- Gen-4 LoRa Performance, Sub-GHz Focused:
Powered by the same fourth-generation LoRa® IP core as the flagship LR2021, the LR2012 delivers best-in-class sub-GHz radio performance: receiving sensitivity down to -141.5 dBm (LoRa SF12 @ 125 kHz) and transmit output up to +22 dBm, maximizing link budget for deep-indoor and long-range deployments.
- Cost-Optimized for LPWAN at Scale:
By concentrating solely on sub-GHz operation, the LR2012 removes the 2.4 GHz and satellite RF chains you don't need — you pay only for the capabilities you use. Sharing the same Gen-4 IP and Unified Software Platform (USP) as the LR2021/LR2022, it lets design teams build sub-GHz and multi-band products on one architecture, simplifying supply chains and qualification.
- Best-in-Class Energy Efficiency:
Maintains Semtech's industry-leading low-power standards: 5.7 mA receiving current, 470 nA sleep current, and 105 mA @ +22 dBm transmit — ideal for battery-powered, long-lifecycle metering and sensing devices.
- Enhanced Channel Activity Detection (CAD):
Fast CAD employs an intelligent adaptive threshold and early termination mechanism, significantly reducing the power consumption and time required for idle channel detection.
- Ready-to-Go for Prototyping:
This integrated kit featuring the XIAO nRF54L15 combines real-time OLED feedback and plug-and-play Grove connectors for rapid sensor integration. Its hardware is also pin-compatible Arduino Uno, STM32 Nucleo, and Nordic DK platforms.
