I figure at some point the seller added a link to the instructions on this page, so there you go. I've been using this board and it works fine, just as advertised. If you have zero experienced with Arduino, I suggest you watch some tutorials and try some simple projects like the LED blink before you try to assemble something more complex like this kit.I must say the OLED display is very nice, super sharp and amazing contrast. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars It's great. Instructions are posted on store page. Authentic Parts. *by F***O on Reviewed in the United States on July 30, 2020* I learned more from this than anything else I've ever done with Arduino... How to use a real time module, how to user an OLED screen, how to communicate with (such as the aforementioned) over serial connections, SPI/I2C, plus it's my first nano board. Mine even came with an SD-card breakout board not used in the tutorial, now I can play around with that too, as well as a couple of extra buttons, lots of extra dupont wires.The code in the instructions is a great starting point for tinkering. I changed the date format and switched the temperature to display in Fahrenheit instead of Celsius. Next, I'll put a few of those buttons to use and make it more user friendly to set the time... Perhaps add a calibration offset for the temperature. Etc etc.NOTE:The instructions are right here on the store page under "Technical Specifications", attached as a .pdf file. Download the .pdf, take a look, and if it looks like fun I say go for it! ### ⭐⭐ 2.0 out of 5 stars Unfortunately not a good experience *by D***E on Reviewed in the United States on October 30, 2020* I did assemble and get this kit working and did enjoy making some modifications to the software to reformat the text display to be bigger for my old eyes. However, there was no battery included in the kit as stated. After contacting the seller they did issue a credit of an amount almost sufficient to pay for one...and they did it quickly (given time difference to working hours in Shenzhen). Also note the documentation says to use an A123 battery which will obviously not fit here. This uses a CR2032 battery. As per other reviews, the parts did not really fit on the breadboard that was included so I had to realign to get it to fit and that was successful. Unfortunately, however, the breadboard was slightly warped and, therefore, it was very, very hard to get the nano into the sockets and even the wiring was difficult to insert into the board. I had to use a needle-nose pliers to get them in. Eventually I did that. The buzzer is very, very weak and almost sounds like a cat in distress (although at low volume). I removed the code for the buzzer as it was too annoying. The worst part of the project, however, was the OLED failed after a couple of days. I had another kit with a different brand OLED and swapped them out and it was clear the part from this kit was at fault. It did not work in this setup or in the other whereas the one I had from the another vendor worked fine in both places. That was strike three for me. I think the quality of the parts they were using was poor. Not too surprising, actually, for these things but I had great hopes that once assembled into a difficult breadboard, eliminating the buzzer and ordering a battery, I would be done. But when the display fails all you really have is a bunch of spare parts. Thanks to Amazon fulfillment services, however, I was able to get a refund so I can try again, albiet probably not getting anything from this vendor, sadly. --- ## 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.br/products/180710814-wayintop-real-time-clock-kit-with-tutorial-for-arduino-ds3231](https://www.desertcart.com.br/products/180710814-wayintop-real-time-clock-kit-with-tutorial-for-arduino-ds3231) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-05-18*
