I have a PIC18F14K50 with a Microchip PICKit2 and the development board pictured below:
Up until now, I've been using the board only for programming using the power supplied by the USB/PICKit, however now I need to use the board a little more permanently as I'm using 12Mhz at 4x for USB and my breadboard has some issues at those frequencies.
I can put my IO Expanders and other supporting components onto this board, however I need external power (5V) to drive everything. USB doesn't supply enough current to run my whole setup.
I originally supplied my +5V to pin 1 circled in yellow, and GND to pin 20 also circled in yellow. When I connected my PICKit to the ICSP1 (green circle), it burnt out my PICKit. I have since bought a new PICKit but I need this external power working.
I noticed the red power header, circled in red. I imagine these are just direct connections to pins 1 and 20 on the MCU, so I'm not sure how these would be any different to supplying power to the yellow circles.
How/where should I be connecting my external +5V such that it doesn't blow my PICKit? Thanks.
