Efficient and Game-Changing!

As a user that frequently upgrades components, I am always looking for something that can make my computer run more efficiently. As a result of using this product, I found that the battery life of my Raspberry Pi is significantly better and runs at a more consistent rate. The only drawback I found is that it takes a bit of extra effort to install properly, but the end result is well worth it. Highly recommended for anyone looking for a game-changing addition to their computer components.

Pros
  • Long lasting battery life for the Raspberry Pi
Cons
  • Not compatible with other microcontrollers

Works as advertised

I bought this for a RISC-V FPGA project, but I installed additional components in my Raspberry Pi. They connect directly to the GPIO header. After a few minutes of research online, I received instructions to replace the fake RTCs with real ones. Great value for money.

Pros
  • Quality Assurance
Cons
  • Makes me angry

Received a mixed M and SN version of the RTC chip

I received 4 RTC modules, two with the more accurate SN version of the DS3231 chip as shown in their pictures and 2 were the M Version with lower precision chip. As far as I remember the description doesn't specify the type but the photos show the SN model so I thought I was sure. not so. I returned 4 RTCs and bought the same RTCs from another seller (different Amazon product display but identical product) and received 4 RTCs with SN chip. Another thing to check is the battery voltage as I…

Pros
  • Full features
Cons
  • Clarity
