eS-WiFi: embedded Serial Wi-Fi
• Inventek’s “modular” wireless product offering (Radio + MCU + Certified
Antenna). These modules consist of 802.11a/b/g/n/ac Wi-Fi radios and
combinations of these radios with BT/BLE.
• All eS-WiFi module options support the same foot print enabling customers to
migrate across the entire eS-WiFi portfolio without requiring any changes to the
customer’s original PCB design.
• eS-WiFi modules include antenna certifications for Chip, Etched, and u.fl
antennas.
IWIN: Inventek Systems Wireless Interoperability Network:
• Inventek’s proprietary AT Command SW.
o All associated collateral and documentation can be found at
▪ https://www.inventeksys.com/iwin/getting-started-guide/
• Requires a Host processor to communicate to the eS-WiFi module serially.

ISMART: Inventek Systems Module ARduino Test IoT Evaluation Board
• Arduino form factor/footprint, no Arduino driver support.
• No additional hardware is required other than a PC to use the ISMART
evaluation board.
• Please Note: The three-way switch on the ISMART evaluation board must be in
the position closest to the Wi-Fi module (Position 1, UART USB), and use a
USB cable to plug the ISMART evaluation board into your PC.

2 Introduction
The Inventek ISMART (Inventek Systems Module Arduino Test) IoT evaluation board
platform is a user-friendly Arduino form factor compliant evaluation board suited for all
of your wireless application needs. Please note that there is no Arduino software
provided for this IoT development board.
The ISMART IoT evaluation board enables customers to quickly launch IoT products
based on Inventek’s eS-WiFi (embedded Serial Wi-Fi), portfolio of 802.11a/b/g/n/ac Wi-
Fi radios and combinations of those radios with BT/BLE, a Host MCU and certified chip,
etched or u.fl antenna options.
The ISMART IoT evaluation board is also supported by Inventek’s IWIN (Inventek
Wireless Interoperability Network), firmware which provides customers a robust user
friendly AT command set to simplify and accelerate IoT design and development. IWIN
enables customers to quickly get a Wi-Fi connected application up and running.
The ISMART IoT evaluation board plugs directly onto any target Arduino compatible
MCU/CPU/Sensor Development Board offering. The ISMART IoT evaluation board also
supports complete HW & SW IoT platform projects for various MCU requirements.
Examples of the ISMART IoT MCU Reference Design Projects include Infineon’s
XMC4500 MCUs, ST Micro’s STM32F MCUs, Analog Devices’ Shark DSP and CUP360
MCUs, and Cypress PSoC MCUs. In addition, the ISMART IoT MCU Reference Design
Projects also support third party Cloud applications such as AWS. For more information
on complete ISMART IoT MCU Reference Design Projects, please visit:
➢ www.inventeksys.com
➢ AT Command Support
➢ IoT MCU Reference Designs
The ISMART IoT Evaluation Board User’s Manual provides a detailed hardware and
software requirements overview as well as all required board connections.

2.1 ORDERING INFORMATION
NOTE:
• All ISMART EVBs are configured for the UART interface option.
• For SPI support, please download the appropriate SPI FW update from Inventek’s
website, www.inventeksys.com
• Please reference your target eS-WiFi module of choice Data Sheet for additional
information.
2.2 ISMART IoT EVB Overview
NOTE:
• The L44/L54 foot print compatible option for Inventek’s eS-WiFi modules enables
customers to migrate across Inventek’s portfolio as needed without requiring any
changes to a customer’s original PCB layout, enabling maximum flexibility as future
connectivity design requirements change.
• The ISMART IoT EVB is a 3.3V board not a 5V board (5V input & generates 3.3V IO
• The ISMART Mini USB connects to the Dual Port FTDI (Backside of EVB)
• The ISMART UART Position Switch selects the required UART connection
o Please reference Section 4, The ISMART – Arduino Pin Out Map for all details.
