The ISMART43903-E (Inventek Systems Module Arduino Test) IoT platform is a user-friendly Arduino form factor, 3.3V shield . The ISMART43903-E shield is assembled with the Inventek eS-WiFi ISM43903-R48-L54-E/U module.
The Wi-Fi module hardware consists of a Cypress CYW43903 SOC with ARM Cortex-R4 clocked at 160 MHz (in 1× mode) or up to 320 MHz (in 2× mode), an integrated antenna or optional external antenna, 1 MB of SRAM and 640 KB ROM available for the applications processor.
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 following Inventek eS-WiFi modules that all support our standard L44 & L54 compatible footprint:
New ISMART43903-E : 2.4 GHz 802.11 b/g/n based on Cypress CYW43903 SOC with Cortex R4
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.
