Bottom Connector - Programming & CAN OUT¶
Connector Part Number: SM08B-GHS-TB
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | GND | Signal Gound |
| 2 | SWDIO4 | Programming Pin - SWDIO Motor 4 |
| 3 | SWDIO3 | Programming Pin - SWDIO Motor 3 |
| 4 | SWDIO2 | Programming Pin - SWDIO Motor 2 |
| 5 | SWDIO1 | Programming Pin - SWDIO Motor 1 |
| 6 | SWCLK | Programming Pin - SWCLK, Shared by all Motor MCUs |
| 7 | CAN_L_OUT | CAN OUT Signal LOW - If using DroneCAN |
| 8 | CAN_H_OUT | CAN OUT Signal HIGH - If using DroneCAN |
Warning
If using DroneCAN and this ESC is in-line with another downstream node, please ensure the signal is passed through the ESC using the CAN IN and CAN OUT signals to ensure no stubs on the CAN bus. If the ESC is the last node on the bus, then a termination resistor must be used.
