Hi, I'm going to control a stepper motor with Raspberry PI. ***Motor 42BYGHW609 Rate Voltage - 3.4 V Rate Current - 1.7 A Lead Wire - 4 ***Pololu A4988 driver Minimum operating voltage: 8 V Maximum operating voltage: 35 V Continuous current per phase: 1 A Maximum current per phase: 2 A Minimum logic voltage: 3 V Maximum logic voltage: 5.5V Microstep resolutions: full, 1/2, 1/4, 1/8, and 1/16 The main purpose of this post is that I receive useful tips. If will supply the driver with a phone charger (see image) 12V - 500mA it's ok? Is nesessary a electrolytic capacitor? If I increase or decrease voltage/current what will wappen?[attachment 60157 Photo0039.jpg] https://reprap.org/forum/read.php?262,546691,546691#msg-546691 Sun, 13 Sep 2026 12:44:59 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,546691,546862#msg-546862 https://reprap.org/forum/read.php?262,546691,546862#msg-546862 -Olaf]]> o_lampe Printing Tue, 18 Aug 2015 02:16:10 -0400 https://reprap.org/forum/read.php?262,546691,546691#msg-546691 https://reprap.org/forum/read.php?262,546691,546691#msg-546691
