Did not come with a plastic case. Did not need to solder for my application. Ready to go. Just had to flash the software to it.

If you are new to mesh networks then this is a great starter device for you to get in. There are some other configuration and boards that might be more sought after, but the concept and functionality are virtually the same in that regards. Get a proper antenna for the function to get better results. This comes with an antenna that I suspect is properly tuned, though I have no way and no equipment to test the actual tuning of the included antenna. The kit comes with most everything you need to get started out of the box (minus another unit to communicate with). This is based on the ESP type chipset and PCB board configuration offered by Heltec. These things are great if used in a practical application. While they won't solve all your offgrid open source communication needs, they are fantastic in the sense that they do work for relatively long range applications.Using the Meshtastic app, you can create your own mesh network with more than one of these things. I've had successful connection with others like this in the Heltec variety that got a good range sending a text message from about 2miles away. Line of sight is key in getting the most optimal range on these type of devices.These are great for Meshtastic mesh networks, but you can adapt them to do many many other applications like for example controlling a remote (another one of this device) that might run relays, sensors etc, and report back... For example a farming application you could use these long distance and read data from sensors, like weather stations perhaps, or use one to control a watering system etc. They are virtually like Arduino microcontrollers that can handle a lot of various applications. These are also able to connect via wifi for expanding your connectivity, as well as bluetooth (ESP32 Chipset capability).This kit comes with a nice hefty battery, and a case that will fit only the module/board, so don't expect to have a case included that will accomodate the battery in a seamless form factor. This is where I design and 3D print my own casing for such accomodation to the included battery. There are many 3D print models out there if you are lucky to have a 3D printer.While the ESP32, and the Meshtastic means of utilizing a Mesh network are probably more for the more experienced people, especially if you get into C coding your own functionality for these controllers. There are software libraries that are available that will make this task relatively easier.

Now these can be programmed using a web client. So cool. And they work really damn well!

The kit was missing the case, and the proper antenna. The antenna provided was just a heat shrink wrapped wire.
