The Arduino Pro Mini is SparkFun’s minimal design approach to Arduino. It’s essentially a 3.3v Arduino that runs an 8 MHz bootloader on a super small, super thin board. There are no connectors attached – allowing you to add whatever connectors or wire you want without too much trouble.
The goal of the Pro Mini isn’t to replace the Arduino so much as bring the cost down for more advanced users. The Arduino Uno is still the inimitable board but if you’re comfortable working within voltage limitations, don’t mind off-board USB, and want to customize your connectors, the Arduino Pro Mini’s a great budget purchase. You will need an FTDI friend or FTDI cable to program your Pro Mini, and we also recommend some plain header to solder it for breadboard use.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
This is a nice design. Has two more analog inputs than a standard Arduino. I’m building a memory keyer using one.
