Main chip: N5555; Input voltage: DC 5V-15V; Input current: ≥ 100MA; Output amplitude: 4.2V V-PPto 11.4V V-PP(Depending on the input voltage, the output amplitude will be different); Output frequency 1Hz-50Hz, 50Hz-1KHz, 1KHz-10KHz, 10KHz-200KHz Four Optional;
There are 4 jumpers and 2 variable resistors on the module, users can adjust the output wave with these components, to get their ideal wave easily.
Output LED indicator,: low-level LED light, high-level LED off, the frequency is low when the LED flashes.
Capacitive capacity determines the frequency range, the user can calculate the adjustment according to their own needs.
The output duty cycle can fine-tune. Duty cycle and frequency is not separately adjustable, adjusting the duty cycle will change the frequency.
