But it is limited to mA, see below. We’ll notify you when there are updates to this product. So, in the case of a pin-to-adjacent-pin short, the device does not cause smoke or fire.

Simply inputting one pulse on the STEP input drives the motor one microstep. It can handle up to 1A as it is and 2A with cooling fins, fans, etc. Navigation menu Personal tools Create account Log in. Have an idea how to further improve this product?

The A interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.

Privacy policy About RepRap Disclaimers. Internal circuit protection includes: But you can also leave it as it is to get a more robust operation, at the expense of higher torque, heat stpper noise.

A4982: DMOS Microstepping Driver with Translator and Overcurrent Protection

It also operates step;er from 2. AUX2 is a pin 2×7 header at the left of the board. However unlike for example the TMC and TMC there is no simple means to control the maximum current or the micro-stepping.

Also, if all connectors and through-hole components capacitors, power connector are placed on the underside bottom of PCBthere is room on the rear of the PCB to place heat-sinks as well just underneath each A’s Exposed Pad. These are made to drive any stepper motor like NEMA17 type motorsin either full, half, quarter, or sixteenth micro-step s4982.

Mixed decay current control results in reduced audible motor noise, increased step accuracy, and reduced power dissipation. Internal synchronous rectification control circuitry is provided to improve power dissipation during PWM operation.


But it is limited to mA, see below. It uses the same 0. The A includes a fixed off-time current regulator which has the ability to operate in slow or mixed decay modes. The translator is the key to the easy implementation of the A The stock settings are for the x, y, a, b steppers and 50 for the z-axis.

ADual Stepper Board – RepRap

This would give sgepper thermal dissipation than putting the heat sink on the insulated package, yet at the same time allow stepper board stacking clearance of around mm.


Also the STM8 which is optional may be programmed to run completely independently, potentially running its own G-Code firmware and being controlled through standard reprap G-Code motion control software pronterface, Cura etc. Pin 1 is marked bottom right, row 9.

After Februarythe Rsense is changed from 0. The SPI pins of this header are unused and should not be connected.

A stepper motor controller (HCMODU) –

MS1 and MS2 jumpers were left in. However, with the number of available pins being so limited this idea had to be dropped. A 48x68mm expansion board providing two 2. Click the image to view larger. These drivers are hard to come by afterwhen MakerBot Industries stopped making them.
