Description

5 pieces mini timer delay module (one-shot timer) for 2-5V power supply. Idle current less than 1 microampere.

After the timer is triggered, its output signal goes LOW for the programmed time. The default output state is HIGH.

The delay can not be re-triggered during the delay time. This can only be done by disconnecting the power supply.

The delay time can be set between 2s and 1000h using just one resistor and 2 internal multipliers.

The jumper P1 (closer to the edge) extends the delay time by factor 8, and jumper P2 (closer to the blob) extends the delay time by factor 64. Closing both jumpers leads to an extension of the delay time by factor 512.

The delay time (in seconds) depends on the resistor value and the supply voltage:
