Board Jumpers & Config

TRM_ON/TRM_OFF

Enables or disables termination. If BlueSCSI is the last device on the SCSI bus it should be in the TRM_ON position.

S1/S2

Configuration jumpers - Currently unused but will be used in future updates.

BOOTSEL (On Pico)

Used to enter flashing mode. Hold and then plug in the USB connection to your computer. The Pico module will appear as a USB drive, and you can now flash .uf2 files from the release page by dragging them onto it. See Updating Firmware.

SW1

Reset the SCSI Bus - not normally needed by an end user.

PWR_ON

(Desktop design only) Normally there is a jumper installed here, passing power from the berg and SCSI termpower line into BlueSCSI. If you are using USB to power BlueSCSI when installed, this jumper can optionally be removed to isolate from the SCSI bus and berg power sources.

BACK_FEED

(Desktop design only) If you would like 5v fed back into the SCSI termpower line, install a jumper here. Normally not required.

SDBG

(Desktop design only) For Serial debugging. Not normally needed, because USB debugging is available.

External LED Brightness Adjustment (Desktop Version 2023.03a and later)

To increase external LED brightness a little, bridge solder jumper JP1.

To increase brightness a lot, bridge solder jumper JP2.

Do not bridge both solder jumpers! This will cause LED damage.
