Ideal for professionals seeking a reliable, high-performance microcontroller platform in a minimalist form factor. ## Description Since 2003, SparkFun has been helping turn ideas into reality. We're here to help you . It's blue! It's thin! It's the Arduino Pro Mini! This is a 5V Arduino running the 16MHz bootloader. This Pro Mini had male headers soldered into all pins, so it could slot directly into a breadboard. Notice the programming header pins are soldered "upside-down", to keep them accessible. Programming the Pro Mini. The Pro Mini included in the assembly of a project. The Pro Mini's pins surround three of the four sides. The pins on the short side are used for programming, they match up to the FTDI Basic Breakout. The pins on the other two sides are an assortment of power and GPIO pins (just like the standard Arduino). There are three different power-related pins: GND, VCC, and RAW. GND, obviously, is the common/ground/0V reference. RAW is the input voltage that runs into the regulator. The voltage at this input can be anywhere from 3.4 to 12V. The voltage at VCC is supplied directly to the Pro Mini, so any voltage applied to that pin should already be regulated to 3.3V. Four pins are actually not located on the edge of the board: A4, A5, A6 and A7. Each of these analog pins is labeled on the back side of the board. 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. The first glaring hardware difference is the voltage that the Mini operates at: . Unlike the Arduino Uno, which has both a 5V and 3.3V regulator on board, the Mini only has one regulator. 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). Another major variation from the standard Arduino lies in the speed at which the ATmega328 runs. The Pro Mini 3.3V runs at , half the speed of an Arduino Uno. We put a slower resonator on the Mini to ensure safe operation of the ATmega. 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. ## Features - ATmega328 running at 16MHz with external resonator (0.5% tolerance) - No USB connection off board. Need FTDI board (or similar device) to program. - Supports auto-reset - 5V regulator - Max 150mA output ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B004G53J5I | | Best Sellers Rank | #2,731 in Single Board Computers (Computers & Accessories) | | Brand | SparkFun | | Color | Blue | | Customer Reviews | 4.4 4.4 out of 5 stars (79) 4.4 out of 5 stars | | Date First Available | December 13, 2010 | | Item Dimensions Lxwxh | 1.3 x 0.71 x 0.03 inches | | Item Model Number | Pro Mini 5V/16MHz | | Item Weight | 0.176 ounces | | Manufacturer | SparkFun Electronics | | Number Of Processors | 1 | | Operating System | FreeRTOS | | Processor Brand | Atmel | | Product Dimensions | 1.3 x 0.71 x 0.03 inches | | Ram | SRAM | | Series | Pro Mini | ## Product Details - **Brand:** SparkFun - **Model Name:** Pro Mini - **Connectivity Technology:** I2C, SPI - **Operating System:** FreeRTOS - **CPU Manufacturer:** Atmel ## Images ![Pro Mini ATmega328-5V/16MHz Development Board - Image 1](https://m.media-amazon.com/images/I/71ijJN9ToFL.jpg) ![Pro Mini ATmega328-5V/16MHz Development Board - Image 2](https://m.media-amazon.com/images/I/81O34H+31gL.jpg) ![Pro Mini ATmega328-5V/16MHz Development Board - Image 3](https://m.media-amazon.com/images/I/7190agjd+gL.jpg) ![Pro Mini ATmega328-5V/16MHz Development Board - Image 4](https://m.media-amazon.com/images/I/71l4ZdqUIAL.jpg) ![Pro Mini ATmega328-5V/16MHz Development Board - Image 5](https://m.media-amazon.com/images/I/41fH+C3apQL.jpg) ## Questions & Answers **Q: This board will able to connect led light and sound?** A: It can be used the same as any Arduino, it just has fewer inputs and outputs. It also needs any headers you want to use soldered on. **Q: Where can I get a schematic for this board?** A: Sparkfun, https://www.sparkfun.com/products/11113 **Q: 150mA output? I see that these have a max output of 150ma- is that total? Digital? Analog? I am looking to run 27 charlieplexed LEDs in open heart** A: 150 mA is the limit for the onboard voltage regulator. The Pro Mini should have no trouble driving 27 Charliplexed LEDs directly because it's only turning on a few LEDs at time. **Q: Does this board include the 3 pin headers for programming and breadboard mounting?** A: This board does not include any headers. Many of our customers already have headers or prefer to choose what they want to put on the board. ## Frequently Bought Together - SparkFun Pro Mini ATmega328-5V/16MHz Development Board Compatible with Arduino Boards and IDE - Bridgold 10pcs AMS1117-3.3 AMS1117-3.3V 1117 Forward Low Voltage Linear Regulator 3.3V 1A for Laptop Mobile Phone Battery Charger. - WMYCONGCONG 10 PCS Game Joystick Breakout Module Game Controller Replacement Joystick Control Stick Compatible with PS2 Switch Joy-Con Controller --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.mx/products/1921105-pro-mini-atmega328-5v-16mhz-development-board](https://www.desertcart.mx/products/1921105-pro-mini-atmega328-5v-16mhz-development-board) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-09-30*
