Both 5v and 12v gnd are connected to each other. Feeding the ledstrips with the + 12v28A and using the irf540 mosfet to drain. (So feeding the ProMini at the Raw input with 12v28A and using the ProMini 5v output for the RTC and LCD. Which reminds me, I also have an RTC & LCD running at 5v not 12v )-: ![]() This is a 5V Arduino running the 16MHz bootloader. This way, the Pro Mini will draw whatever current it needs (not much) and the LED strip will draw what it needs (plenty) without all that current going through the Pro Mini. Its blue Its thin (0.8mm) Its the Arduino Pro Mini SparkFuns minimal design approach to Arduino. There are no connectors attached - allowing you to add whatever connectors or wire you want without too much. It's essentially a 5v Arduino that runs an 16 MHz bootloader on a super small, super thin board. Have the - side of the power supply go to the Pro Mini AND the LED strip. Adafruit Industries, Unique & fun DIY electronics and kits Arduino Pro Mini 328 - 5V/16 MHz : ID 2378 - The Arduino Pro Mini is SparkFun's minimal design approach to Arduino. ![]() Should I power RF with directly Vcc pin or use 3. Output voltage of Vcc pin of the pro mini is 5v. It has 14 digital input/output pins (of which 6. The board comes with built-in Arduino bootloader. have the + side of the power supply, whatever it is, go to the Pro Mini AND the LED strip. Hi, I am using Nrfr4l01 module with Arduino pro mini. Arduino Pro Mini is an ATmega168 based microcontroller board. Mind you, theres no headers and USB interface. Powering the Pro Mini with a 12V 1200mA power supply AND having the Pro Mini power the LED strip WILL cause problems. Try this the super-flat SparkFun Arduino Pro Mini, featuring a full 5V design running a ATMega328 at 16MHz. In some cases it may even work without the logic level converter, but theres no guarantees that it will continue to work if for example your. Powering the Pro Mini with a 12V 120A power supply is safe, since current is pulled, not pushed. Control other devices from an Arduino: For devices that do not draw a noteworthy amount of current, you may use an Logic level converter, typically to interface an 5V Arduino with an 3.3V Arduino. ![]() Reading THIS while typing my question is probably also my answer. My question, is it wise to feed the Mini Pro with a 12v x? Amps adapter like these ? Reading about the raw input for the mini pro I know it's possible to feed 12v, but my 12v for the ledstrip(s) gives alot of amps. (irf540 100V 28A)Įverything works like I want but now trying to design my first pcb and that reminded me of the two power supplies.would be great if I could use one instead. 5v for de mini pro and 12v for the ledstrip drived by pwm and a (2x) mosfet.
