Its stackable design and stable SPI communication make it ideal for professional-grade data logging and custom electronics projects, empowering makers and managers alike to capture and analyze data with precision and ease. ## 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.

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 on Reviewed in the United States August 3, 2022* This HiLetgo module is an inexpensive option for logging data on UNOs and compatibles. 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! ### ⭐⭐⭐⭐⭐ works *by on Reviewed in the United States January 21, 2021* 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. ### ⭐⭐⭐⭐ Shield works great on the Arduino R3, Not the MEGA 2560 R3 *by on Reviewed in the United States September 14, 2015* This shield came on time and was exactly as described.This is an R3 version shield, but since it doesn't have an ICSP jack, it won't work interchangeably with the MEGA 2560 R3, without modifying things. Also, this card uses Pin 10 for SD, not the default pin 4 that the Arduino SD library defaults too. Once that's changed, the SD card functions with the library.A minus: because this version of the shield does not have an ICSP jack and pins incorporated, it will be hard to use it on the Mega 2560. They are other shields that do, but none incorporate the RTC, that I am aware of. I realize this is exactly what the open-source has, so I don't fault the shield manufacturers.A plus is the clock. It works well. The SD library doesn't support writing a date (from the RTC) automatically. You need to add a clock call-back function to the loop(), and associate it correctly, during setup. Once that's done, it works very well.Another plus is that it is R3 compatible, so it includes the SDA and SCL pins. They are also broken out so they are easy to use. I find it a useful shield and have incorporated it into an automatic SD temperature logging sensor project. It functions very well and with the clock helped me to reduce the number of shields/additional components.I would use it again, assuming it will be used on the Arduino UNO R3.Note: To repeat, I don't blame the manufacture for the negative things, this is exactly what the open-source specified and they have followed it. ## 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? - 🛒 **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.com.sa/products/14948684-hiletgo-data-logger-module-logging-shield-data-recorder-shield-arduino](https://www.desertcart.com.sa/products/14948684-hiletgo-data-logger-module-logging-shield-data-recorder-shield-arduino) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-09-13*
