IntroductionThe Particle Argon, Boron, and Xenon are Particle IoT dev boards with mesh networking. All the boards are all built around the Nordic nRF52840 SoC and include an ARM Cortex-M4F with 1MB of Flash and 256k of RAM. This chip supports Bluetooth 5 and NFC. The Argon adds WiFi with an ESP32 from Espressif and in this project, how to setup Argon along with controlling LED’s using webpage and Argon is discussed in a detail.

Components Needed
Particle Argon ==> $28
Breadboard ==> $6
LED’s ==>$2

The Argon is a powerful Wi-Fi enabled development kit that can act as either a standalone Wi-Fi endpoint or WiFi enabled gateway for Particle Mesh networks. It is based on the Nordic nRF52840 and has built-in battery charging circuitry so it’s easy to connect a Li-Po and deploy your local network in minutes.
