3D Printer Accessories Arduino MEGA Shield Control Board Package weight: 0.05 kg Descroption: This board is for Arduino MEGA as Ultimaker UltiStepper drive and compatible with Pololu stepper driver boards. You can add as many stepper driver carriers as you need. It is very similar to other Pololu based electronic implementation, including RAMPS, but it can support up to five steppers (three for X, Y, Z, one for an extruder and one for any other function.) It is designed to run at a higher voltage than 12 volts, which allows you to put 90 Watts out of one MOSFET and run your stepper motors with more torque and higher maximum speeds. Features: Plug in all motors with simple 4-way JST connectors. Made for Ultimaker's UltiStepper Driver. Compatible with Pololu stepper driver boards. Configurable step sizes by placing jumpers. 3 x 55 Amp MOSFETs outputs (with LED indicators. Actual current capability limited by PCB and connectors). All pins are broken out for maximum extensibility. Runs from 15V to 19V. Three thermocouple inputs, or thermistor inputs. (The 100K thermistor is recommended). Has a IDC header for adding an LCD panel. Has a header for adding an SD card module. A toggle - switch for powering up / down the board. Easier to wire up thermocouples. Includes a 12V regulator for an (always on) fan to cool the electronics. A PWM output with power for LED arrays and other lighting. LCD backlight dimming can be software controlled. A serial I/O header for bluetooth and ethernet add-ons. Servo outputs for experimental setups. They need to be interrupt or software driven as the pins routed to the servo header I/O do not have PWM. Note: When the jumper (closer the VR-tube 7812TV) is connected, the power of Arduino MEGA Ultimaker Shield also will power up the Mega.

CJMCU-3386 MC33186DH1 Automotive Computer Board Idle Speed Throttle Drive Board Package weight: 0.00 kg Description: The 33886 is a monolithic H-Bridge ideal for fractional horsepower DC-motor and bi-directional thrust solenoid control. The IC incorporates internal control logic, charge pump, gate drive, and low RDS(ON) MOSFET output circuitry. The 33886 is able to control continuous inductive DC load currents up to 5.0 A. Output loads can be pulse width modulated (PWM-ed) at frequencies up to 10 kHz. A Fault Status output reports undervoltage, short circuit, and overtemperature conditions. Two independent inputs control the two half-bridge totem-pole outputs. Two disable inputs force the H-Bridge outputs to tri-state (exhibit high impedance). The 33886 is parametrically specified over a temperature range of -40°C ≤ TA ≤ 125°C, 5.0 V ≤ V+ ≤ 28 V. The IC can also be operated up to 40 V with derating of the specifications. The IC is available in a surface mount power package with exposed pad for heatsinking.
