To be installed in computers

Real time clock

Built in, capable of running 100h after a power failure (precondition: the basic module has worked for at least 2 minutes before the power failure)

[1]: The analog potentiometer provides users an method for setting inner element, which is within 0~255 and read by user program. To adjust the setting, you can use a small Philips screwdriver to rotate the potentiometer clockwise to raise the setting. The maximum rotation angle is 270°.

[2]: Provide register forced function, convenient for debugging and analyzing the user program, improving debugging efficiency. Supportive of forcing 128 bit-registers and 16 word-registers at the same time.

[3]: supportive of online user program modification
