The S2SPI-HA/UA/NA-A-434 module is based on the ultra‑low‑power S2‑LP RF transceiver and operates in the 430‑470 MHz and 860‑940 MHz ISM/SRD bands. It offers multiple antenna configurations (UFL, helical, or no antenna) and includes a 4‑wire SPI interface, programmable RF output power up to +16 dBm, and low‑power consumption modes.
The datasheet details the mechanical drawing, terminal pinout, recommended PCB layout, and full electrical specifications such as operating voltage (1.8‑3.6 V), temperature range (‑40 °C to +85 °C), current consumption for various modes, TX power, RX sensitivity (‑131 dBm) and storage limits. Contact information for further support is also provided.
