Partial kit for the Wide-Range Ohmmeter
A set including the PCB, all SMDs and some other parts needed to build the Wide Range Ohmmeter.
See the parts list link below for details on what is included.
You will need to separately source the case, LCD (available from our shop), battery holder, relays, and some other standard through-hole parts like resistors, electrolytic capacitors, diodes and transistors. None of those parts should be too hard to find.
Note: photo shows assembled PCB including parts not included in this set.
