![]() ![]() You'll also need a SMT soldering toolkit to construct this board. You'll need a soldering toolkit to do most of this. I found that it is much easier to solder SMT boards in this fashion than to solder pin after pin manually with through-hole components. Using a technique such as solder paste + hot plate, the board becomes ridiculously easy to solder. The board is very easy to put together, even for a beginner. We used 1206 sized resistors and the A3982 itself is in a SOIC package. The downside is that the board is mostly SMT, although we made a conscious design decision to stick with some of the largest and easiest to solder SMT components on the market. Much cheaper and smaller than the L297/L298 (about $10 cheaper, total!) ![]() Superior DMOS technology (no heatsink required!)īuilt-in diodes and synchronous rectification (no large diode array!) Only one chip to solder, as opposed to the two chip L297/L298 combo The A3982 offers a number of improvements: This board was designed to improve upon and replace the v1.x series of stepper drivers which are based upon the venerable L297/L298 stepper drivers. The A3982 is capable of driving up to 2A per coil. It is based around the Allegro A3982 Stepper Motor Driver with Translator. ![]() This board allows you to control one stepper motor, as well as receive input from two limit switches. ![]()
