Today I have tried to put together the first universal board using the stripboard template I've posted earlier. It is not the best soldering job, but ... I think it works I have attached some images of the process. Basicall, these were the steps taken: - fix drill template, mark holes with feltpen on paper, look at backside of stripboard and mark again (images hole1, hole2, hole3) - drill holes w/ 2.5MM drill, just throug the strips (images drill1, drill2, drill3) - fix the components template, using the PIC as guide (image comp) - solder the components; final result is in image uboard.jpg Regarding the order of soldering, I did some of the vias first (below the L298N) but when I put the L298N on, it melted trough some of the vias, creating a shortcircuit between +5V and GND. If you use a stripboard, do those later (it is a little difficult because there's not much space next to the L298N). Finally, I tested the voltages using the guide on the Wiki - they seemed alright. Since I have not been able to flash a PIC yet, I will have to wait and find out if it really works as it is supposed to, but so far I am confident. At least there was no smoke ... ;-) Joost https://reprap.org/forum/read.php?13,1842,1842#msg-1842 Wed, 20 May 2026 15:27:53 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,1842,1870#msg-1870 https://reprap.org/forum/read.php?13,1842,1870#msg-1870 bartlee45 Controllers Tue, 15 May 2007 22:20:14 -0400 https://reprap.org/forum/read.php?13,1842,1850#msg-1850 https://reprap.org/forum/read.php?13,1842,1850#msg-1850 en.wikipedia.org] which would save me to build the extruder - I can just press the filament throught the stripboard and extrude ABS ;-)
