Please make sure that the USBport is able to provided at least 500mA. Power from the USB is regulated down to 3.3V bythe on board Torex XC9258A step-down regulator.The pin is internally connected to the VBUS of the USB port. The nominal output shouldbe around 4.5 to 5 VDC when the device is plugged into the USB port and 0 when notconnected to a USB source. You can use this pin to power peripherals that operate at suchvoltages. Do not exceed the current rating of the USB port, which is nominally rated to500mA. This pin is also protected with an internal fuse rated at 1000mA.PowerUSB PORTVUSB PINLiPo
2018/11/15 Particle Datasheets | Argon datasheethttps://docs.particle.io/datasheets/wi-fi/argon-datasheet/ 4/22If you want to make your projects truly wireless, you can power the device with a singlecell LiPo (3.7V). The Argon has an on board LiPo charger that will charge and power thedevice when USB source is plugged in, or power the device from the LiPo alone in theabsence of the USB.NOTE: Please pay attention to the polarity of the LiPo connector. Not all LiPobatteries follow the same polarity convention!This pin is internally connected to the positive terminal of the LiPo connector. You canconnect a single cell LiPo/Lithium Ion or a DC supply source to this pin for powering theArgon. Remember that the input voltage range on this pin is 3.6 to 4.2 VDC.This pin is the output of the on board 3.3V step-down switching regulator (TorexXC9258A). The regulator is rated at 1000mA max. When using this pin to power otherdevices 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.

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 isrequired 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 PCBantenna which is selected by default in the device OS and a u.FL connector if you wish toconnect an external antenna. If you wish to use the external antenna, you'll need to issuean appropriate command in the firmware.Mesh and WiFiParticle Device Frequency Antenna Type Manufacturer MFG.

2018/11/15 Particle Datasheets | Argon datasheethttps://docs.particle.io/datasheets/wi-fi/argon-datasheet/ 17/22The Argon contains highly sensitive electronic circuitry and is an Electrostatic SensitiveDevice (ESD). Handling Argon without proper ESD protection may destroy or damage itpermanently. Proper ESD handling and packaging procedures must be appliedthroughout the processing, handling and operation of any application that incorporatesArgon. ESD precautions should be implemented on the application board where theArgon is mounted. Failure to observe these precautions can result in severe damage tothe Argon!There are four connectors on the Argon that will get damaged with improper usage. TheJST connector on the circuit board, where you plug in the LiPo battery, is very durable butthe connector on the battery itself is not. When unplugging the battery, take extraprecaution to NOT pull the connector using the wires, but instead hold the plug at its baseto avoid putting stress on the wires. This can be tricky with bare hands - nose pliers areyour friend here.Product HandlingESD PrecautionsConnectors
2018/11/15 Particle Datasheets | Argon datasheethttps://docs.particle.io/datasheets/wi-fi/argon-datasheet/ 18/22The micro B USB connector on the Argon is soldered on the PCB with large surface padsas well as couple of through hole anchor points. Despite this reinforcement, it is very easyto 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 allthe gold plating). The connector was not designed to be constantly plugged andunplugged. Care must be taken not to put stress on it at any time (yes, swinging the Argonby the antenna is a very bad idea, this is not your cat). The antenna pin is also the moststatic sensitive and you can destroy the radio with improper handling. If you are feelingadventurous, 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 isinserted improperly. If you are trying to debug the device, you probably are not in a goodmood 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!The breadboard provided with the Argon is specifically designed to require low insertionforce. This makes it easy to plug the Argon in and out of the breadboard. If you end upusing 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).Breadboarding
2018/11/15 Particle Datasheets | Argon datasheethttps://docs.particle.io/datasheets/wi-fi/argon-datasheet/ 19/22The 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 tovery easily toggle digital pins, take analog and digital readings and drive variable PWMoutputs.The bootloader allows you to easily update the user application via several differentmethods, 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.Federal Communication Commission Interference Statement This equipment has beentested and found to comply with the limits for a Class B digital device, pursuant to Part 15of the FCC Rules.
