FTDI Voltage Select The FTDI adapter not only provides a USB port to allow you to communicate with the Pro Mini, it also supplies power. Don't be alarmed at least with my version of the Pro Mini, the red LED simply signifies the unit is powered on, and the blinking red stems from the fact that the unit was pre-programmed with the standard 'blink' sketch - in which the on-board LED blinks once every second.įire up the Arduino IDE, and in the 'tools->boards' menu select the 'Arduino Pro or Pro mini' variant. FTDI adapters come in several shapes and sizes, all of them will have a USB (usually Mini USB) port and a 6-pin connector to attach to the Pro Mini. Now, as you connect the units together via the jumper cables, you may be surprised to note how the Arduino starts blinking red, and furthermore there's a strong red LED that's turned on. Note that the Arduino Pro Mini shouldn't be connected to its' own power source - the FT 232 will deliver the power for now. That's really the only thing that's possible to mess up! The 5v/3.3v setting is made by setting this jumper to its correct position (which should be marked on the board): I was considering the adapter from SparkFun ( SparkFun FTDI Basic Breakout - 5V) but I thought it was rather pricey and in order to switch between 3.3v to 5v you have to solder a connection on the back of the board. Remember to set the FT232 to 5v if you're programming the 5v version of the Pro Mini, and 3.3v if you have the 3.3v Pro mini. I'm fairly new to Arduino and needed something to program an Arduino Pro Mini, which doesn't have a usb connection like the Arduino UNO. So I'm simply using 6 female-to-female jumper cables, not even separated: It's really quite easy, in as much as the pins on the FT232 corresponds exactly to the pins of the Arduino Pro Mini.

Please refer to the below pictures for how to wire the units up. I'm told there's a 5v and a 3.3v version - I got the 5v ones.

The Arduino Pro Mini has the same feature-set as the Arduino Uno, for example, but is much, much smaller and doesn't consume the power the other Arduino's do, so it may be used in battery-powered projects or stuff where space is limited. The FTDI SmartBasic is a variation on our classic FTDI Basic which allows you to connect a second device to the hardware serial port on an Arduino Pro, Pro Mini, or other USB-less board without compromising the ability to bootload code from the Arduino IDE. I've just taken delivery of a couple of Arduino Pro Mini's and want to share how to program them, using the Arduino IDE and a FT232RL FTDI USB to TTL serial adapter.
