nRF54L05 Ultra-Low-Power Beacon
Build a next-generation ultra-low-power BLE beacon with the nRF54L05 — combining the latest CRACEN security hardware with the nRF54L series' record-breaking sleep current for 5+ year coin-cell life.
Build a next-generation ultra-low-power BLE beacon with the nRF54L05 — combining the latest CRACEN security hardware with the nRF54L series' record-breaking sleep current for 5+ year coin-cell life.
Platform: nRF54L05
Entry-level nRF54L series SoC with ARM Cortex-M33 and RISC-V co-processor. Ultra-low-power BLE 5.4 with 512KB Flash — the most affordable chip in the nRF54L family.
Use Case: BLE Beacon
Bluetooth Low Energy beacon for indoor positioning, proximity marketing, and asset presence detection. Optimized for years of battery life on a coin cell.
Why This Combination
The nRF54L05 delivers the lowest sleep current in the nRF54L family while including hardware cryptographic acceleration — ideal for beacons that need tamper-proof configuration and decades-long battery projection.
