Description:
1. Onboard NE555 IC.
2. Single channel signal output, the output duty cycle about 50% square wave.
3. Plate load resistor, adjust the resistance to control the output frequency.
4. Onboard power indicator.
5. Working voltage: 5V~12V.
6. Size: 3*1.5cm

Note:
1. Different displays and light sources may cause color deviation
2. The size is manually measured, there is an error of 1~5mm
