Unqiue IDs
Programming Unique IDs in the OTPs is not rolled-out in Production
Currently KED factory production does not write the IDs to the OTPs. The following description is therefore a draft and will be implemented in factory software in 2024.
The KED Unique-IDs of the SoM and baseboard are stored in the OTP fuses.
| ID | Fuse Register | Format |
|---|---|---|
| KED SoM Unique ID | GP1 | Integer, Big-Endian |
| KED Board Unique ID | GP2 | Integer, Big-Endian |
Layout and Connectors
Digital IOs
Four digital inputs/outputs are available. The table below shows number and function of available DIOs and their associated GPIOs.
Each DIO has one GPIO that switches a MOSFET driver against the supply (24V) rail and another GPIO to read back the voltage level via a resistor divider.
| DIO Name | Function | GPIO Name | GPIO Label | GPIO Device | GPIO Offset | Connector |
|---|---|---|---|---|---|---|
| DIO1 | drive | GPIO1_IO03 |
- | gpiochip0 | 3 | X13 - Pin 1 |
| DIO1 | read | GPIO1_IO06 |
- | gpiochip0 | 6 | X13 - Pin 1 |
| DIO2 | drive | GPIO1_IO07 |
- | gpiochip0 | 7 | X13 - Pin 3 |
| DIO2 | read | GPIO1_IO08 |
- | gpiochip0 | 8 | X13 - Pin 3 |
| DIO3 | drive | GPIO1_IO09 |
- | gpiochip0 | 9 | X13 - Pin 5 |
| DIO3 | read | GPIO1_IO10 |
- | gpiochip0 | 10 | X13 - Pin 5 |
| DIO4 | drive | GPIO1_IO11 |
- | gpiochip0 | 11 | X13 - Pin 7 |
| DIO4 | read | GPIO5_IO02 |
- | gpiochip4 | 2 | X13 - Pin 7 |
