Frequency Probe 2

This is the next step in evolution of the original  Frequency probe with its sleek case which adds measuring of crystals / resonators with out building oscillator circuit right on the probe. Other significant change is the use of ATtiny414 microcontroller in place of the ATtiny84



 

Case / 3d files
Case for the probe remins the same with bottom part being part of  logic probe  and with small alteration to the upper case from frequency probe adding oppening for 1x3 0.1" header where the crystal socket is located



Versions of the boards are available on our Tindie store
