Particle Argon (Wi-Fi + BlueTooth + Mesh)

The Particle Argon is a powerful Wi-Fi development kit that you can use as a standalone Wi-Fi device or Wi-Fi enabled gateway, repeater, or endpoint for Particle Mesh networks.

Equipped with the Nordic nRF52840 and Espressif ESP32 processors, the Argon has built-in battery charging circuitry which makes it easier to connect a Li-Po battery and 20 mixed signal GPIOs to interface with sensors, actuators, and other electronics.
