipped with an ARM CryptoCell312, which enables secure key storage, trusted execution, and root-of-trust security features.

The BL5340PA series provides access to all nRF5340 hardware features and capabilities, such as USB access, transmit power of up to +18.5 dBm, 3.0V to 3.6V supply considerations, and an industrial operating range of -40 to 105°C. Laird Connectivity simplifies your next multi-protocol wireless design with multiple regulatory certifications that reduce development risk and enable faster time-to-market.
