240x128 LCD Display Module — Blue/Green Backlight
KY 040 rotary encoder is a device that generates an electrical signal based on how much the rotary input device (knob) is rotated and the direction it is rotating in
AC Tong tester is a good helper to test and troubleshoot faults present in the electrical and electronic system
making it ideal for conditioning slow or noisy input signals into clean digital transitions
TL494CN SOP ESP-01 240x128 LCD Display Module —TL494CN device contains two error amplifiers, an on chip adjustable oscillator, a dead time control (DTC) comparator, a pulse steering control flip flop, a 5 V, 5% precision regulator, and output control circuits. The error amplifiers exhibit a common mode voltage range from 0. 3 V to VCC 2 V. The dead time control comparator has a fixed offset that provides approximately 5% dead time. The on chip oscillator can be bypassed by terminating RT to the
