Transceiver Module S2LP Based 433MHz RC-S2LP-434

RC-S2LP-434 module is based on an STMicroelectronics S2-LP transceiver. This device is a high-performance ultra-low power RF transceiver designed for RF wireless applications in the sub 1GHz band. The module is designed for maximum performance in a minimal space, with four programmable I/O pins. Programmable from external microcontroller via SPI interface. Please refer to the S2-LP datasheet (www.st.com) for more information and details.

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 these 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.
  • For 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 ensures robust signaling for long-range communications.
  • Ready for use SMD mounting (15x 22mm)
  • Metal shield.
