The interfaces of Dobot Magician are located on the back of the base and the Forearm respectively. Figure 4.1 shows the interfaces on the back of the base, and Table 4.1 lists the description.
Figure 4.1 Interfaces in the base
Table 4.1 Interface Description
| No | Description |
|---|---|
| 1 | Reset key: Reset MCU program |
| During resetting, the LED indicator on the base turns yellow. About 5 seconds later, if the LED indicator turns green, it indicates that the reset is successful | |
| 2 | Functional key: |
| • Short press: Start running offline program | |
| • Long press for 2 seconds: Starting homing procedure | |
| 3 | Communication interface/UART interface: Connect with Bluetooth, WIFI and so on the Dobot protocol is adopted |
| 4 | USB interface: Connect with PC |
| 5 | Power interface: Connect with power adaptor |
| 6 | Peripheral interface: Connect with air pump, extruder, sensor and other peripheral equipment. For details about peripheral interfaces, please see Table 4.2 |
