Runs g2core codebase
-
Processor
- Atmel SAMS70N19A ARM Cortex M7 processor
- 300MHz internal clock
- 32 and 64 bit single instruction floating point hardware
- Multi-level cache, instruction pipeline, simultaneous instruction execution
- All communications IO is DMA driven
- USB is on-chip (our own drivers - very very field tested already)
-
Host and Communications
- USB-B connector for driving from "standard" external hosts
- Host expansion connector for Linux host carrier board
- Board design accommodates wide variety of linux hosts such as nano-Pi, Beaglebone, rPi, etc.
- Host-to-board communications via 4 wire UART - RX/TX/RTS/CTS
- 1.2 Amps 5v @ 1200 ma available for host processor
-
Motors
- 5x Trinamic TMC2130 stepper motor drivers
- Will handle up to 1.7 amps;
- Good for almost all NEMA17 motors, will do some NEMA23s
- 5x STEP / DIRECTION / ENABLE breakouts for external drivers (in lieu of Trinamics)
- selectable 3.3v/5v output levels
- 4x "hobby servo" PWM outputs (uses the buffered digital outputs)
- can be configured to interpret Gcode directly, or run as PWM devices
- 5x Trinamic TMC2130 stepper motor drivers
-
Inputs
- 10 input protected 3.3v digital inputs
- 4x analog to digital inputs
- configured as straight-through 0v-3.2v ADC channels
- external analog front-end boards can be used to run 100K thermistors, PT100, PT1000 RTDs
- OEM boards can be configured on-board for these front-ends
-
Outputs
- 4x buffered digital outputs - selectable 3.3v/5v level
- 4x low-power FET digital outputs - up to 300 ma each (fans, etc.)
- 2x high-power 6amp FET digital outputs - for extruders
- 1x high-power 20A FET digital outputs - for heated bed
- 0v-10v DAC output for spindle controller
- Neopixel LED array output with DMA firmware driver
-
Other
- Can be configured for separate 24v motor and logic input to support eStop that cuts motor power while leaving controller board and host live to handle whatever hit the fan.
- SPI and I2C expansion port
- Watchdog safety circuit to disable powered outputs
- Can remove motor/output power w/o killing logic power
- JTAG/SWD connection and real-time debugging using Atmel-ICE
- ROHS
