USB port
This connector is used to upload code into Waspmote with a male to male USB cable provided by Libelium. Also, Plug & Sense! sends messages via this USB port. Just connect one side of the cable to this connector, removing protection cap and connect the other side to a PC to upload a code or to charge the internal rechargeable battery. Next picture shows an example.
When uploading processes are finished, do not forget to screw firmly the protection cap to avoid connector damage. Never connect a USB which exceed maximum ratings of USB standard.
For indoor deployments the nodes can be recharged using the USB charger and the regular USB cable.
Outdoors USB Cable
The Outdoors USB Cable is made for outdoors applications with high power consumption requirements, where nodes need to be permanently powered. It consists of a 3-meter cable with the solar socket connector on one end, and a USB male A type on the other end.
The solar socket end is meant to be connected on the solar socket of Plug & Sense!, it is not valid for the sensor sockets. This special end is waterproof and suitable for outdoors connections.
On the other hand, the USB end of the cable is thought to be connected to the USB charger (AC/DC, 5 V output). Bear in mind that this end is not waterproof so it cannot be used outdoors. Please protect it accordingly.
One application of the cable is to power a node placed on the facade of a building; the USB cable goes indoors through a nearby window, and the USB end remains indoors, connected to a wall adapter.
External SIM/USB socket
The External SIM/USB socket replaces the USB socket in 2 types of devices:
Waspmote Plug & Sense! devices with 4G module or NB-IoT / Cat-M module
Meshlium devices with 4G module
The External SIM/USB socket is composed of 2 connectors:
nano-SIM card
micro-USB (type B)
The operation with the micro-USB socket is just the same as with the normal USB socket. Just remember to use a micro-USB cable.
The nano-SIM card connector allows the user to connect the SIM card he likes from the outside. It is not necessary to send a SIM card to Libelium for proper installation. You can ask your telecommunication provider for a nano-SIM card. Alternatively you can take a normal SIM card and transform it into a nano-SIM card with a SIM card cutter.
Besides, the nano-SIM card connector has a push-push mechanism, so it is really easy to remove the card with the aid of one nail.
Bear in mind that the SIM card does not disappear inside the socket: there is always a tail of ~2 mm outisde, so you can push the card with your nail in order to remove it.
Please mind the correct orientation of the nano-SIM card: the side of the chip must look towards the micro-USB connector, and the 45º-angled corner must face the device.
It is highly important to turn off the Plug & Sense! device in a secure way before inserting a SIM card, or removing an existing SIM-card. The user can damage the device if this operation is done "on-the-fly".
Make sure you closed the External SIM/USB socket with its protection cap before outdoors deployment.
Take into account that the External SIM/USB socket has a limited resistance so please be gentle and do not push too hard with the USB or SIM card.
From February 2018, Libelium has redesigned the SIM-USB connector, now it is more resistant and we have updated it using the most popular SIM card standard, nano-SIM.
