Company Details:

Inventek Systems is a USA-based, full-service wireless solutions provider focused on embedded 802.11 Wi-Fi, Bluetooth, GPS modules. Inventek supplies WICED compatible modules and also augments the WICED platform by adding an easy-to-use AT Command software called IWIN. This family of WICED compatible serial-to-WiFi modules is caller the eS-WiFi family.

AT Commands from a host microcomputer are sent to the eS-WiFi module through the UART, SPI or USB interface. Inventek's modules can be programmed with either WICED firmware or the IWIN AT Command firmware.

Our Cypress Serial to Wi-Fi development platform called ISMART (Inventek Systems Module Arduino Test) IoT platform is a user-friendly Arduino form factor, 3.3V shield . 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 Cypress PSOC4 and others. Sample projects are available in IWN Support (IWIN - MCU reference designs).


The ISMART shield supports the following Cypress radios that all are support our standard L44 & L54 compatible footprint:

  • ISMART43362-E : 2.4 GHz Wi-Fi 802.11 b/g/n based on Cypress CYW43362 Radio, STM32F205 micro
  • ISMART43340-C : 2.4 & 5 GHz & Bluetooth & BLE combo., 802.11 a/b/g/n based on Cypress CYW43340 Radio, STM32F405
  • New ISMART43903-E : 2.4 GHz 802.11 b/g/n based on Cypress CYW43903 SOC with Cortex R4
  • ISMART4343-C : 2.4 GHz 802.11 b/g/n & Bluetooth and BLE combo based Cypress CYW4343 combo Radio, STM32F412


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 Cypress PSOC 4 and other microcontrollers.

The following eS-WiFi modules for IOT applications that are footprint compatible support both the AT command as well as the Cypress WICED SDK.
