Particle Argon IoT Development Board

Added to your shopping cart

The Particle Argon is an IoT development board that allows you to connect your mesh network to Wi-Fi. With the Nordic nRF52840 SoC and an ESP32 you have all the power of an ARM Cortex M4 with OpenThread mesh networking, Wi-Fi (b/g/n), NFC, plenty of GPIOs, LiPo charging and more. The board is designed to act as a standalone Wi-Fi endpoint or a Wi-Fi enabled gateway for a Particle Mesh network.

The Argon is also configured in the popular Feather footprint making it also compatible with Feather Shields! That means it includes a JST connector for a LiPo battery as well as charging of the battery over USB. Particle also provides an RGB status LED and a JTAG (SWD) connector for debugging and an onboard PCB antenna for your mesh network (you will need a U.FL antenna for NFC or Wi-Fi)

The Argon comes with access to the Device Cloud (10 free micro networks available) as well as three free months of device Cloud access using a cellular gateway. The Particle Could has some great features for building connected projects, including over-the-air firmware updates, and easy-to-use REST API, and firmware development supported by web and local IDEs.

Three Quick Tips About Using U.FL

December 28, 2018

Quick tips regarding how to connect, protect, and disconnect U.FL connectors.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
