Overview - Wiznet WizFi320 User Manual

1. Overview

WizFi320 is a powerful, generic Wi-Fi+BT+BLE MCU module that targets a wide
variety of applications ranging from low-power sensor networks to the most
demanding tasks.
At the core of this module is the ESP32-DOWD-V3 chip. The chip embedded is
designed to be scalable and adaptive. There are two CPU cores that can be
individually controlled, and the CPU clock frequency is adjustable from 80 MHz to
240 MHz. The user may also power off the CPU and make use of the low-power co-
processor to constantly monitor the peripherals for changes or crossing of
thresholds.
The integration of Bluetooth, Bluetooth LE and Wi-Fi ensures that a wide range
of applications can be targeted and that the module is all-around: using Wi-Fi
allows a large physical range and direct connection to the Internet through a
Wi-Fi router, while using Bluetooth allows the user to conveniently connect to
the phone or broadcast low energy beacons for its detection. The sleep current
of the ESP32 chip is less than 5 µA, making it suitable for battery powered and
wearable electronics applications. The module supports a data rate of up to
150Mbps, and 20 dBm output power at the antenna to ensure the widest physical
range. As such the module does offer industry- leading specifications and the
best performance for electronic integration, range, power consumption, and
connectivity.
The operating system chosen for ESP32 is freeRTOS with LwIP; TLS 1.2 with
hardware acceleration is built in as well. Secure (encrypted) over the air (OTA)
upgrade is also supported, so that users can upgrade their products even after
their release, at minimum cost and effort.
