IRA-S230ST01 - Murata Electronics

IRA-S230ST01 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the IRA-S230ST01?
  Murata recommends a 4-layer PCB with a solid ground plane and a separate power plane for the antenna. The antenna should be placed at least 10mm away from other components and the PCB edge.
• How do I ensure the IRA-S230ST01 operates within the specified temperature range?
  The IRA-S230ST01 is rated for operation from -40°C to 85°C. Ensure good airflow around the module, and consider using a heat sink or thermal interface material if the module will be operating in a high-temperature environment.
• What is the recommended antenna design for optimal performance with the IRA-S230ST01?
  Murata recommends a monopole or dipole antenna with a 50Ω impedance. The antenna should be tuned to the operating frequency of the module (2.4GHz) and have a minimum gain of 2dBi.
• How do I configure the IRA-S230ST01 for low-power operation?
  The IRA-S230ST01 has a built-in power-saving feature that can be enabled by setting the PWR_MODE pin to LOW. This reduces the module's power consumption to approximately 1mA.
• What is the maximum transmission power of the IRA-S230ST01?
  The IRA-S230ST01 has a maximum transmission power of +20dBm (100mW). However, the actual transmission power may be limited by regulatory requirements and should be adjusted accordingly.
