The nRF54L15 DK has a range of solder bridges for enabling or disabling functionality on the nRF54L15 DK.
When cutting a closed solder bridge to make it open, be careful not to damage other parts of the nRF54L15 DK.
The following table is an overview of the solder bridges on the nRF54L15 DK.
| Solder bridge | Default | Function |
|---|---|---|
| SB1 | Open | Short to connect RESET button line to nRF54L15. |
| SB2 | Closed | Cut to disconnect debugger from the RESET button line. |
| SB3 | Closed | Cut to disconnect the 32.768 kHz from P1.00. |
| SB4 | Closed | Cut to disconnect the 32.768 kHz from P1.01. |
| SB5 | Open | Short to enable P1.00 as GPIO. |
| SB6 | Open | Short to enable P1.01 as GPIO. |
| SB8 | Open | Short R23, 100 k pull-up resistor to the RESET button line. |
| SB9 | Closed | Cut to disconnect VDD:IO from U9 external flash power. |
| SB10 | Open | Short to connect U9 external flash to VDD:nRF domain. |
| SB11 | Closed | Cut to connect U9 permanently to the nRF54L15 SoC. |
