About this item

  • NE555 timer: NE555 timer is an integrated circuit chip, which is often used in timers, pulse generators and oscillator circuits. The 555 can be used as a delay device, trigger or start-up element in the circuit. 555 timer can work in three working modes: monostable mode, astable mode, bistable mode.
  • Product introduction: Onboard NE555 chip, working voltage: 5~12V, output current 225 mA (MAX), rise/fall time 100 ns.
  • Features: Single-channel signal output, the output duty cycle is about 50% of the waveform, the potentiometer adjusts the output frequency, the output frequency range is 5~2KHZ (changing the capacitor C1 can change the output frequency), the output voltage is equal to the input voltage.
  • Application: Computer stepper motor stepper generation, etc. Applicable occasions: single-chip learning, electronic competition, product development, taxi meter, graduation design.
  • Package includes: You will get 5 x NE555 Pulse Generator Module, 1 x 15pin Female to Male Dupont Cable.

Hey I'm trying to power this with a 9-volt battery which should work according to a little information I can find. But it gets very hot and the frequency is completely unstable. Is there something I am missing? Is there too much amperage coming out of of 9 volt battery? I've seen lots of any 555 homebrewed frequency circuits that just used a straight 9 volt battery. Not enough information on your site to get this to work right.

No LED. Schematic on website suggested it has more features than physically present on the board. The freqency range did not adjust below a few kilohertz, as provided. It was more like 2-5khz and not 5-2khz, as stated.

Simplemente funciona. Los potenciómetros multivuelta hacen que sea muy fácil afinar la frecuencia de salida.
