Duet 3 Expansion 3HC

Beschreibung

Das Duet 3 Expansion 3HC (High Current) dient als Erweiterungsplatine zum Duet 3 Mainboard 6HC und ist mit seinen leistungsstarken TMC 5160 Schrittmotortreibern in der Lage Motoren mit bis zu 6A direkt anzusteuern. Dank der Daisy-Chain Topologie der CAN-BUS Schnittstellen können mehrere Expansion Boards hintereinander geschalten werden.  

Aktuelle Board Version: v1.02a

Features

• Powerful 32 Bit Processor: Atmel ATSAME51N: ARM Cortex-M4F microcontroller running at 120MHz, with 512Kb flash memory, 384Kb RAM and many peripherals.
• Three high-current advanced TMC5160 stepper drivers: SPI controlled will all the latest Trinamic features. Maximum motor current 6.3A peak per phase (4.45A RMS).
• One CAN-FD BUS for connection to the main board
• Triple extruders: 3 medium current heater channels for up to 3 extruders.
• 6 PWM controllable fan channels. 3 of these support 4 wire fans including tacho reading. These can be run from either the input voltage, from 12V, or from external power for added flexibility. Also one always-on fan connector supplied with VIN voltage.
• Fuse fitted for input power
• Automatic ADC gain calibration for thermistors allows for accurate and repeatable temperature setting. PT1000 sensors are supported in addition to thermistors. In addition PT100 and Thermocouples are supported through SPI daughter boards.
• Power monitoring to allow for state save on power fail.
