NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator Board
Specification:
Input voltage: 5V-15VDC. When the power supply is 5V, the output current can be about 15MA, and when the power supply is 12V, the output current can be about 35MA.
Input current: > = 100MA
Output range: 4.2V V-PP to 11.4V V-PP. (the input voltage is different, the output amplitude is also different).
Maximum output current: >= 15MA (5V power supply, V-PP > 50%), > =35MA (12V power supply, V-PP > 50%)
With LED indicator output (low level, LED light; high level, LED extinction; low frequency, LED flicker)
The output frequency range is optional.
LF file: 1Hz~50Hz IF file: 50Hz~1kHz
High frequency file: 1KHz~10kHz
HF file: 10kHz~200kHz
Cycle T = 0.7 (RA + 2RB) C (RA, RB is 0-10K adjustable)
Low frequency: C = 100UF; intermediate frequency: C = 1UF
M-H frequency: C = 0.1UF; high frequency: C = 0.001UF
Size: 30*21*19mm/1.18*0.82*0.74''
