It comes with NO documentation. P1 is the i2c connection for the device, P2 is a pass through connection to the next i2c device in the chain. Since the board is for Arduino and I wanted to use it for Raspberry Pi I needed to destroy the two resistors at the base of the board to keep the voltage logic at 3V rather than 5V (I think they are R1 and R2 - near the bottom edge)http://www.hobbyist.co.nz/?q=real_time_clock ### ⭐ I tested this RTC with several different connectors, libraries ... *by O***S on Reviewed in the United States on May 12, 2015* I tested this RTC with several different connectors, libraries and batteries - it doesn't work. When tested via I2c, serial port returns "communication error." It will display an arbitrary time, but the time can't be set. JUNK! ### ⭐⭐⭐⭐ Four Stars *by A***W on Reviewed in the United States on February 6, 2017* only bad thing i can say is i wish it came with the battery --- ## 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.nz/products/12852104-tiny-rtc-i2c-module-24c32-memory-ds1307-clock-high-precision](https://www.desertcart.nz/products/12852104-tiny-rtc-i2c-module-24c32-memory-ds1307-clock-high-precision) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-05-17*
