2018/11/15 Particle Datasheets | Argon datasheet !"#$% & ' ()**'% +,--./ DOWNLOAD PDF Functional description Overview The Argon is a powerful Wi-Fi enabled development board that can act as either a standalone Wi-Fi endpoint or Wi-Fi 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. https://docs.particle.io/datasheets/wi-fi/argon-datasheet/ 1/22

2018/11/15 Particle Datasheets | Argon datasheet The Argon is great for connecting existing projects to the Particle Device Cloud or as a gateway to connect an entire group of local endpoints.

2018/11/15 Particle Datasheets | Argon datasheet Power USB PORT The USB port is the easiest way to power up the Argon. Please make sure that the USB port is able to provided at least 500mA. Power from the USB is regulated down to 3.3V by the on board Torex XC9258A step-down regulator. VUSB PIN The pin is internally connected to the VBUS of the USB port. The nominal output should be around 4.5 to 5 VDC when the device is plugged into the USB port and 0 when not connected to a USB source. You can use this pin to power peripherals that operate at such voltages. Do not exceed the current rating of the USB port, which is nominally rated to 500mA. This pin is also protected with an internal fuse rated at 1000mA. LiPo https://docs.particle.io/datasheets/wi-fi/argon-datasheet/ 3/22

2018/11/15 Particle Datasheets | Argon datasheet If you want to make your projects truly wireless, you can power the device with a single cell LiPo (3.7V). The Argon has an on board LiPo charger that will charge and power the device when USB source is plugged in, or power the device from the LiPo alone in the absence of the USB. NOTE: Please pay attention to the polarity of the LiPo connector. Not all LiPo batteries follow the same polarity convention! Li+ PIN This pin is internally connected to the positive terminal of the LiPo connector. You can connect a single cell LiPo/Lithium Ion or a DC supply source to this pin for powering the Argon. Remember that the input voltage range on this pin is 3.6 to 4.2 VDC. 3V3 PIN This pin is the output of the on board 3.3V step-down switching regulator (Torex XC9258A). The regulator is rated at 1000mA max. When using this pin to power other devices or peripherals remember to budget in the current requirement of the Argon first. This pin can also be used to power the Argon in absence of the USB or LiPo power. When https://docs.particle.io/datasheets/wi-fi/argon-datasheet/ 4/22

2018/11/15 Particle Datasheets | Argon datasheet powering over this pin, please connect the ENABLE pin to GND so that the on board regulator is disabled. Antenna There are two radios on the Argon. A Mesh radio (nRF52840) and a WiFi radio (ESP32). For the WiFi radio, we have provide a u.FL connector to plug in the WiFi antenna. This is required if you wish to use the WiFi connectivity. There are two options for the Mesh antenna on the Argon. It comes with an on-board PCB antenna which is selected by default in the device OS and a u.FL connector if you wish to connect an external antenna. If you wish to use the external antenna, you'll need to issue an appropriate command in the firmware. FCC approved antennas Mesh and WiFi Particle Device Frequency Antenna Type Manufacturer MFG.

2018/11/15 Particle Datasheets | Argon datasheet Product Handling ESD Precautions The Argon contains highly sensitive electronic circuitry and is an Electrostatic Sensitive Device (ESD). Handling Argon without proper ESD protection may destroy or damage it permanently. Proper ESD handling and packaging procedures must be applied throughout the processing, handling and operation of any application that incorporates Argon. ESD precautions should be implemented on the application board where the Argon is mounted. Failure to observe these precautions can result in severe damage to the Argon! Connectors There are four connectors on the Argon that will get damaged with improper usage. The JST connector on the circuit board, where you plug in the LiPo battery, is very durable but the connector on the battery itself is not. When unplugging the battery, take extra precaution to NOT pull the connector using the wires, but instead hold the plug at its base to avoid putting stress on the wires. This can be tricky with bare hands - nose pliers are your friend here. https://docs.particle.io/datasheets/wi-fi/argon-datasheet/ 17/22

2018/11/15 Particle Datasheets | Argon datasheet The micro B USB connector on the Argon is soldered on the PCB with large surface pads as well as couple of through hole anchor points. Despite this reinforcement, it is very easy to rip out the connector if too much stress is put on in the vertical direction. The u.FL antenna connector is a very fragile piece of hardware ( and is fancy too with all the gold plating). The connector was not designed to be constantly plugged and unplugged. Care must be taken not to put stress on it at any time (yes, swinging the Argon by the antenna is a very bad idea, this is not your cat). The antenna pin is also the most static sensitive and you can destroy the radio with improper handling. If you are feeling adventurous, we highly recommend putting a tiny dab of glue (epoxy, rubber cement, liquid tape or hot glue) on the connector to securely hold the plug in place. The 10 pin SWD connector provides an easy in-system debugging access to the device. The pins on the connector can easily be damaged if the mating connector cable is inserted improperly. If you are trying to debug the device, you probably are not in a good mood to begin with. The last thing you want is to render the connector useless. Be nice, and be gentle on the connector. Good luck with the debugging! Breadboarding The breadboard provided with the Argon is specifically designed to require low insertion force. This makes it easy to plug the Argon in and out of the breadboard. If you end up using a different breadboard, remember that it may require more force. In this case, always remember to pinch-hold your precious Argon by the sides (along the header pins) when plugging-unplugging and not by the USB connector (don't be this person). https://docs.particle.io/datasheets/wi-fi/argon-datasheet/ 18/22

2018/11/15 Particle Datasheets | Argon datasheet Default settings The Argon comes preprogrammed with a bootloader and a user application called Tinker. This application works with an iOS and Android app also named Tinker that allows you to very easily toggle digital pins, take analog and digital readings and drive variable PWM outputs. The bootloader allows you to easily update the user application via several different methods, USB, OTA, Serial Y-Modem, and also internally via the Factory Reset procedure. All of these methods have multiple tools associated with them as well. FCC IC CE Warnings and End Product Labeling Requirements Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1.
