Introduction

This is a project that is based on Teensylu with heavy influence from Printrboard. The board has been completely redesigned with higher rated connectors, an onboard voltage regulator, uSD card slot, a mini blade fuse, and high power SMT mosfets. Power supply now uses either a 6 pin PCIe power connector, or a 4 pin screw terminal. USB is connected through a micro usb connector.

For 12v compatibility, the board MUST be made with 2oz copper layers. 24v can be done with 1oz layers. It is highly recommended to use a 24v supply as it is much safer with lower current. They are 2 versions of the board, 2 layer and 4 layer. Currently only the 2 layer version is supported.

Features

  • Small design - board is 4" x 3"
  • Teensylu clone, Atmel's AT90USB1286 - AT90USB1287 drop-in compatible for 20mhz support
  • Up to 4 Pololu stepper driver boards (or Pololu compatible) on-board (X,Y,Z,Extruder) (without voltage regulator)
  • Supports multiple power configurations (Carried from Sanguinololu)
-- Main power by either screw terminal or ATX PCIe 6 pin connector 12-28V
-- Logic supplied by onboard 5v switching regulator
-- Logic can also be supplied by USB bus (do not supply main supply at the same time, may damage board or your computer!)
-- on-board USB connectivity
  • 2 thermistor connectors with circuitry
  • 2 SMT N-MOSFETs for extruder/bed heaters
  • 1 Fused N-MOSFET for low power fan or motor
  • Selectable 12v/5v endstop voltage
-- 4 endstops including 4th stop called E-Stop to be used as an emergency stop, or extruder stop (to be added in firmware).
-- The Z endstop has been changed to a 4 pin design. Pin 1 now supplies 12-28v for inductive probe sensors. The input is 12v tolerant (has not been tested with higher voltages).
  • Edge connectors enabling right-angle connections
  • 14 Extra pins available for expansion and development.
-- TODO - List expansion capabilities
  • SMT Components sized at 0603 for easier soldering.
