3 line to 32 line output expander - SMT version
Yap Mar 05,2025
This project is described at Hackaday.The minimum lines required to use this board are: GND, SER (data), SRCLK (shift), RCLK (strobe). Vcc depends on the power arrangement. You should jumper the ~OESEL (output enable select) to ground if you don't wish to disable the display by signal, or vary the output with PWM, from a controller. The ~SRCLR input is only needed for resetting the output by the controller.This board is designed with optional aspects you can choose to include or not:As mentioned...

Macro_Keypad_w_RotEnc_ver4
Feb 12,2025
This is a Macro Keypad Keyboard platform that has 15 Cherry keys, 3 rotary encoders, an I2C port for 0.91 inch display, and sets of pins on the back side of the board to access power and all the other unused pins from the ESP32-S3-DevKitC-1-N16R8.This provides the ultimate in flexibility, to use the keypad as a wireless bluetooth remote, to control other internet of things (IOT) devices via WiFi, or to simply plug it into a USB port to act as a quick means to generate text and commands on your c...

Motor driver
Jan 11,2025
This project is a PCB design for a L298N?motor driver; the L298N is commonly used to control DC motors. This makes it more versatile than the commonly used L298N module, which has larger footprints and?requires more power to operate.1.Size and Bulkiness: Original design is bulky and not suited for?smaller builds.2.Separate Power for IC and Motor: The standard module?has separate power supplies for the IC and motor, which is wasteful.My goal was to combine a voltage regulator with it and to redes...
