M8 Connector on Tracker One
Facing pins on the panel connector from the outside of the case
The 8-pin connector has these signals:
|3||Analog A3||GPIO D3||IO1||White|
|4||Serial1 RX||Wire3 SDA||GPIO D8||IO1||Green|
|5||Serial1 TX||Wire3 SCL||GPIO D9||IO1||Brown|
1MCU GPIO is limited to 3.3V maximum.
2CAN Bus specifications can be found in the Tracker SoM datasheet. CAN Bus termination is provided on the carrier board.
36.0 to 30 VDC at 2A when using the M8 connector.
45V, 400 mA maximum. Controlled by the
You typically connect the cable to your custom external interface device by routing the cable through a cable gland in your enclosure and to your custom board and:
- Terminate with pins in a PHR-8 to mate with a B8B-PH on your expansion board
- Terminate with screw terminals on your board
- Terminate by soldering the wires to your board
For more information on expanding your Tracker One using the M8 connector, see the Tracker One Expansion Tutorials.
The M8 cables provide a convenient way to connect external devices to the Tracker One while preserving the IP67 waterproof rating and not having to disassemble the Tracker One.
|M8 Pin||Function||Color||Wire Gauge|
|Length||1 meter ±3 cm|
