Electrical Specification
| Parameter | Min | Typ | Max | Unit |
| Vin (PSU) | 9 | 12 | 18 | V |
| Current (Fuse Protected) (1) | 0.6 | (2) | Amps | |
| Input Isolation voltage [Vin vs GND(3)] | 1.6 | 2 | KV | |
| Operating Temp | -40 | 85 | ‘C |
- (1) – This is current of the Root CNC controller including exports power via output pins
- (2) – Dependant on configuration of external FETs and input switches
- (3) – GND is the isolated floating voltage on the Root CNC controller – do not connect this to chassis
Digital Output Electrical specification (Non isolated interface)
| Parameter | Min | Typ | Max | Unit |
| Vout (Root controller derived supply) | 4.95 | 5 | 5.05 | V |
| Ouput current | 150 | mA | ||
| IOH High-level output current(1) | 25 | mA | ||
| IOL Low-level output current(1) | 25 | mA | ||
| VOH High-level output voltage(2) | 3.8 | V | ||
| VOL Low-level output voltage (3) | 0.55 | V |
- (1) This parameter max the Root CNC controller extremely well suited to drive opto-isolated stepper motor drivers (special sauce)
- (2) – Over full operating specification and at max current draw (-32mA)
- (3) – Over full operating specification and at max current draw (32mA)
Dimensions – PCB
Dimensions – Case
The case is designed to house the Root CNC controller REV 1 to protect against accidential dammage to the PCB, whilst allowing access to the screwless connections and connectors.
The case is designed to be 3D printed and allows the unit to be DIN rail mounted (ADD link to derived source)
