## Description

The Particle Argon is a powerful Wi-Fi enabled development board that combines mesh networking and Wi-Fi over the 2.4 GHz band. It can operate as a standalone Wi-Fi endpoint or as a Wi-Fi gateway for a Particle Mesh network. Built around the Nordic nRF52840 processor, the Argon delivers excellent performance for IoT applications. It includes large-capacity flash, RAM, native USB support, and built-in Li-Po battery charging circuitry. All Particle hardware integrates with the Particle Device Cloud, providing over-the-air firmware updates, a REST API, and firmware development via web and local IDEs. Note: Breadboard and USB cable are not included. Key Features Dual Wireless – Wi-Fi (802.11 b/g/n) and Bluetooth 5 with mesh networking Nordic nRF52840 SoC – ARM Cortex-M4F @ 64 MHz with 1 MB flash and 256 KB RAM ESP32 Wi-Fi Coprocessor – Espressif ESP32-D0WD with on-board 4 MB flash, up to 150 Mbps Additional Storage – 2 MB SPI flash on-board 20 Mixed-Signal GPIO – 6× analogue, 8× PWM, UART, I2C, SPI Built-in Battery Charging – Integrated Li-Po charging with battery connector Security – ARM TrustZone CryptoCell-310 cryptographic module NFC-A Tag – Built-in NFC support Flexible Antenna Options – On-board PCB antenna plus U.FL connectors for external antennas (one for Thread/BLE, one for Wi-Fi) Compact Design – 51 × 23 × 15.5 mm, 8.8 g Specifications Processor: Nordic nRF52840 – ARM Cortex-M4F @ 64 MHz Wi-Fi: ESP32-D0WD – 802.11 b/g/n, up to 150 Mbps Bluetooth: Bluetooth 5 – 2 Mbps, 1 Mbps, 500 Kbps, 125 Kbps IEEE 802.15.4: 250 Kbps TX Power: Up to +8 dBm (down to −20 dBm in 4 dB steps) Flash: 1 MB (nRF52840) + 4 MB (ESP32) + 2 MB SPI RAM: 256 KB USB: Micro USB 2.0 full speed (12 Mbps) GPIO: 20 mixed-signal (6× analogue, 8× PWM) Interfaces: UART, I2C, SPI, JTAG (SWD) Certifications: FCC, CE, IC certified; RoHS compliant Dimensions: 51 × 23 × 15.5 mm Weight: 8.8 g Ideal For IoT prototyping and connected device development Wi-Fi gateway for Particle Mesh networks Battery-powered wireless sensor nodes Cloud-connected projects with OTA firmware updates Resources Quickstart Guide Datasheet
