StepperChecker
About the StepperChecker PCB
StepperChecker is an open source PCB design by adammhaile, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 89.4 × 69.1 mm, with 26 components from 22 distinct parts.
Other key parts include the R-78E5.0-1.0 and FEATHER. By type, the board carries 14 connectors, 3 capacitors, 3 resistors, 2 ICs, 2 switches and 1 diode.
It belongs with the robotics & motion designs in this gallery.
From the project
StepperChecker is a stepper motor driver dev and test board, designed to be easy to build, setup, and use. It will take any stepstick style motor driver and any Feather compatible microcontroller board. The basic intent is to have firmware loaded that will move the motor forward
StepperChecker is a stepper motor driver dev and test board, designed to be easy to build, setup, and use. It will take any stepstick style motor driver and any Feather compatible microcontroller board. The basic intent is to have firmware loaded that will move the motor forward or reverse based on which button is pressed, at a sped defined by the potentiometer. But, of course, the sky is the limit given the many Feather boards available.
