    The ISM43340-M4G-L44-E is an embedded 2.4 and 5 GHz Wi-Fi 802.11 a/b/g/n, Bluetooth Low Energy (BLE) and Bluetooth 4.0 module. The module hardware consist of a Broadcom BCM43340 Quad Combo radio, antenna and a STM32F405 host processor with a standard USB, SPI or UART host interface capability. The Wi-Fi module requires no operating system and has an integrated TCP/IP stack that only requires a simple AT command set to establish connectivity for your wireless product. The module has a very small 14.70mm x 34.22mm surface mount footprint and has full FCC and CE module certification. This product is targeted for low cost embedded wireless applications and enables a quick, easy and cost effective method adding WiFi , Bluetooth, and BLE connectivity to your platforms.

    A summary of the key module features:
  • 802.11 b/g/n Compatible based on Broadcom MAC/Baseband/Radio device.
  • Fully contained TCP/IP stack thus minimizing host CPU requirements Configurable though AT commands ( In development).
  • Host interface: USB, UART, SPI up to 25+ MHz Network features ICMP ( Ping), ARP, DHCP,TCP, UDP BLE, Bluetooth
  • Over the Air updates
  • Secure WiFi authentication WEP-128, WPA-PSK (TKIP), WPA2-PSK

  • The -10C means that this is a newer PCB design that adds 10 extra internal pads. The module is still compatible with the L44 LGA but has 10 more internal pads that are connected to the STM32F405.
