The range of the internal clock oscillator is about 100Hz ... 100kHz. But if you use an external clock it can be as slow as you
want.

You may also modify the internal oscillator by increasing the value of the frequency capacitor of the oscillator. That's C1 at the
top edge of the pcb. The factory value is 10nF. If you solder e.g. 100nF in parallel to C1 the frequency range is divided by 10
(10Hz ... 10kHz), if 1uF is used the frequency range is divided by 100 (1Hz ... 1kHz) and so on.

Another random clock source is the A-149-2.
