It supports microSD cards up to 64GB with FAT16/32 formatting and configurable baud rates up to 115200bps, making it ideal for extensive data logging and debugging. Designed for easy integration with Arduino platforms, it features low power consumption and a simple serial interface, enabling professionals to effortlessly archive large volumes of project data. ## Description The SparkFun OpenLog is an open source data logger that works over a simple serial connection and supports microSD cards up to 64GB. The OpenLog can store or log huge amounts of serial data and act as a black box of sorts to store all the serial data that your project generates, for scientific or debugging purposes.The SparkFun OpenLog runs off of an onboard ATmega328, running at 16MHz thanks to the onboard crystal.The ATmega328 has the Optiboot bootloader loaded on it, which allows the OpenLog to be compatible with the "Arduino Uno" board setting in the Arduino IDE.The OpenLog draws 6mA when recording a 512 byte buffer, but as that process takes a fraction of a second, the average current draw is closer to 5mA. Keep in mind though that if you are recording a constant data stream at 115200bps, you will approach that 6mA limit.All data logged by the OpenLog is stored on the microSD card that involve the features of 64MB to 64GB capacity and FAT16 or FAT32 file type.The primary interface with the OpenLog is the FTDI header on the board edge. This header is designed to plug directly into an Arduino Pro or Pro Mini, which allows the microcontroller to send the data over a serial connection to the OpenLog. ## Features - VCC Input: 3.3V-12V (Recommended 3.3V-5V); Configurable baud rates (up to 115200bps) - Log to microSD FAT16/32 cards up to 32GB: Store huge amounts of data from your project - Preprogrammed ATmega328 and bootloader: Simple command interface - Four SPI pogo pins: For a simple connection to your project; Two LEDs: indicate writing status - Two recording speeds: 2mA idle when nothing to record;, 6mA at maximum recording rate ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079LPZ4YD | | Best Sellers Rank | #5,021 in Single Board Computers (Computers & Accessories) | | Brand | SparkFun | | Compatible Devices | Personal Computer, Laptop, Smartphone, Tablet | | Customer Reviews | 3.8 out of 5 stars 19 Reviews | | Digital Recording Time | 149 hours | | Format | Unknown format | | Hardware Interface | MicroSD | | Headphones Jack | No headphones jack | | Item Weight | 0.01 Kilograms | | Manufacturer | SparkFun Electronics | | Memory Storage Capacity | 64 GB | | Mfr Part Number | DEV-13712 | | Microphone Form Factor | Built-In | | Microphone Operation Mode | Mono | | Model Number | SparkFun OpenLog | | UPC | 845156006540 | | Unit Count | 1.0 Count | | Warranty Description | 30 Day | ## Product Details - **Brand:** SparkFun - **Compatible Devices:** Personal Computer, Laptop, Smartphone, Tablet - **Digital Recording Time:** 149 hours - **Format:** Unknown format - **Hardware Interface:** MicroSD - **Headphones Jack:** No headphones jack - **Item Weight:** 0.01 Kilograms - **Memory Storage Capacity:** 64 GB - **Microphone Form Factor:** Built-In - **Microphone Operation Mode:** Mono ## Images ![SparkFun OpenLog Open - Image 1](https://m.media-amazon.com/images/I/61VMo1BlyKL.jpg) ![SparkFun OpenLog Open - Image 2](https://m.media-amazon.com/images/I/71OujgyYjVL.jpg) ![SparkFun OpenLog Open - Image 3](https://m.media-amazon.com/images/I/61molWoi6DL.jpg) ![SparkFun OpenLog Open - Image 4](https://m.media-amazon.com/images/I/51CHIDabK5L.jpg) ![SparkFun OpenLog Open - Image 5](https://m.media-amazon.com/images/I/51nLWeM7zrL.jpg) ## Frequently Bought Together - SparkFun OpenLog Open-source data logger works over a simple serial connection Supports microSD FAT16/32 cards up to 32GB Configurable baud rates up to 115200bps Preprogrammed ATmega328 and bootloader - Lexar 32GB Micro SD Card 3 Pack, microSDHC UHS-I Flash Memory Card with Adapter - Up to 100MB/s, U1, Class10, V10, A1, High Speed TF Card (3 microSD Cards + 1 Adapter) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/145534095-sparkfun-openlog-open](https://www.desertcart.uy/products/145534095-sparkfun-openlog-open) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-08-26*
