Particle Argon - a module with WiFi for the Mesh network

Description

Particle Argon is a small evaluation board with nRF52840 (ARM Cortex-M4) and WiFi ESP32-D0WD module. Argon is a powerful set that supports Wi-Fi connections, which can act as a standalone Wi-Fi endpoint or a Wi-Fi gateway in Particle Mesh networks. The module includes a system from Nordic Semiconductors (nRF52840), BLE Cortex M4 with lots of Flash, RAM and peripherals, including native USB support. The set will be used in IoT networks and projects using data stored in the cloud.
