USR-WIFI232-A2 is a 2.4 GHz Wi-Fi-to-TTL-UART module for adding TCP/IP network connectivity to serial devices and MCU-based equipment.

Best for

  • Adding Wi-Fi connectivity to TTL serial devices
  • MCU-controlled low-data-rate equipment
  • Industrial and smart-device telemetry

Avoid if

  • A direct RS-232 electrical interface is required
  • Lower-power Wi-Fi operation is essential
  • An external antenna connection is required for this A2 version

Check before use

  • 3.3 V power supply capacity
  • TTL UART logic-level compatibility
  • Wi-Fi range in the installed enclosure
