It can handle input between 9V and 36V and put out between 5 and 5.3V depending on the power you put into the module. I have an Arduino mega that will manage with relay a 12v alimentation with relay for LED light and I want to dedicate this electricity to the Arduino to avoid to add an charger. In general, it should be noted that the cheaper the product the more likely it is to be of poor quality. You should consider your budget and stretch it as much as possible to get the best possible converter. Here, Vout is the output voltage taken across resistor R2. Vin is the input voltage to be step down. Choose the standard resistor value (greater than 1K Ohm) of anyone resistance and solve for the other one. Then choose the standard value nearest to the obtained value of the resistor. Anybody know the actual pad dimensions for us non-Eagle users? I don't have it yet but want to begin laying out a board, and I would rather not guess. Thanks.

That tiny footprint saved me. Like I mentioned earlier, there are 9 TO 220 transistors, three with their own heatsinks, six more bonded to a common sink, 9 screw terminals for wiring the MOSFETs to their coil leads all crammed on a tiny business card sized computer development proto board. One consideration that must be taken into account if this level shifter is used for i2C, which requires pullup resisters for the BUS. And that is the resulting pullup resistance in the I2C BUS. This circuit also has the capacity to give the same output current as taken from an unregulated source. Naturally converters aimed at 1-2A loads perform worse in this scenario, which is exactly what I was trying to show. However, what if you have a 12 volt power supply available? There are plenty of batteries that offer just 12 volts and you can even get transformers that reduce your home supply to 12 volts. The good news is that you can get a 12V to 5V converter, you simply need to choose the right one. Best 12 Volt to 5 Volt Converters Drok 12v to 5v Converter Drok 12v to 5v ConverterIn short, if it is designed to handle 5 volts, you need to make sure it is getting 5 volts. Of course, the domestic supply is different depending on where you are in the world. The US and Canada have 120 volts. In contrast, the UK uses 230 volts.

Can we use this board in between my MCU and GSM modem to shift UART voltage level? My baudrate is 115200. Few points worth mentioning: first, the “Cigar”, with its fixed USB output connector is providing voltage that is too high by proper USB standards. It could be due to old age or just bad quality. The difference is about 10% and I would consider it not usable. Second, most modules are capable of input voltages up to about 25 volts, but few can do 40 volts and higher. Kudos for that. Switching circuit properties Module Here is the 12v to 5v dc converter circuit for low current applications (< 70 mA), mainly for taking reference signal/ voltage and in a small current draining circuit like an LED indicator. Hi Dan, I am not sure I know how to help you. Perhaps test the resistance of the solenoid and compare it to the expected value using your data and the V=IR formula.Most of my Arduino type boards are 5V although many do have 3.3V available. Nevertheless, with this converter it is easy to wire up 3.3V devices to 5V. BTW. in my hands “Fine” didn’t have any ripple at all (< 30 mV up to 900 mA, did not yet test higher currents). I will look into it again to be sure it was a decent measurement. For Fine the minimal input voltage was 6.4V (to obtain an output of 5.1V). Would this work to connect a 12V RS232 with 3.3V logic? What is the highest voltage it can support? This board will also work great for converting 3.3V or 5V PWM to 10V PWM for use with things like the the dimming control on MeanWell LED power supplies.
