UNBProbe is a passive, spring-loaded needle probe for probing PCBs. The spring loaded needle can be removed from its receptacle to allow for different types of probe tips. The PCB contains two solder jumpers and pads for two 0402-sized surface-mount components near the tip. It contains a header for jumper wires and an SMA Connector rated for a frequency range up to 26.5 GHz. Full documentation is currently under development.
