Key Features
- SX1268 Next-Gen LoRa: Successor to the SX1276 with superior sensitivity (-148 dBm), higher TX power (+22 dBm), and significantly lower sleep current (~1.6 uA) - ideal for battery-powered deployments.
- Ultra-Long Range: Achieve 10+ km line-of-sight communication at 433 MHz, penetrating obstacles better than higher-frequency alternatives.
- Ultra-Low Power Sleep: 1.6 uA deep-sleep current enables multi-year operation on coin-cell or small lithium batteries for remote sensor nodes.
- Compact 16 x 16 mm Footprint: Castellated half-hole SMD pads allow direct PCB soldering or use with breakout adapters for prototyping.
- Standard SPI Interface: Simple 7-wire SPI connection (MOSI, MISO, SCK, NSS, RESET, BUSY, DIO1) works with virtually any 3.3 V microcontroller.
- Wide Voltage Range: Operates from 1.8 V to 3.7 V, directly compatible with single-cell LiPo batteries without a regulator.
- Industrial Temperature Range: Rated -40 degreesC to +85 degreesC for outdoor and harsh-environment installations.
- IPEX Antenna Connector: Easily attach external 433 MHz antennas (spring, whip, or Yagi) for optimal range tuning.
Why Choose the Ra-01S over the Ra-01?
- Better Sensitivity: -148 dBm vs -137 dBm - approximately 10 dB improvement translates to significantly longer range or more reliable links.
- Higher TX Power: +22 dBm vs +20 dBm - more output power for challenging RF environments.
- Lower Sleep Current: 1.6 uA vs 1.5 uA (comparable, but overall power profile is improved with faster wake-up and more efficient TX/RX cycles).
- Modern SX1268 API: Cleaner register interface with BUSY pin for reliable command handling - eliminates timing guesswork common with SX1276.
- Drop-in Upgrade: Same 16 x 16 mm form factor and pin-compatible layout makes PCB migration straightforward.
