Review: Great little clock kit but requires USB power supply - Even though this basic clock kit came with no instructions it was easy to install and solder the components using the markings on the printed circuit board. As mentioned in other reviews it is important to connect the solder points for J1 and J2 with wire before attaching the display. When I first connected the battery pack, the clock worked for about 24 hours before the display stopped functioning properly. It appears that over a short period of time the battery voltage drops and cannot power all 4 digits. I replaced the battery with a 5v USB cable and the unit now works fine. If the kit had come with a USB connector, I would have given it a 5 star rating. ## Features - This practical practice board is easy to assemble and soldering, exactly suitable for the electronic learner and school teaching. - Accurate travel time, don't worry about the time being inaccurate. - These practice learning kits have high performance-price, suitable for bulk purchase of school and educational institution. - Supply voltage: 3V ~ 6V, PCB Size: 50mm x 19mm. - Please make sure all components in right direction and right place; and check whether pseudo and float welding, this is very important in practicing and testing. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07GZLBPHV | | Assembly required | Yes | | Brand | Gikfun | | Brand Name | Gikfun | | Customer Reviews | 4.0 out of 5 stars 58 Reviews | | Is Assembly Required | Yes | | Item Dimensions | 50 x 19 x 190 millimeters | | Item Weight | 0.02 Kilograms | | Item dimensions L x W x H | 50 x 19 x 190 millimeters | | Item weight | 0.02 Kilograms | | Manufacturer | Esooho | | Manufacturer Minimum Age (MONTHS) | 6.00 | | Manufacturer Part Number | EK1939 | | Material Type | FR4 | | Model Number | EK1939 | | Theme | Number | ## Images ![Gikfun C51 4 Bits Digital LED Electronic Soldering Clock Kits Electronic Practice Learning Board DIY Kit for Arduino EK1939 - Image 1](https://m.media-amazon.com/images/I/71QKzskXU7L.jpg) ![Gikfun C51 4 Bits Digital LED Electronic Soldering Clock Kits Electronic Practice Learning Board DIY Kit for Arduino EK1939 - Image 2](https://m.media-amazon.com/images/I/61FMx0+YGKL.jpg) ![Gikfun C51 4 Bits Digital LED Electronic Soldering Clock Kits Electronic Practice Learning Board DIY Kit for Arduino EK1939 - Image 3](https://m.media-amazon.com/images/I/61S4JzyxsEL.jpg) ![Gikfun C51 4 Bits Digital LED Electronic Soldering Clock Kits Electronic Practice Learning Board DIY Kit for Arduino EK1939 - Image 4](https://m.media-amazon.com/images/I/71B6+kF7dtL.jpg) ![Gikfun C51 4 Bits Digital LED Electronic Soldering Clock Kits Electronic Practice Learning Board DIY Kit for Arduino EK1939 - Image 5](https://m.media-amazon.com/images/I/61gUZjD1+UL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great - Love it *by T***. on 18 March 2023* Not bad - took a little time and patience to assemble but works as expected and keeps time! ### ⭐⭐⭐⭐ Great little clock kit but requires USB power supply *by B***. on 10 January 2021* Even though this basic clock kit came with no instructions it was easy to install and solder the components using the markings on the printed circuit board.

It’s been incredibly frustrating for the first-time solderer I bought it for: Every time he touches it, a circuit trace tears loose and it stops working. With the other problems like incomplete instructions and a weak defective battery holder, I seriously don’t recommend this for anyone, ESPECIALLY not a beginner. ## Frequently Bought Together - Gikfun C51 4 Bits Digital LED Electronic Soldering Clock Kits Electronic Practice Learning Board DIY Kit for Arduino EK1939 - Gikfun DIY SMD SMT Welding Practice Soldering Skill Training Board NE555 CD4017 Water Flowing Led DIY Kit EK1885 - Thermaltronics TMT-TC-2 Tip Tinner (20g) in 0.8oz Container --- ## 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.ma/products/320168832-gikfun-c51-4-bits-digital-led-electronic-soldering-clock-kits](https://www.desertcart.ma/products/320168832-gikfun-c51-4-bits-digital-led-electronic-soldering-clock-kits) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-06-14*
