The RC-SPIRIT2-433-EK board is based on RC-SPIRIT2-433 RadioControlli’s module. This module is based on STMicroelectronics chip (S2-LP) that is a sub-1 GHz ultra-low power low data-rate transceiver, suitable for ISM bands and Wireless M-Bus.

The Evaluation board can be used instead of those provided by the chip manufacter (www.st.com) denominated STEVAL-FKIXXXV2. With this board it is possible to use all the SW resources provided for the development activity, in particular :

- STSW-S2LP-DK ----> S2-LP-DK Application Notes

>The RC-SPIRIT2-433-EK evaluation boards are designed to work in the sub 1GHz band (433/868/915 versions).

Some features on the boards are (see the picture belowe) :
• RC-SPIRIT2-433 module (A)
• Two rows with Arduino compliant connectors (D1-4)
• UFL connector (B)
• A NUCLEO-L152RE or NUCLEO-L053R8 evaluation board (G)
• A jumper for RC-SPIRIT2-XXX current measurement (H)

RC-SPIRIT2-XXX signal test points are split across two rows which are Arduino compliant connectors: CN1, CN2 and CN3, CN4. The RC-S2LP-XXX shield is connected to the Nucleo motherboard via the Arduino compliant connectors.

Includes Antenna SMA (433 or 868MHz) and connection cable UFL/SMA.
