Description
Description
*FAN / MOTOR CONTROL USING THE NE555 TIMER IC & TIP122*
**Vin** = 12V *
**Vout** = 0-12V
**Max current** =
transistor: 5A
555 IC: 200mA
**Mounting holes**: M3
**BOM Cost **= 1.75USD
*Can be powered from 5V for 5V rated fans. When using 12V fans, it is possible to drive them using a 9V source, but you'll lose 30% of the fan's output range.
