Good real time clock, be aware it's the "M" version
6 of 6 found this helpful Can't beat this RTC for the price. Be aware that this one ships with the DS3231M version of the chip, which works fine for time but does NOT allow you to set the square wave output pin to anything other than 1 Hz. If you need the pin to produce another frequency (I needed 1024 Hz) you need to look for a DS3231N version. Still a very good price for a solid RTC.

These are great little VFD units
These work well. If you are using Arduino, the standard 2x16 LiquidCrystal library will work. 5 volts is all you need, just pay attention to the pins because they are slightly different to an actual LCD.

TCCM was exactly what I needed
Fixed the problem with 4WD, so thumbs up!
