About this item
  • Main chip: N5555;Input voltage: DC5-15V; Output amplitude: 4.2V V-PP(5v input) to 11.4V V-PP(12V input); 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.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
