An ON/OFF switch and a 3.3/5V switch make it very versatile. And the power status LED let's you know right away whether the board is live or if it's safe to connect/disconnect parts. However, the product description does not include the max current the board will support. Mention is made of the "TO-220 Voltage Regulator (LM317 1.5A max current)" which led me to believe I was getting a 1.5A power supply. But the board as a PTC (Positive Temperature Coefficient) fuse that, according to the schematic, limits the current to 500mA and, according to the Sparkfun page for the component, COM-08357, limits the current to 250mA. I'm thinking of just shorting out the PTC fuse with either a wire or a replaceable fuse holder with a 1 to 1.5A fuse in it, but I haven't researched this yet. In particular, it is not clear from the description if all the components can handle 1.5A or if it's just the LM317 regulator. 1 of 1 found this helpful: Like it! about 2 years ago by Member #758164 verified purchaser Works as advertised. Easy to assemble. Was missing the 330 Ohm resistors and one switch was faulty so I could only get 5V out of it. Works 100% about 3 years ago by Member #330549 verified purchaser Works great so far! Very handy for breadboard projects about 2 years ago by Member #450662 verified purchaser more time spent playing with circuits, less time worrying about power conditioning! Equal to Tylenol! about 2 years ago by Member #732434 verified purchaser Been playing around with a Pickit 3 for a while, always have programming issues. Ran a voltmeter across the powers and discovered Pickit 3 doesn't always supply the best voltages. Bought this little guy, shipping was a bit pricey for being USPS, especially for a kit and coming from Colorado to Nebraska. After assembly and a couple more hours of banging head on table, I was finally able to program my PICs without problems. So proud of myself! make one change and add an option about 2 years ago by Member #471295 verified purchaser Modify the lone pair of pins that have no connection (NC)to have a direct connection to the DC from the wall wart. Add another product that has the exact part count except for the circuit board and the switches. I would then order the first for breadboarding and the second for any projects that I build after that. Great power supply, easy to assemble about 2 years ago by androticus verified purchaser Gee, I haven't soldered a circuit board for over 25 years (I started when I was 3 yrs old, lol...) but this was easy enough. The 1/16W resistors are virtually impossible to decode, so you might want a multi-meter to be sure which are which. I would suggest to not solder the parts in their order though - go from smallest (the resistors) to the bigger parts. I used little pieces of painter tape (the blue stuff, masking tape would work too) to keep the parts in place on the board while I soldered them. Another tip, do the header pins last - plug the pins into an actual breadboard in place, put something small as a spacer under the other side of the board to make it level, then tape it down solidly to the breadboard, then solder the pins. I built 2 and both worked presto whizzo. Great little kit last year by Member #513270 verified purchaser Very easy to put together and power your project. Missed being 5 stars by not having the parts labeled in the bag (at least for the educational aspect of it) and if there was a way to tap into both 3.3 and 5v with an extra set of headers before the regulator would make it a solid 5 stars. Very handy for powering breadboards about 3 years ago by imabug verified purchaser Super easy to assemble and provides either 3.3V or 5V to the power rails on your bread board. You'll lose a bit of breadboard real estate in order to properly support the module, but it's pretty easy to deal with. Breadboards are modular! That PSU is great! about 2 months ago by Member #1259366 verified purchaser That PSU has the most stable voltage output I have ever seen. Also easy to build. A good buy about 3 years ago by Member #411720 verified purchaser It was easy to assemble and does what it is designed to do. START SOMETHING. SUBSCRIBE TO NEWSLETTER In 2003, CU student Nate Seidle blew a power supply in his dorm room and, in lieu of a way to order easy replacements, decided to start his own company.
