Power Supply 3.3

USB IO Board is breadboard compatible. Page: 12345678910...24Next Select ImageMouser Part # Mfr. Lastly there’s the output section, but there’s nothing particularly exciting going on there. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors. my review here

Eventually, the resistance is very high, so the current is very low. Putting a header on the switch would not give you access to two outputs. Technobly / about 6 years ago / 2 / Because they plugged it in at the bottom of the board for the picture! But I threw this in with one of my orders and I’m loving it. https://www.sparkfun.com/products/114

tia saccade / about 6 years ago / 1 / @c47334, @Maragnus: thanks for the heads up about the blinding LED - I replaced it with something calmer. @Nate & Co: Kamiquasi / about 4 years ago / 2 / In general, I would check for shorts or bad solder joints. Part # Mfr. I connected it properly and it was like sharp doesnt supplied porperly because nothing was on the serial monitor.

Most of the true LDOs have more than three terminals: Input, adjust, ground, enable, and output. Please try your search again. I would be interested in hearing from others how they installed this piece. PRT-13157 This is a very simple board that takes a 4-9V input voltage and outputs a selectable 1.8V or 3.3V regulated voltage.

I want to make a solar powered cell phone charger using a panel I have laying around. The selected filters are no longer available and the search results have changed. The little module may look tiny but inside is a high efficiency converter (up to 91%) which can output 1 Amp at 3.3V with up to +60°C ambient temperature without the http://www.banggood.com/buy/3.3v-power-supply.html However, this voltage may also be available in our AC-DC wide adjust output power supplies.

Actually, does it even need the fuse? Generated Fri, 20 Jan 2017 10:24:44 GMT by s_hp87 (squid/3.5.23) In a nutshell, the bigger the difference between Vin and Vout, the hotter the regulator will get under the same current draw. Multimeter reads 5.05V and 3.28V well within the tolerances of this circuit.

  • I have a different breadboard so I’m personally going to use a female header facing upwards so I can just connect it with wires.
  • Good job guys ..
  • And is this safe for a phone?
  • The datasheet says the max Vin - Vout = 37V, so it should theoretically work on 24V.
  • Easy to assemble.
  • Member #330558 / about 5 years ago / 1 / What’s the minimum input for this board?
  • For best results, please make sure your browser is accepting cookies.
  • Member #770060 / last year / 1 / I just assembled this, and it isn’t working.
  • Normally the combination of the 390 Ohm / 240 Ohm, or (390 Ohm + 330 Ohm) / 240 Ohm, are what set the voltage (nearly 3.3V, and 5V respectively).

Plug the 9 volt battery clip onto a standard 9V battery and connect the other end to anyt… $ 2.95 1 Favorited Favorite 10 Wish List Added to your cart! SparkFun Recommended SparkFun Breadboard Power Supply Stick - 3.3V/1.8V Only 3 left! The meter uses PIC16F876A microcontroller with 16x2 backlighted LCD. 60MHz Frequency Meter / Counter Frequency Meter / Counter measures frequency from 10Hz to 60MHz with 10Hz resolution. BA1404 HI-FI Stereo FM Transmitter broadcasts high quality stereo signal in 88MHz - 108MHz FM band.

So it looked like it wasn’t working until I put my jumpers into the correct holes. this page The ability to select 3.3 or 5 volt output is a big plus, and I like the way it plugs directly into the breadboard. Can be cut to size with a pair of wire-cutters. Pay attention to the picture and the on-board documentation, make sure you orient your caps and diodes and LM317 correctly, and this will make a great first/early soldering project which coincidentally

It's the Arduino Pro Mini! It went together in about twenty minutes and worked perfectly. USB IO Board USB IO Board is a tiny spectacular little development board / parallel port replacement featuring PIC18F2455/PIC18F2550 microcontroller.

The kit worked like a charm, only observation I can make is that it won’t work with a wall wart with an output of less than 9V, it won’t even turn

Not that it’s difficult to make a simple 5V regulator, it’s just nice to have a good looking PCB. So, pro tip: study the anatomy of your breadboard before testing.l Draco Carathyr / about 3 years ago / 1 / I have only used this for less than 2 hours Thanks SparkFun for such a good kit. :) Kha0stickler / about 7 years ago / 1 / Just received mine today, took 15 minutes to assemble. These DC/DC converter step-down switching regulators are drop-in replacements for inefficient 78xx linear regulators.

Need Help? The silk screen was very informative and greatly aided assembly. As a beginner, I have no idea why it doesnt… =( Thanks for your help :)) DonGar / about 3 years ago / 1 / What’s a reasonable load for this http://wphomeguide.com/power-supply/not-sure-about-power-supply.php If you look at the schematic, you’ll see that your power supply input goes through a diode (with a small voltage drop), and a PTC resettable fuse (with a negligible drop

It’s rather straight forward and easy. kaoD / about 6 years ago / 1 / I suppose you switched the 330 and 390 resistors of the LM317, not the 330 current-limiting resistor of the LED. Maragnus / about 8 years ago / 7 / This is fantastic. Kevin Vermeer / about 5 years ago / 1 / Soldering a piece of wire across the legs of the PTC is not safe.

First time soldering, but I managed to keep the contacts separate even on some of the close ones. Biscuit / about 6 years ago * / 1 / Echoing the above comments, got it today, 45 mins assembly (only because I wasn’t 100% on a couple of things), powered I’m jazzed!!!! When I test it with a 9v, 800mA power supply, I get 8v out of the kit.The voltage coming out from the kit doesnt change if I switch 3,3v/5v.

Thanks for the great kit! A good buy about 2 years ago by Member #411720 verified purchaser It was easy to assemble and does what it is designed to do. If it were any brighter, I’d be blind. Very much an electronics noob….but this might be perfect for an idea I got brewing.
