I managed also yesterday to send some data to grbl via atmega8 so i probably put also some manual moving functionality in to it.
It basicly has every thing any driver should have just the microstepping is kinda weird. Single-channel PWM current control stepping motor driver.Īdvance the excitation step with the only step signal input. Output on-resistance (upper side : 0.25Ω lower side : 0.15Ω total of upper and lower : 0.4Ω Ta = 25☌, IO = 4.0A) Yeah i am using them right now but i need some more power so i decided make another shield using
