- 4 lpGBTv1: one as a master available through IC, three as slaves controlled through I2C controller of the master. Manual/description here.
- 4 GBCR2: all controlled through lpGBT master I2C controller. Manual here.
- 1 VTRx+: controlled through lpGBT master I2C controller. Description here.
- 1 bPOL2V5 carrier board: houses the bPOL2V5 ASIC that converts 2.5 V to 1.2V. Datasheets here.
Specific for SLAC's test-Optopanel will be marked in red.
Mechanics:
- Up to 8x Optoboards are housed in one Optobox. One Optobox consists also of:
- 1 Powerboard: hosts 5 bPOL12V ASICs (conversion 9 V to 2.5 V) and 1 MOPS chip
- 1 Connectorboard: handles power distribution form the 5 bPOL12V to the 8 Optoboards according the SP chain powering/detector layout.
- Up to 28x Optoboxes (14x normal, 14x mirrored) are housed in one Optopanel.
- Each side of the ITk has 4 Optopanels.
Currently specific for SLAC IS demonstrator:
4x Optoboards are housed in one Optobox. This Optobox is housed in a Test-Optopanel.

We collect support requests and general questions on our Mattermost channel Bern-Optoboard (invite link).
Optoboard software for FELIX:
We created a repository with scripting software to easily configure the Optoboard: https://gitlab.cern.ch/bat/optoboard_felix. A lot is documented in the readme and wiki of the repository.
In a currently ongoing effort by Bern PhD student Daniele dal Santo, the software will be integrated into the ITk demonstrator software itk-demo-sw.
Test-Optopanel at SLAC:
A collection of photographs from the test-Optopanel and its sister at CERN SR1 can be found here. See also this Twiki here of the SR1 test-Optopanel which has similiar information (but some very different configurations).

Connectors:
Banana plugs are labelled according to powered bPOL12V.
Cooling and dry air inlet/outlet: FESTO 8 mm
DCS:
Currently no MOPS is mounted on the Powerboard inside the test-Optopanel (due to availability). We will ship one as soon as we got our hands on them.
