Category: 12 x PWM

Hat With 12 individual PWM signals capable of 60V and 2A. Each equipped With an independant, high side current sensor and separate terminal output With PWM and Ground. Perfect for running small 3-Phase or Stepper motors With full current sensing.

BasicPI Firmware Stack

This illustrates the BasicPI Firmware Stack in progress. What I always do in embedded applications is to make a “standard” main.cpp as follows: void AppInit() {    // wire hardware } int main() {    AppInit();    // start OS } A team I worked in years ago agreed on this standard so we should…

12 x PWM Hat

 This 12 x PWM Hat have 12 x high side current sensors. The PWM driver have a separate PSU, DRV8313 is rated 60V and INA194 is rated -16 to 80V so they are not that easy to break giving the Hat a very decent protection level. A separate TVS and capacitor bank on motor PSU…
