DC 5V NE555 Adjustable Pulse Generator Module adjustable Frequency Duty Cycle Square Wave Signal Generator with LED Indicator
Description:
Size: 20mm * 40mm
2. Function: generate square waves or square waves of different frequencies;
Parameter index:
(1) Power supply: Input voltage: 5V. 5V power supply, the output current can be around 10MA;
(2) Frequency: 5 bands (discovered)
J1 file: 0.6Hz~25Hz
J2 file: 7Hz~300Hz
J3 file: 50Hz~2.5kHz
J4 block: 350kHz~6.6kHz
J5 block: 6.7kHz~180kHz
Adjustable duty cycle range: 0.4-0.99
(3) LED output indicator, low-level LED light, LED off high, LED flashing speed represents output frequency change; in addition to selecting different frequency bands outside the jumper cap, RV1 adjustment can adjust the frequency, the adjustment can see the flashing LED adjustment corresponding Frequency change;
(4) Input current: ≥100MA
(5) Output voltage: 4.2V
(6) Output frequency calculation: period T = 0.7 (Ra + 2Rb) C Ra, Rb is adjustable from 0 to 10K;
(7) Input: VCC GND Output: VCC OUT GND Input Voltage and Output Consistency Here, user-friendly purposes can follow up the power supply. OUT is the output frequency signal.
