AIROC™ CYW20835 Bluetooth® LE System on Chip

The AIROCTM CYW20835 Bluetooth® LE So Cis a Bluetooth® 5.2 core spec compliant device for IoT applications. Manufactured using the industry`s advanced 40 nm CMOS low-power process, the CYW20835 employs high levels of integration to minimize external components, reducing the device footprint and costs associated with implementing Bluetooth® Low Energy solutions.

The AIROCTM CYW20835 Bluetooth® LE SoC is designed to support the entire spectrum of Bluetooth® Low Energy use cases for home automation, accessory, sensors (medical, home, security, and industrial), lighting, Bluetooth® Mesh, wireless input devices including game controllers, remote controls, keyboards, and joysticks or any Bluetooth® LE connected IoT application.
The CYBLE-343072-02 is the BLE module based on the CYW20835.
For both the IC and the module, there are Eval Kits availble:
The CYW920835M2EVB-01 contains a base board and a Bluetooth radio card which is mounted onto the base board and is the Kit for the chip CYW20835.
The CYBLE-343072-EVAL-M2B contains an Arduino Evaluation Board with the on-board AIROCTM module CYBLE-343072-02, one USB cable for USB - UART programming and convenient user buttons.
