Universal 555 flasher/oscillator SMD module

This little module is based on the ever-useful 555 timer IC. It features adjustable frequency over 4 separate ranges and you can also vary the duty cycle. This is ideal for producing timer and clock signals, or for flashing LEDs, or anywhere you would use a 555 timer in astable (oscillator) mode.

Specifications and features:

• Input voltage: 5-15V DC
• Output amplitude: 4.2V - 11.4V (depending on input voltage)
• Input current: ≤15mA (when input 5V) or ≤35mA (when input 12V)
• Output LED indicator onboard
• Selectable output frequency range section, covering the ranges below (values are approx and will vary with module slightly:
