WiFi Development Tools (802.11) PIC-IOT WG Development Board

Description of product


Microchip Technology PIC-IoT WG Development Board (AC164164) is a perfect starting point for for engineers creating almost any IoT (Internet of Things) device, ranging from wireless sensor notes to intelligent lighting systems. This plug-and-play solution combines a powerful PIC Microcontroller (MCU), a CryptoAuthentication™ Secure Element IC, and a fully-certified Wi-Fi® Module to provide a simple and effective way to connect embedded applications to the Google Cloud IoT Platform.

Google Cloud IoT Core provides a fully managed service that enables designers to easily and securely connect, manage, and ingest data from devices at a global scale. The platform collects, processes, and analyzes data in real time to enable designers to improve operational efficiency in embedded designs.

The PIC-IoT WG Development Board includes the Microchip ATWINC1510 Module, a single-band 2.4GHz network controller specifically optimized for low-power IoT applications. Featuring extremely low-power consumption, the ability to store various security certificates, and 8Mb of on-board Flash memory, the ATWINC1510 Module offloads all networking tasks from the main CPU while automatically providing a secure socket connection and server authentication to the Google Cloud.

The included ATECC608A CryptoAuthentication Device provides a trusted and protected identity for each device that can be securely authenticated. All ATECC608A ICs come pre-registered on Google Cloud IoT Core and are ready for use with zero touch provisioning.

The PIC-IoT WG Development Board is designed from the ground-up to take full advantage of Microchip MPLAB® X IDE (Integrated Development Environment) and MPLAB Code Configurator (MCC) Rapid Prototyping Tool. The Development Board is also compatible with more than 450 MikroElektronika Click boards™ that expand sensors and actuator options. Developers who purchase the kit will have access to an online portal for immediate visualization of their sensors’ data being published. Supported by complete board schematics and demo code, the PIC-IoT WG development board helps get customers to market quickly with differentiated IoT end products.
