ISMART 43903-E Arduino Shields – Wi-Fi 2.4 GHz

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. (more…)

ISM43903-R48-L54-E/U Serial-to-WiFi Module

The ISM43903-R48-L54-E/U is an embedded 2.4 GHz Wi-Fi module. The Wi-Fi module hardware consists of a Cypress 43903 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, SPI or UART interface capability.

The Wi-Fi module requires no operating system and has an integrated TCP/IP stack that only requires a simple AT command set to establish connectivity for your wireless product. The module has a very small 14.5mm x 30mm surface mount footprint and has full FCC and CE module certification. (more…)

What additional certifications do I need to have for my end product that uses your certified module?

Even though the eS-WiFi module is certified, the end product will still have to go through a small portion of RF certification. Also developers may need to apply for country specific certifications.

Maximum number of supported sockets?

A maximum of eight (5) TCP or UDP sockets are supported on the ISM43362 module and two (2) for the ISM4319 module.

Do you support SSL/TLS security?

We are developing SSL/TLS security capability for enabling HTTPS secure Webserver.

Do eS-WiFi modules support Wi-Fi Protected Setup (WPS)?

Yes, we support both methods of WPS (push button and PIN method).

What microcomputer is used on the eS-WiFi module?

STMicroelectronics Cortex M3, ST32F103 and ST32F205. The TCP/IP stack and WiFi firmware use one of these microcomputers.

How do I set up a TCP Client?

1. Set Protocol to TCP
2. Set Remote Host IP Address
3. Set Remote Port
4. Start TCP Client
EX.
P1=0      Select TCP Protocol
P3=192.168.1.2      Set Host IP Address
P4=8001      Set Port 8001
P6=1      Start TCP Client

Does the SoftAP mode work with Android and iPhone as clients?

Yes, Es-WiFi modules operate in Infrastructure mode so both iOS and Android devices can connect.
