LoRaWAN Support

WSL309S-N5(L) : 470 – 510 MHzWSL309S-N5(H) : 868MHz for EUWSL309S-N5(H2) : 915 MHz for USWSL309S-N5(H3) : 923 MHz for Asia

AT Commands

Extended Temperature Range: -40°C to +85°C

Ultra-Low Power Consumption (1.5uA @ sleep mode)

The WSL309S-N5 transceivers SX127x feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.

LoRaTM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.

◆ RECOMMENDED REFLOW PROFILE

Standard conditions for reflow soldering: • a. Pre-heating Ramp (A) (Initial temperature: 150℃): 1~2.5℃/sec; • b. Soaking Time (T2) (150℃~180℃): 60sec~100sec; • c. Peak Temperature (G): 230~250℃; • d. Reflow Time (T3) (>220℃): 30~60 sec; • e. Ramp-up Rate (B): 0~2.5℃/ sec; • f. Ramp-down Rate (C): 1~3℃/ sec.

1. Power output routing width recommended more than 1mm.2. Recommended to reserve capacitors to suppress ripple and noise.3. RF output need routing with 50ohm impedance line.4. Reserve the Pi-Matching for Antenna performance tuning.5. Reserve the TVS for ESD protection. (Option)
