Product Change Notification in V1.5:
1. Have moved the two buttons to the backside;
2. Have add the socket female pins on the PCB, which you can replace the tube by hand;
3. Update the RTC to DTCXO (temperature compensated crystal oscillator) version, High Stability, Highly accurate.
It has ±1.9ppm (Equivalent to ±4.94s seconds of month deviation) under 0ºC~+40ºC. Usually you don't need to set the time for over a year.
