Hello guys,
I just received my new pcb design from pcb-pool and soldered most of the components on.
Though I am still waiting to solder the two chips I have as the pins are small and I want to check that the other parts of the circuit is working first.
The first thing I did was to solder on my 9v battery clips to the vdd and gnd. The 9v battery is actually showing about 7v though when I connect it I get around 2v on the meter!?
I tested the battery again by itself and I get around 7v but as soon as I put the clip on and test the same battery terminals I get 2v!?
Can someone tell me what I'm doing wrong?
