Description
AMIS-30543 Stepper Motor Driver Carrier#2970 This is a breakout board for ON Semiconductors AMIS 30543 microstepping bipolar stepper motor driver, which features SPI adjustable current limiting, 11 step modes (from full step through 1 128 step), back EMF feedback that can be used for stall detection or optional closed loop control, and over current and over temperature protection. The board operates from 6 V to 30 V and can deliver up to approximately 1. 8 A per phase without a heat sink
#2970
This product is a carrier board or breakout board for ON Semiconductor’s AMIS-30543 Micro-Stepping Motor Driver; we therefore recommend careful reading of the AMIS-30543 datasheet (495k pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 3 A output current per coil (see the Power Dissipation Considerations section below for more information). Here are some of the board’s key features:
- Standard step and direction control interface
- SPI interface for configuring settings (e.g. step mode, current limit, sleep) and reading status registers
- Speed and load angle output that can be used for stall detection or closed-loop control of the torque and speed based on the load angle
- Eleven different step modes: full-step (uncompensated, compensated 1-phase, or compensated 2-phase), half-step (uncompensated or compensated), 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/64-step, and 1/128-step
- SPI-programmable current control (from 132 mA to 3 A) enables your microcontroller to adjust the peak-current limit on the fly as more or less torque or speed is needed
- Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
- Low-EMI PWM with SPI-selectable voltage slopes
- Compatible with 5 V and 3.3 V microcontrollers
- Integrated 5V regulator that can be used to supply an external microcontroller
- Integrated watchdog function
- Open coil detection
- Thermal warning indicates when the driver is close to the thermal shutdown temperature
- Over-current status and shutdown (short-to-ground and shorted-load protection)
- Reverse voltage protection

Confirmed copper by measurement
Size: 2 Colors each 10FT, Style: 10AWG, Size: 2 Colors each 10FT, Style: 10AWG
There are many fake "copper" wire products on Amazon these days, which are not actually copper. Some are even supposedly tinned, but what is inside may be an alloy of copper like brass, so you can't even trust color or color of the cut ends of the wire. This wire, as of April 2021 at least, is actually copper, per 4 wire resistance measurement using Kelvin clips. A 10 foot piece of 10 gauge should read .01 ohms, and this wire does.

Size: 2 Colors each 10FT, Style: 10AWG
10ga. wire in red & black colors as advertised. Product came quick & unharmed. The wire itself is perfect for finding its way through the contours of my vehicle becaue of its "rope-like" feel (unlike a stiff wire). Would buy again, because so far, so good. Hope that helps.

Nice cables, thick
Size: 25FT, Color: Black+Red+Blue+Brown
Great quality, but due to being CCA those won't fit most 10awg crimps, will need 8awg crimps.
