Description
This is a page for the pre-order of the V2 prime board which will be the final retail version. If you would like a board immediately please purchase the “kickstarter version” which is currently in stock.
Smoothieboard V2 Prime
MCU: STM32H745 265pin BGA
Stepper drivers: 4 onboard drivers with 2 options TMC2660 with an ideal current range of 1.2-2.2A TMC2590 with an ideal current range of 2.4-4.6A (may require heatsinking or fan)
Output MOSFETs: 4 single FETs all of which share a common highside PFET for additional shutoff capability. 1 Dual FET output for higher current outputs such as bed heaters
6 endstop/limit connectors with buffered and ESD protected inputs.
1 Probe input with Comparator input. Capable of 3-24v probes (higher voltage with expansion boards)
3 Buffered and ESD protected ADC inputs for thermistor temperature measurement
1 onboard thermistor for board temperature monitoring
5v@3a onboard regulator with output.
MSD pushbutton: If you press this button (or send the command) it will go into MSD mode and mount the board as a storage device until it is ejected by the host.
10/100 onboard ethernet with Magjack
SD card slot
USB Host (currently unused in firmware)
RTC battery (optional)
9 10-pin connector headers with various GPIO allowing for up to 63 pins of expansion.
All power inputs via XT30 connectors for easy connection.
Assembled in the United States of America using Foreign and Domestic parts (and designs)
