No such luck I am afraidI thought the Farnell kits did this as standard?
Seems a shame as I don't think anyone would mind the extra pence to have a few spare in the kit.
Yup. Did the same!ChrisMc wrote:I managed to take the end off the 100uF capacitors when I was trying to tidy up the solder job
Luckily, on a whim, I had bought a 'sample' book of all sorts of values of SMD resistors and capacitors from a Chinese ebay seller (search ebay for #smd sample'), so I could just hoik one out of there!I'm pretty sure if someone started a kit, with two spare of all the surface mounted stuff on ebay, they might be popular.
Cautionary tale:davej wrote:Post-assembly voltage question:
Assembled, but the voltages at the regulator are out of whack and I have therefor not installed the jumper to feed the board itself.
RPI 5V in : 4V8
RPI 3V3 in: 3V3
Regulator out : 4V3
Is this just a 'no load' issue, or have I gone and messed something up ?
That should not cause a short as the copper is covered with a solder mask.C1 has some copper running between the two mounting pads, so if your assembly is slightly off you run the risk of bridging to the copper in the middle.
That is possible. All I finally noticed was a bad solder job by me (too much solder and component off-center). Fortunately I have two soldering irons so I was able to use a chopstick approach to remove the capacitor.Gert van Loo wrote:That should not cause a short as the copper is covered with a solder mask.C1 has some copper running between the two mounting pads, so if your assembly is slightly off you run the risk of bridging to the copper in the middle.
Unless you damage the solder mask by scraping it with a metal object (e.g. a soldering iron)
I mention this just in case. One or two people have had issues with the battery in their multimeter being a bit run down, which sometimes gives erroneous readings. Before assuming you've messed up, it might be worth checking that first. You never know. It could just be that.davej wrote:Original question: Got an unexpected high voltage (4V3) on the headers where I was supposed to get 3V3 on the output side of the regulator.
What would have been the best debug approach ?
Absolutely - it's practical, it's interesting and it's fun if you like that sort of thing, and it doesn't break the bank.Yewberry wrote:There's something utterly benign and wonderful about all this Pi stuff, you know
