RC-S2LP-XXX module is based on STMicroelectronics S2-LP transceiver.

This device is a high performance ultra low power RF transceiver designed for RF wireless application in the sub 1GHz band.
The module is designed for maximum performance in a minimal space, with 4 programmable I/O pins.

N.3 Versions available :
- RC-S2LP-434 Freq. : 433MHz
- RC-S2LP-868 Freq. : 868MHz
- RC-S2LP-915 Freq. : 915MHz

Sub-1Ghz technology is becoming one of the chief driving forces behind the Internet of Things (Iot), in particular this type of module is ideal for this applications basically for the following reasons :

  • Ultra low power consumption, the consumption of this device is 7mA when receiving and 20mA when transmitting at +14dBm (11mA at +10dBm) in sleep mode the consumption is 0.7µA.
  • Long range operations, the sensitivity parameter is -109dBm at data rates of 38.4 kbps and down to -128dBm when the data rate is 0.3kbps. Interference from other wireless communications can be overcome with 90dB of blocking. The RF output power levels can reach up to +16dBm. All this ensure a robust signaling for long range communications.
  • Ready for use SMD mounting (15x 22mm)
  • Metal shield.

EVALUATION BOARD -----> RC-S2LP-XXX-EW

The RC-S2LP-XXX-EW is an evaluation board based on the RC-S2LP-XXX module.

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)
- STSW-S2LP-SFX-DK (S2-LP SigFox Demo)

RC-S2LP-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.
