+The pcb on itself is a ESP8266 with no sensors or battery. You need to manual solder a battery and sensor of your choice to the pcb.
 
 ## Original usage
 These pcb's where originally designed for virtual reality fullbody tracking. They are basicly movement trackers that can be used to track the movement of the body. We can also use this really well for our project.
