Featuring a 3.3V level shifter to protect your SD card and an onboard prototyping area, it’s perfect for professionals seeking efficient, customizable data logging solutions with quick-start libraries included. ## Description Features: Onboard 3.3V regulator is both a reliable reference voltage and also reliably runs SD cards that require a lot of power to run. Works with Arduino UNO, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher. ADK/Mega R2 or lower are not supported. Specification: Size: 68 x 53 x 23mm (approx) Regulator voltage: 3.3V Note: This project does not come with an Arduino (you need to use a shield), or an SD card. All the components of the geothermal fire are soldered and tested, but no head mounted. You need some basic soldering skills to put it together, but even if you do not have much experience you can get it done in 15 minutes.The SDA/SCL pins (next to the reset button) are not connected. If you use a board other than R3, you need to connect the A4/A5 pins to proper SDA/SCL pins manually.

It requires a CR1220 coin cell battery, not included, to store date and time when not under power. The real time clock (RTC) requires a software library, but these libraries are widely available online and can be installed from any recent version of the Arduino Integrated Development Environment (IDE). The software library for the SD card is part of an IDE installation. There might be concerns about quality control at this low price, but I have used many of these modules without problems. The RTC will gain or lose time slowly over weeks or months (depending on temperature), but this is a property of the clock oscillator and not this particular device. In conclusion... highly recommended if you need data logging with UNOs! Review: works - I bought this for the rtc on a shield. Might use sd logging at some point. I don't like that I had to connect sda to a4 and sdl to a5 myself. I used superglue to attach a wires. The whole point of a shield is to get rid of some of the wire mess. In any case works well. The day of the week did not work for me, but I did not need it. I used this to turn an arduino and a doorbell into a kind of grandfather clock. ## Features - SD card interface works with FAT16 or FAT32 formatted cards. - 3.3V level shifter circuitry prevents damage to your SD card. - Real time clock (RTC) keeps the time going even when the Arduino is unplugged. - Included libraries and example code for both SD and RTC, means you can get going quickly. - Prototyping area for soldering connectors, circuitry or sensors. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00PI6TQWO | | Best Sellers Rank | #58,787 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #10 in Industrial Data Loggers | | Date First Available | November 12, 2014 | | Department | unisex-adult | | Is Discontinued By Manufacturer | No | | Item Weight | 1.13 ounces | | Item model number | 3-01-1038-1 | | Manufacturer | HiLetgo | | Package Dimensions | 4.72 x 3.23 x 1.34 inches | ## Images ![Data Logger Module Logging Shield Data Recorder Shield for Arduino UNO w/SD Card - Image 1](https://m.media-amazon.com/images/I/61A8iYOE2JL.jpg) ## Questions & Answers **Q: I need to log data from 6 sensors. Is there a hardware limit on the number of channels, or is this programmable?** A: The Arduino Uno R3 has 6 analog inputs the can convert a voltage signal into a binary number the the microcontroller can make use of. You also have 14 digital IO pins that can be used to determine if a switch is on or off. The Uno can also receive digital data from a large number of sensors using I2C, OneWire and SPI protocols. So the number of sensors could approach 100 and should be writable to the SD card. **Q: Mine did not come with a battery. What battery does it use?** A: Lithium cell CR1220 3V with the + showing. **Q: Does it work with a Mega 2560 ?** A: yes, I use it with 2560, plugs into the 2560 **Q: Does it come with the headers pictured? (able to continue stacking)** A: It is stackable ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable data logger for UNOs and compatibles. *by I***E on August 3, 2022* This HiLetgo module is an inexpensive option for logging data on UNOs and compatibles.

I don't like that I had to connect sda to a4 and sdl to a5 myself. I used superglue to attach a wires. The whole point of a shield is to get rid of some of the wire mess. In any case works well. The day of the week did not work for me, but I did not need it. I used this to turn an arduino and a doorbell into a kind of grandfather clock. ### ⭐⭐⭐⭐ Very simple hardware... works great! *by J***N on September 5, 2018* Nice shield. Excellent value! It is very simple -- has a DS1307 RTC, an SD card reader, and a small vector board area for soldering in custom sensors. RTC does not come connected -- you must connect the SCL and SDA pins then use the library "RTClib" available on github. Recommended not for beginners unless you're willing to learn how to use I2C communications. Not 5 stars because the pins are somewhat flimsy and there was no documentation included though I will likely buy a couple more at this price. ## Frequently Bought Together - HiLetgo Data Logger Module Logging Shield Data Recorder Shield for Arduino UNO w/SD Card - Arduino UNO R4 WiFi [ABX00087] - Renesas RA4M1 / ESP32-S3 - Wi-Fi, Bluetooth, USB-C, CAN, DAC, OP AMP, Qwiic Connector, 12x8 LED Matrix - Arduino Uno REV3 [A000066] --- ## 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.kr/products/14948684-data-logger-module-logging-shield-data-recorder-shield-for-arduino](https://www.desertcart.kr/products/14948684-data-logger-module-logging-shield-data-recorder-shield-for-arduino) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-27*
