The two enormous (in comparison) black components on the right are the stand-in resistors, with their leads bent to fit the board's contact pads!
The component in the middle of these two is the high power header connector - you may remember that's the part I ordered in numbers way over the top, because actually you only needed one, which is broken into 4-way parts. The first go caused a 5-way part (!), so after that I tried needle-nose pliers (too wide), and then cutting the plastic with tin-snips. This worked a treat, but I was glad I was wearing eye protection because each cut part fired off, and bounced off 2 or 3 obstacles before disappearing! I would see where it went first and second and then lose it! Took me a while to find it, based on the landing noise it had made!
See the blue header at the bottom? That's the only one I have. Remember there are 3 stepper motors, and therefore 3 driver boards? Somehow I failed to order 3 of these headers!
So for future orders, so far, the list goes:
- 2 more headers, part 110-3949 from Farnell
- 1 more ceramic capacitor, 100 nF, part 165-0887 from Farnell
- and 1 green 1206 2 mm LED, which I might get from Farnell as well, say part number 1226372 at 6p.
So it will be a while before I finish these three stepper motor driver boards.
