NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Board, 501 Original

NE555 Pulse Frequency Duty Cycle Adjustable Module Square Wave Signal Generator BoardSpecification: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: > = 100MAOutput 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~1kHzHigh frequency file: 1KHz~10kHzHF file: 10kHz~200kHzCycle T = 0.7 (RA + 2RB) C (RA, RB is 0-10K adjustable)Low frequency: C = 100UF; intermediate frequency: C = 1UFM-H frequency: C = 0.1UF; high frequency: C = 0.001UFSize: 30*21*19mm/1.18*0.82*0.74''Note: Please allow 1-3cm differs due to manual measurement.Due to the different display and different light, the picture may not show the actual color of the item.
