Product Description Universal Motor Driver P2 Add-on Board Overview: The Universal Motor Driver P2 Add-on Board was designed as an accessory for the Parallax Propeller 2 eight-core microcontroller. It is compatible with standard P2 dual-port accessory headers found on the Propeller 2 Evaluation Board (#64000), P2 Edge Module Breadboard (#64020), and P2 Edge Mini Breakout Board (#64019). This 4-phase motor driver add-on supports experimentation and development with many motor types, including brushed and brushless motors. For example, it could support a single brushless 3-phase BDLC motor, a 4-phase stepper motor, or two standard brushed (2-wire) DC motors. It is the recommended motor driver for the 6.5″ Hub Motor with Encoder. For example, it could support a single brushless 3-phase Hub Brushless DC (BDLC) motor, a 4-phase stepper motor, two brushed bi-directional DC motors or four brushed uni-directional DC motors. With a 3-phase motor, both sinusoidal 180° and classic 120° drive techniques are supported. The open design and standard 0.1” connectors allow the Universal Motor Driver P2 Add-on Board to be used with other microcontrollers as well. Features: Universal 4-phase motor driver using four UCC27211D MOSFET drivers Phases can be controlled individually or in groups to support many motor types including single or 3-phase motors, single/dual DC motors or 4-phase stepper motors Sinusoidal 180° or classic 120° drive topology Each phase allows individual control of High and Low sides High and Low sides protected against simultaneous activation On-board Hall effect sensor connector for motor control feedback Common current feedback signal for motor control and over-current protection Independent voltage feedback signals for each phase, for motor control and over-voltage protection Under-voltage protection built into the MOSFET drivers High-current spring terminal connectors for quick and robust connections to high-current motors Two grounded 0.125 inch (3.2 mm) mounting holes PCBs assembled, tested, and completed in Rocklin, California Universal Motor Driver P2 Add-on Board Specifications: Input voltage range: 6–40 VDC Maximum continuous supply current: 20A Maximum surge motor current: 60A P2 board connector: dual 2×6 pass-thru headers with 0.1″ spacing Power and motor cable connection method: Push-in spring connection, nominal 2.5 mm² Communication Interface: 3.3V TTL, PWM VIN and Output Channel Spring Terminal Blocks: 32 A 400 V rated Conductor cross section solid : 0.2 mm² – 4 mm² Conductor cross section AWG : 24–12 Stripping length : 10 mm Operating temperature range: -40 to 185 °F (-40 to 85 °C) PCB dimensions: 2.75 x 2.75 in (70 x 70 mm)
