Duet 2 WiFi-External Antenna v1.06

First released in 2016, this is the latest revision of the established Duet 2 machine controller. Using our advanced and regularly updated RepRapFirmware it is capable of controlling 3D printers, CNCs and a wide range of other machines. It has been the controller of choice for hobbyists and advanced machine designers alike since its launch. As of January 2024 the Duet 2 controller is not recommended for new designs, and it is recommended to use of the Duet 3 range for new designs going forward. The Duet 2 Wifi with Internal Antenna is End Of Life and no longer available directly from us, although some reseller may have limited stock. The Duet 2 Wifi with External Antenna and Duet 2 Ethernet are now Special Order products although we have some limited stock available on a first-come first-serve basis. Please contact us for pricing, availability and lead time.

Features	Specifications
Processor	Microchip ATSAME51G19A
Processor features	32-bit, 120MHz ARM Cortex-M4F, 512Kb flash, 192Kb RAM, hardware single precision floating point unit
Networking/Comms	CAN-FD BUS for connection to the Duet 3 Mainboard. Optional on-board CAN bus termination.
On-board Stepper Driver	1 x TMC2160A
Stepper Driver features	SPI controlled, can be run in open loop or closed loop mode. Maximum motor current 6.3A peak per phase (4.45A RMS)
Encoder Inputs	Single Ended/Differential Quadrature or SPI bus
Thermistor/PT1000 inputs	2 x thermistor/PT1000 inputs. This is intended to allow for motor temperature monitoring, potentially coupled with a cooling system controlled by one of the outputs
Medium current output	1 x medium-current (2.5A max) output at V_FUSED or VA_FUSED (V_AUX with fuse protection) voltage, with PWM capability and built-in flyback diodes
Brake output	1 x Brake Solenoid (1A max) output at V_FUSED or VA_FUSED voltage. This circuit is designed to turn on/off very quickly to allow for fast brake engagement. It has PWM capability so can be configured to support 24V brakes when V_IN is 48V. Alternatively provide V_AUX at 24V for the brake. (note before v2.0 this output was OUT1 so could be used for a brake or other purpose, without the fast turn off)
