I built a volt/amp meter with an arduino nano and a little .9 inch screen. I have done any calibration or fact checking on the accuracy of it, but it does seem to work with that library. I started my build with the dronebot workshop (youtube videos that are GREAT) explanation of this ina219 sensor and then modified based on some other youtube builders. --- ## 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.gr/products/149690768-hiletgo-2pcs-ina219-i2c-bi-directional-dc-current-power-supply](https://www.desertcart.gr/products/149690768-hiletgo-2pcs-ina219-i2c-bi-directional-dc-current-power-supply) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-31*
