five digits resolution (display for example x.xxxx kHz, x.xxxx MHz, or xx.xxx MHz) ·

automatic range switching with different gate times ·

optional addition or subtraction of a frequency offset (programmable) ·

very low component count: a PIC 16F628, 5 7-segment LED displays, a 20MHz crystal and a few resistors · optional (configurable)

power-saving mode which automatically turns the display off if the frequency didn't change significantly within 15 seconds
