ISMART 43903 IoT EVALUATION BOARD

The ISMART43340-C (Inventek Systems Module Arduino Test) IoT platform is a user-friendly Arduino form factor, 3.3V shield . The ISMART43340-C shield is assembled with the Inventek eS-WiFi module ISM43340-M4G-L44-C
It is a Dual band Wi-Fi 2.4 & 5 GHz & Bluetooth classic & BLE combo SOC supporting 802.11 a/b/g/n based on Cypress CYW43340 Radio, ST Microcontroller STM32F405 with 1 Meg of Flash and Antenna.
The ISMART shield is an embedded wireless internet connectivity platform for IoT development. It can be used as a stand alone development board running Inventek IWIN: AT commands software or Cypress WICED SDK. The ISMART boards plug into a variety of microcontrollers shields, such as ST Micro, Cypress PSOC, Analog Devices, Intel and others. Sample projects are available in IWN Support (IWIN – MCU reference designs).
The ISMART shield supports the Inventek eS-WiFi modules that all support our standard L44 & L54 compatible footprint. We recommend all new designs use the L54 footprint.
The ISMART shield can interfaces with a variety of microcontrollers and we have sample projects on how to setup and use the IWN AT command software running on an external microcontroller :
ST Micro NUCLEO
Cypress PSOC 4
Analog Device
The shield is compatible with the Arduino UNO R3 3.3V connector layout (without software support for Arduino). The Wi-Fi module requires no operating system and contains an integrated TCP/IP stack running on the module core. The module hardware can be used with Inventek’s AT Command set (IWIN) or with Cypress WICEDTM SDK.
