Using this ESP8285 SMT module is a great way to add Internet connectivity to your projects. First, if you're new to soldering, take your time when hand - soldering the module as the pads are large and easy to work with. Once soldered, since it comes pre - programmed with the NodeMCU Lua firmware, you can start testing it out. But remember, you'll need some extra components. Check out the HUZZAH schematic to see what parts you'll need to get the module up and running. As for maintenance, keep it in a dry and clean environment. Avoid exposing it to extreme temperatures or humidity as this could damage the internal components. Also, be careful when handling it to prevent static electricity from harming the sensitive electronics. Since this product is mainly for advanced users, if you find it too difficult to use, you might want to consider the Huzzah ESP8266 Breakout instead.
