the S2-LP is a successor to ST’s SPIRIT1 (RC-SPIRIT1-XXX) and offers increased transmission range, greater selectivity, ultra-low power consumption and high configuration flexibility for internet of things (IoT) applications. FCC Certified.

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.
Programmable from external microcontroller via SPI interface.
For more information and details, please refer to the S2-LP datasheet (www.st.com).

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.
