PIC ICSP Instant SMD Connector with Pogo Pins [ PCB Heaven - New Project]

Sat, 5 May 2012 16:23:34 -0400

Some time ago i began replacing my chips and other electronic parts with SMDs, including the PIC microcontrollers. To program the microcontroller i had to add a through-hole or SMD connector with 5 pins, but this actually had much larger footprint than the PIC itself. So i decided to design a pogo-pin ICSP connector and an SMD Eagle library to print the ICSP pads on the PCB directly!
