Yes I understand, The L293d is basically the same thing. You can just wire it up and it will act like the same module. The logic voltage level is between 2.7v to 5.5v. For speed control I get max speed at 5v and half speed at 2.5v if i am suppying a pwm instead of a HIGH or LOW. But can a 3.3 v...

Thanks for the detailed explanation. I am also concerned about the 3.3v pwm. Is the 3.3 pwm enough for controlling motor speed while using motor driver ICs like l293d? Or should I convert it to a 5v pwm using opamps circuits? Or Is the 3.3 v enough to drive the transistors in l293d to...

Yes, I am talking about PWM input to a motor driver like L293D H bridge IC. It needs 5v on the control lines and PWM controls the motor speed. The current is not sourced by the MCU itself. So How can i change the 3.3v PWM to 5v PWM?

5v output On second thought, the Atmel AVC can be programmed using C rather than the Arduino coding which gives access to the timers and other registers easily. But I dont see any info about the timers and registers of teensy 3.1 in pjrc website. Also Teensy 3.1 output voltage is 3.3v. Doesnt...

I am thinking of buying a teensy soon. The Teensy++ 2.0 is costlier than the Teensy 3.1 but the Teensy 3.1 is so much faster and has more memory! Can someone explain why? :confused:
