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.

Can we integrate our custom applications on the modules internal processor?

The internal processor of the modules is not accessible to the developer. However, Inventek offers the option of integrating your code with the on-board microcomputer’s firmware. Simply contact Inventek Systems for further details.
