Low Power WiFi Modules

Low power series wifi modules products are of low cost, low power and small size, which are suitable for data transmission of small data volume and low frequency.

The hardware of low power wifi modules integrate MAC, baseband chip, RF transceiver unit and power amplifier. And low power wifi modules support Wifi protocol and TCP/IP protocol.

Features:

  • Simultaneous AP Only or Client (STA) Only Modes
  • Industrial grade 802.11b/g/n Wi-Fi Module for low power Enterprise IoT
  • Integrated TCP/IP protocol stack
  • Supports security protocols WPA/WPA2
  • Supports Smart Link Function for both Android and iOS devices
  • Integrated low power 32-bit MCU
