I'm quite satisfied with my product , my only downside is that the big MOSFET and parts next it heat up under load ,but product quality is good
2A Dual L298N Motor Driver Module with PWM Control
Quad NOR R-S Latch Tri-state IC - CD4043
Let us know!
We'll try to match the price for you
Couldn't load pickup availability
The CD4x Series CD4043 IC is quad cross-coupled 3-STATE CMOS NOR latches These latch has a separate Q output and individual SET and RESET inputs. There is a common 3-STATE ENABLE input for all four latches.
A logic “1” on the ENABLE input connects the latch states to the Q outputs. A logic “0” on the ENABLE input disconnects the latch states from the Q outputs resulting in an open circuit condition on the Q output. The 3-STATE feature allows common bussing of the outputs.
