This pin is akin to the VIN pin, or even the barrel jack, on the Arduino Uno. If you have a supply that's greater than 3.3V (but less than 12V), you'll want to connect that to the RAW pin on the Mini. Or you could use a wall power supply along with a barrel jack adapter.
If you want something that matches the compactness of the Pro Mini, a battery - LiPo, alkaline, coin cell, etc. Pick a power source that suits your project. The Pro Mini doesn't have a barrel jack, or any other obvious way to connect a power supply, so how do you power the thing? The most important factor in any project is what's going to power it. That said, don't let the slower speed scare you away from using the Mini 8MHz is still plenty fast, and the Mini will still be capable of controlling almost any project the Arduino Uno can. We put a slower resonator on the Mini to guarantee safe operation of the ATmega. The Pro Mini 3.3V runs at 8MHz, half the speed of an Arduino Uno.
This means that if you've got peripherals that only work at 5V, you might have to do some level shifting before you hook it up to the Pro Mini (or you could go for the 5V variant of the Pro Mini).Īnother major variation from the standard Arduino lies in the speed at which the ATmega328 runs. Unlike the Arduino Uno, which has both a 5V and 3.3V regulator on board, the Mini only has one regulator. The first glaring hardware difference is the voltage that the Mini operates at: 3.3V. The Mini packs almost as much microprocessor-punch as the regular Arduino, but there are a few major hardware changes you should be aware of before you start adapting your project to the Mini. Of course, if you are not happy with your order you can return it back to us for any reason within 14 days of receiving it.Comparing the size of a standard Arduino Uno with the (aptly named) Pro Mini. We have now sold hundreds of Arduino boards and have an almost insignificant return rate. All our Arduino boards are built and tested at the same factory. The only significant difference is the price.
#USING ARDUINO PRO MINI SOFTWARE#
It also contains the same boot loader and is therefore identical in design, build and software to an original board. Arduino is an open standard and this board has been built exactly to the Arduino open source reference design. Please note that this item is Arduino compatible. This product is manufactured by Deek-Robot and is derived from the SparkFun(TM) Pro Mini reference design which was released under the Creative commons Attribution-ShareAlike 3.0 licence. This version of the Pro Mini runs at 5V and 16 MHz. The pin layout is compatible with the Arduino Mini. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The Arduino Pro Mini is intended for semi-permanent installation in objects or exhibitions. A six pin header can be connected to an FTDI cable to provide USB power and communication to the board. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. The Arduino Pro Mini is a microcontroller board based on the ATmega 328.
