El Controlador de Motor Paso a Paso Bipolar Simple A4988 Pololu 2A 8-35V es una placa de componentes para el controlador de motor paso a paso bipolar A4988 fácil de usar de Allegro y es un reemplazo directo para el portador de controlador de motor paso a paso A4983. El controlador presenta limitación de corriente ajustable, protección de sobreintensidad y cinco resoluciones diferentes de microstep.
Esta placa para el controlador de motor paso a paso bipolar A4988 de Allegro cuenta con protección de limitación de corriente ajustable, sobrecorriente y sobretemperatura, y cinco diferentes resoluciones de microstep (hasta 1/16 de paso). Funciona de 8 V a 35 V y puede entregar hasta aproximadamente 1 A por fase sin un disipador de calor o flujo de aire forzado (tiene una capacidad de 2 A por bobina con suficiente refrigeración adicional). Esta placa se envía con clavijas macho de 0.1 "incluidas pero no soldadas.
Características : • Interfaz de paso simple y control de dirección • Control inteligente de corte que selecciona automáticamente el modo correcto de caída de corriente (decaimiento rápido o decaimiento lento) • Cinco resoluciones de pasos diferentes: paso completo, medio paso, cuarto de paso, octavo paso y decimosexto paso • Apagado térmico por sobretemperatura, bloqueo de bajo voltaje y protección de corriente cruzada • Protección de cortocircuito a tierra y de cortocircuito en carga
Needed to add heat sinks at the bottom of the pcb where the thermal vias are and a copper heat sink on the top of the chip; the way I've used it temps got >>80 degrees C; now it works fine. Sometimes my steppers are showing strange things (stepping back instead of forward); probably a temp thing because it only happens after driving them for a while. For "lights" stuff this is more than ok!

Easy to use
Pretty much plug and play by following the pin layouts on the datasheet. Only requires step and direction inputs to run. Works with bipolar and unipolar stepper motors. More info can be found on the pololu page.

Works great and small size
Perfect size to snap a couple of these into a bread board for testing stepper motors
