Usada para alguns testes, mas esta como nova.

Processor - ATSAM4E8E
Processor features - 120MHz ARM Cortex M4F, 512Kb flash, 128Kb RAM, hardware floating point (single precision), DMA, 2Kb cache
Networking - 2.4GHz WiFi, WPA-2 encryption; USB port; serial port
On-board Stepper drivers - 5 x TMC2660
Stepper driver features - Up to 2.4A peak current, up to x256 microstepping, optional x16 interpolation on x16 microstepping, stall detection
High current outputs - 1 x 15A1, 2 x 6A each
Medium current outputs - 3 x PWM-controlled outputs, 2 x always-on outputs, voltage selectable between VIN, 5V or external supply (all outputs together), total current limit 1A2; 6 more PWM-controlled outputs on expansion board
Thermistor/PT1000 inputs - 3, optimised for 100k thermistors, can support PT1000 sensors with reduced accuracy
Inputs/Outputs - 5 on-board I/O connectors for endstop and filament monitors (STP pins are 8V-tolerant on revision 1.04 and later), 7 more on expansion header
Endstop or filament monitor inputs See under Inputs/Outputs
Z probe connector - 4-pin with IN/GND/MOD/3V3 pins (IN pin is 30V-tolerant in revision 1.04 and later)
Endstop status LEDs Yes
Power monitoring - VIN voltage and input to on-board 5V regulator, allows for state save on power failure.
SD card interface - On-board high speed (20Mbytes/sec) SD card socket.
