[CA, USA/Taipei, Taiwan]
Raytac Group, a worldwide leader in wireless modules, wireless solutions, and a Nordic-recommended third-party module manufacturer, is pleased to announce the official release of the AN54LQ-AT and AN54LV-AT series, our newest Bluetooth® Low Energy AT Command modules built upon Nordic Semiconductor’s nRF54L15 ultra-low-power wireless SoC.
Designed for engineers who want to integrate BLE quickly and easily, the AT Command series comes with pre-loaded peripheral (slave) role firmware, enabling straightforward UART communication with a host MCU through simple AT Commands.
Built on Nordic’s next-generation nRF54L15 SoC, the series delivers exceptional power efficiency, reducing power consumption by approximately 50% compared to previous-generation nRF52-based AT Command modules.
The nRF54L15 AT Command family is available in five variants to satisfy different RF and mechanical requirements.
AN54LQ Series

– PCB trace antenna: AN54LQ-PAT (Click here for full product details)
– u.FL connector for external antenna: AN54LQ-UAT (Click here for full product details)
AN54LV Series
– Ceramic chip antenna: AN54LV-AT (Click here for full product details)
– PCB trace antenna: AN54LV-PAT (Click here for full product details)
AT Command Development Kit
– AN54LQ Series: AN54LQ-AT-UART-S (Click here for full product details)
– AN54LV Series AN54LV-AT-UART-S (Click here for full product details)
The standard AN54LQ family measures only 9.5 × 13.7 × 1.8 mm, while the AN54LV family further reduces the footprint to just 6.4 × 8.4 × 1.5 mm, making it an excellent choice for wearable devices, portable products, industrial sensors, medical devices, and other space-constrained applications.
Engineers can integrate Bluetooth communication(peripheral role) into an existing MCU platform without implementing the Bluetooth LE protocol or maintaining a Bluetooth LE firmware stack.
Acting as a seamless bridge between the host MCU and Bluetooth devices, the AT Command module enables easy wireless communication without any complexity of firmware development.
