Description
The NE555 Pulse Module is a signal generator that can produce square wave and rectangular wave signals with adjustable frequency and duty cycle. It has a working voltage of DC5-15V and an input current of =100mA. The output range is 4.2V V-PP to 11.4V V-PP, with an output current of 5V power supply V-PP greater than 50%, = 15mA and 12V power supply V-PP greater than 50%, = 35mA. The output frequency can be set to 1Hz-50Hz, 50Hz-1KHz, 1KHz-10KHz, or 10KHz-200KHz. The PCB size is 37 * 33mm and it weighs 10g. The product features an output LED indicator and adjustable duty cycle and frequency. The package includes 1 NE555 Pulse Module.

Features:
1. Output LED indicator,: low-level LED light, high-level LED off, the frequency is low when the LED flashes.
2. Output frequency range optional, the output frequency, duty cycle continuously adjustable:
Low frequency: 1Hz-50Hz,
Medium frequency: 50Hz-1KHz,
Medium - high frequency: 1KHz-10KHz,
High frequency: 10KHz-200KHz;
On the control panel precision adjustable resistance VR1 is to adjust the duty cycle, VR2 to adjust the frequency;
3. Output frequency range adjustable:
Period T = 0.7 (RA + 2RB) C; VR1 on the board, VR2 is 0-10K precision adjustable resistance;
Low frequency C = 102 (0.001UF);
Medium frequency C = 104 (0.1UF);
Medium - high frequency: C = 105 (1UF);
High frequency: C = 100UF.
Capacitive capacity determines the frequency range, the user can calculate the adjustment according to their own needs.
