#ARDUINO NANO SCHEMATIC CRYSTAL OR RESONATOR PRO#

Some of the Arduino Pro Minis come with MHz and V markings on the back. (no limit or warranty for these details.) Voltage regulators: KB50, L05, L0UA, L0UB.Voltage regulators: KB33, S20K, F34V, L0RA, L0RB.

You don't want to use the method above for some reasons? Then you need sharp eyes and some luck that the following list includes you components (some of these are collected from the other posts, some of them from my Arduinos): It lacks only a DC power jack, and works with a Mini-B USB cable. It has more or less the same functionality of the Arduino Duemilanove, but in a different package. For instance, one of my 5V Arduino Pro Minis looks like this, but also has RAW-, VCC- and GND-labels (just one of the GND pins is at a different position, make sure you check your Arduino pin-labels): The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x).

One GND pins to the GND of the power source and one GND pins to the GND of the multimeter (you can take any of the Arduino pins labeled with GND)ĭon't worry if your Arduino looks a little bit different, just look for the pin labels.

VCC multimeter ( 5V = 5V Arduino, 3.3V = 3.3V Arduino).

These two capacitors which are about 220nF plus the crystal oscillator (16MHz) provide the correct timing for the arduino. The two capacitor symbols are shunt to ground to reduce noise and provide resonator stability. I've done a short sketch of how you should connect your Arduino Pro Mini: The resonator is actually the circuit comprised of the crystal on the left and R2 on the right. There is no reason why this would kill your Arduino (in case your Arduino isn't broken - which would be good to know anyway and of course you shouldn't short anything). I think the safest way is just connecting a voltage in the range of 6V-12V to the RAW-pin and measuring the (regulated) output of the VCC-pin. But why? It is complicated (you need to connect the USB-TTL-converter to each of the different Arduinos and sometimes they have different pinouts, so it's error-prone - you could easily fry your Arduino if you connect the wires to the wrong pins). Someone here provided an Arduino sketch which helps you identify the frequency with which the Atmel is running and the comments say 'it is the safest method'. The cloned Arduinos use a lot of different voltage regulators and often you won't even be able to find datasheets for them on Google. If you have a lot of different China-Arduino-clones, the easiest way will be to just test it. Consideration (go down for the actual solution)
