General Description:

WNB303R is an SMD type module with LCC package, with an ultra-compact profile of 18.0mm × 16.0.0mm × 2.35mm, which can be easily embedded into applications. It provides hardware interfaces such as ADC, GPIO, and UART interfaces, and can meet almost all the requirements for IoT applications, such as smart metering, bike sharing, smart parking, smart city, security and asset tracking, home appliances, agricultural and environmental monitoring, etc.

Designed with power saving technique, the WNB303R consumes an ultra-low current of Typ. 3.3uA in PSM (Power Saving Mode). The module fully complies with the RoHS directive of the European Union.

WNB303R provides protocol stacks (UDP/TCP, CoAP, NIDD, Http(s)…etc.) and also supports LWM2M/MQTT cloud platform as below, which provide great convenience for customers’ applications.

  •   OceanConnect
  •   Tianyi platform
  •   OneNET
  •   The other international cloud platforms which support MQTT/OMA LWM2M protocol (Please contact with LITE-ON for details)

1) Within operation temperature range, the module is 3GPP compliant.
2) Within extended temperature range, the module remains the ability to establish and maintain an SMS, data transmission, etc. There is no unrecoverable malfunction. There are also no side effects on radio spectrum and no harm to radio network. Only one or more parameters like Pout(Output power) might be reduced and exceed the specified tolerances. When the temperature returns to the normal operating temperature levels, the module will meet 3GPP specifications again
