I have developed the Picstep version 4 board but i did not install the IDC cable as my BOB only requires STEP and DIR signals. Today i accidentally reversed the Logic voltage cables so that instead of installation of +5V DC wire to the +5V Logic i install the +5V to the Gnd... The result was my PIC become too hot as soon i realize what i did wrong i removed the cables...
Fortunately most of the capacitors are ceramic or MKT type (non polar) so i am not worried about them But:
1- I am sure that the PIC is blown away.
2- What components else might be blown away?... XTAL and LMD?????
Anyone can tell me should i replace all the components and discard them? Or should i replace the 20MHz XTAL?
