Breadboard-only schematic for an ESP32-based LC electromagnetic response visualizer using a handmade coil oscillator, LM339 comparator, GPIO27 frequency input, SSD1306 I2C OLED, and calibration button. No PCB layout is included.

Controlador PID analógico para motor DC con salida PWM aislada mediante PC817, basado en op-amps cuádruples, LM311 y oscilador triangular de ~10 kHz

This is an LMZ31503RUQR power convector module with an input voltage of 4.5-14V and an output voltage of 3.3V. The output power of the module is 9.9W #DCDC #3V3 #power #9W #14V #5V #4V5 #referenceDesign #powermanagement #texas-instruments #template #reference-design

This project is a voltage comparator circuit utilizing an LM311DR comparator and an LM27762DSSR switched capacitor voltage inverter. The circuit takes an input signal, compares it with a reference voltage, and outputs a digital signal indicating which voltage is higher. #project
