Panasonic – PAN9420 Fully Embedded Stand-Alone Wi-Fi Module


Specifically Designed for Highly Integrated and Cost-Effective Applications

Panasonic’s New PAN9420 Series Fully Embedded Stand-Alone Wi-Fi Module, is a 2.4 GHz 802.11 b/g/n Embedded Wi-Fi Module with integrated stack and API that minimizes firmware development and includes a full security suite. The PAN9420 is specifically designed for highly integrated and cost-effective applications.

The Module includes a fully shielded case, integrated crystal oscillators and a chip antenna. The PAN9420 Series combines a high-performance CPU, high-sensitivity wireless radio, baseband processor, medium access controller, encryption unit, boot ROM with patching capability, internal SRAM and in-system programmable flash memory. The Modules’ integrated memory is available to the application for storing web content such as HTML pages or image data. Parallel support of access point and infrastructure mode allows easy setup of simultaneous Wi-Fi connections from the PAN9420 to smart devices and home network routers. The pre-programmed Wi-Fi SoC firmware enables client (STA), micro access point (μAP), and Ad-hoc mode (Wi-Fi Direct) applications. With the transparent mode, raw data can be sent from the UART to the air interface to smart devices, web servers or PC applications.

PAN9420 Evaluation Kit

PAN9420 Evaluation Kit

The New PAN9420 Evaluation Kit is available with one PAN9420 Mother Board (MB), one PAN9420-ETU daughter board (includes the PAN9420 FCC version module), and one USB-cable packaged in a large case.

The PAN9420-ETU daughter board is equipped on the PAN9420-MB, which has two USB to UART converters allowing the hardware access to the two UART module interfaces (command and binary interface). The PAN9420 FCC version module comes pre-loaded with a firmware for IoT applications and a Panasonic Web content example. With a few simple steps the kit is ready to use.
