SH2050 Description

D7A v1.2 bi-band communication & MEMS sensor shield with SMA antenna operating in the 863-870 MHz (EU) and 902-928 MHz (US) ISM bands for Nucleo32 and Arduino Nano boards based on MuRata IoT module (SX1276 + STM32L0). SH2050 feature a multimode protocol stack, including DASH7, DASH7 over LoRa and LoRaWAN. Datasheet

The shield features the following communication options :

  • bi-band 863-870 MHz (EU) and 902-928 MHz (US) ISM bands operation
  • DASH7 v1.2 reference protocol stack (FSK / MSK physical layer)
  • DASH7 v1.2 over LoRa physical layer
  • LoRaWAN protocol stack configured in Class C mode and provisioned with TTN keys.

The shield features the following list of MEMS sensors :

  • Battery Monitoring
  • Light Sensor (TEMT6000)
  • Magnetometer (LSM303AGR)
  • Accelerometer (LSM303AGR)
  • Humidity Sensor (HTS221)
  • Temperature Sensor (HTS221)
  • Pressure Sensor (LPS25HB)

Who should buy it?

You should buy it if:

  • You want to evaluate the DASH7 Alliance Protocol (D7A).
  • You want to evaluate LoRaWAN and/or compare it to DASH7.
  • You target Low Power Endpoint Applications.
  • You want to deploy a D7A network to connect your custom made objects to the DASH7Board
  • You want to prototype your sensor application using MBED and use D7A to communicate.
  • You look for a  small prototyping platform with an acceptable form factor for initial object testing
  • You expect to develop your own application without prior communication knowledge


The shields are fully programmed an configured with WizziLab’s D7A v1.2 stack (FSK / MSK / LoRa). A procedure to upgrade the code when new releases of the stack is available.

An application example including the shield driver in source are available on MBED to program your application on the Nucleo board (D7A_1X_demo).


General Statement about radio emission

The WizziKit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION OR EVALUATION PURPOSES ONLY and is not considered by WizziLab to be a finished end product fit for general consumer use. It generates, uses, and can radiate radio frequency energy. Operation of the equipment may cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may be required to correct this interference.

Any use of radio frequencies and/or power availability of the WizziKit and its development application(s) must comply with local laws governing radio spectrum allocation and power limits for this evaluation module. It is the user’s sole responsibility to only operate this kit in legally acceptable frequency space and within legally mandated power limitations. Any exceptions to this is strictly prohibited and unauthorized by WizziLab unless user has obtained appropriate experimental/development licenses from local regulatory authorities, which is responsibility of user including its acceptable authorization.
