This is a bulk-packaged version of our Black Edition A4988 Stepper Motor Driver Carrier that ships with 0.1″-pitch male header pins installed as shown in the main product picture, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard. Please see the Black Edition A4988 Stepper Motor Driver Carrier product page for more information about the driver.

This bulk-packaged version is intended for customers interested in higher volumes at lower unit costs. We will manufacture these to order, and quantities shown in stock will be limited to 10 units. We generally expect orders of up to a few hundred units to ship within a few days. For larger orders, please contact us for lead time estimates.
