Poor man's piggyback ISP

prusaprinters

Use this quick print adapter to connect male Dupont pins to a DIP-packaged IC's pins on the fly. Meant for in-system-programming (ISP) AVR microcontrollers, but surely there are other uses, e.g. in-circuit testing with logic analyzers etc. Comes in versions for 8, 14, 16, 20 and 28 pin DIP packages. Write in the comments or send me a message if you need others. Usage: Simply clip it on top of your PCB mounted IC and push in your Dupont connectors wires where you need them. You'll need a tiny bit of force, as the adapter is designed to firmly press the contacts against each other. That's why I don't recommend using plain jumper wires, they are often too feeble and will slide out of their housing. Important: Be careful upon removal of the adapter, or you might remove the IC with it (and bend its legs etc.). Best use a wedge shaped tool like pincers and gently push it in between the top of the IC and the adapter, working from both ends until it pops off. Print Settings Printer: Creality Ender 3 v2 Rafts: No Supports: No Resolution: .12mm Infill: 100% Filament: any any any Notes: There's little room for tolerances as we need to get a tight, but not too tight, contact between Dupont and IC pins. So if you're print comes out too loose or too tight, play around with the usual settings like*Hole horizontal expansion*, flow rate etc. to adapt the holes' widths. Category: Electronics
