ISMART Arduino Shields – Wi-Fi & Bluetooth & NFC

The ISMART (Inventek Systems Module Arduino Test) IoT platform is a user-friendly Arduino and ST Micro ST NUCLEO compliant shield suited for all of your wireless application needs.

The ISMART shield is an embedded wireless internet connectivity platform that operates in the 2.4 & 5.0 GHz spectrum.  The ISMART hardware includes the option for  an Inventek eS-WiFi module consisting of the Broadcom BCM43362 (2.4GHz), or BCM43341/0 Dual-Band (2.4GHz / 5GHz) 802.11 a/b/g/n MAC/Baseband/Radio with Integrated Bluetooth 4.0 and NFC. 

The ISMART shield interfaces with the ST Micro  NUCLEO boards and is compatible with the Arduino UNO R3 connector layout (without software support for Arduino). The Wi-Fi module requires no operating system and contains an integrated TCP/IP stack. The module hardware can be used with Inventek's AT Command set (IWIN) or with Broadcom's WICEDTM SDK. ISMART Hardware Users Manual
