The Panasonic PAN9520, available now from Rutronik, is a 2.4GHz 802.11b/g/n embedded Wi-Fi module based on Espressif's ESP32-S2. This highly integrated, low-power, single-core Wi-Fi microcontroller SoC includes a high-performance Xtensa 32-bit LX7 CPU. It is also created for security and cost efficiency while preserving high performance. The integrated chip antenna and QSPI memory make the device ideal for a broad range of stand-alone and host-controlled applications. It is one of the smallest devices on the market (24mm x 13mm x 3.1mm)and enables a wide range of peripherals via interfaces such as full-speed USB OTG, SPI, UART, and I²C, among others. The module is offered either as a 4MB Flash version with 2MBPSRAM or a 1MB Flash version without PSRAM.

The company combines a high-performance CPU, a baseband processor (BB), a high-sensitivity wireless radio, a ROM bootloader, and a medium access controller in the device. It also possesses an encryption unit, chip-internal SRAM as well as module-internal QSPI flash, and PSRAM (4MB flash version). The module guarantees a secure data connection thanks to BIP, CCMP, TKIP, WAPI, WEP, and an AES accelerator. The integrated quartz ensures connection performance over the complete service life and at a temperature range from -40C to 85C. Simultaneous support of Access Point and Station Mode provides easy setup of multiple Wi-Fi connections from the module to smart devices and home network routers.

The ESP-IDF allows software development for a wide range of applications employing many program examples.

Application areas include building, automation, medical technology, robotics, and smart city infrastructures.
