No issues. I use them for miniture remote weather stations. Instructions are clear enough and sketches are available, but not from me. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Fits and work *by J***Y on Reviewed in the United States on March 21, 2024* four out of four work as expected.I am very please with the purchase.Will definitely buy again. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great value! *by C***N on Reviewed in the United States on March 3, 2021* I wish I could give more than 5 stars on “value for money” I never realized how much cheaper it is if you spend an extra 5 minutes to solder the board yourself! You don’t have to be an expert to solder it either, it’s very simple, very basic, quick, and easy! The screens work great, once dialed in with the small screw on the back, they work great and are very responsive to changes. --- ## 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.cy/products/260681602-weewooday-4set-iic-twi-i2c-lcd-serial-interface-adapter-liquid](https://www.desertcart.com.cy/products/260681602-weewooday-4set-iic-twi-i2c-lcd-serial-interface-adapter-liquid) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-30*
