Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/DFR1199:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The 28BYJ-48 Stepper Motor Module is an all-in-one motion control solution that integrates a geared stepper motor with a high-performance A4988 driver on a single circuit board. This integrated architecture fundamentally simplifies implementing precise motor control by eliminating complex wiring and providing a secure mounting system. Operating at 5V, this geared stepper motor offers high-torque, precise positioning with a 1/64 gear ratio, making it an excellent component for STEM educational settings, rapid prototyping, and beginner projects with popular microcontrollers like [Arduino](https://core-electronics.com.au/arduino.html), [Raspberry Pi](https://core-electronics.com.au/raspberry-pi.html), and [ESP32](https://core-electronics.com.au/development-boards.html#category_2184). **All-in-One Design: Motor and Driver on a Single Board** To accelerate project development, this stepper motor's control interface has been streamlined to just four essential pins: STEP, DIR, 5V, and GND. This simplified approach allows for immediate connection to any standard microcontroller. Users can achieve precise control over the motor's step and direction without the steep learning curve associated with traditional multi-wire stepper motor setups, getting their projects moving in minutes. **Plug-and-Play: Simplified 4-Pin Interface** To further accelerate project development, this stepper motor's control interface has been streamlined to just four essential pins: STEP, DIR, 5V, and GND. This simplified approach allows for immediate connection to any standard microcontroller, such as an Arduino orRaspberry Pi. Users can achieve precise control over the motor's step and direction without the steep learning curve associated with traditional multi-wire stepper motor setups. **Robust Mounting for Stable Operation** Engineered for stable and secure installation, the motor driver board features four M3 nuts permanently affixed to the PCB. This built-in mounting system allows the entire motor assembly to be firmly fastened to a project chassis or structural component with standard screws. This design ensures that the 28BYJ-48 motor remains stationary during operation, which is critical for applications requiring consistent and repeatable mechanical movement. ### Specification - Operating Voltage: 5V DC - Physical Interface: 4-Pin (STEP, DIR, 5V, GND) - Motor Type: 28BYJ-48 Geared Stepper - Integrated Driver: A4988 - Gear Ratio: 1:64 - Steps per Revolution (Output): 4096 (based on half-step mode; microstepping supported for smoother motion) - Holding Torque: 0.9 kgf·cm - Detent Torque: 0.5 kgf·cm - Mounting: 4x Integrated M3 Nuts - Dimensions: 42mm x 42mm ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/D/F/DFR1199-1.jpg)
