## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect RTC for Raspberry Pi 3B+ Weather Station
*by C***2 on June 27, 2018*

This works perfectly for my solar weather station project. The raspberry uploads sensor data to a database with a timestamp, so accurate timekeeping is a must in the event of a power outage or brownout (solar power issues). This was super easy to install and configure by following the instructions - just google 'RasClock setup'.Also, it does allow to pass through the first six GPIO pins, if you solder on headers to the other side of the board. As long as the other device you're passing through has a different hardware address, it will work. I have the Adafruit BME280 sensor working fine with this setup.

### ⭐⭐⭐⭐ Works well but does not come with a battery - Product description doesn't explicitly state that battery is not included.
*by W***N on August 28, 2016*

Works flawlessly but description on Amazon was misleading (didn't state explicitly that *NO BATTERY INCLUDED". For the price (16.99) a battery was expected. There are other models of RTC modules for have the price that come with batteries or Super-Capacitors.

### ⭐⭐⭐⭐⭐ When you Raspberry Pi project needs the correct time.
*by K***M on September 14, 2016*

WOW! I have a battery backed up clock on my Raspberry Pi now. This thing is working great. It was easy to install and configure. If your Raspberry Pi project needs precise time, this is the clock for you.
