Introduction

This board can support up to 20 ADR1399 or LM399 voltage references. Using a DD-50 connector, these reference can be monitored using a multiplexer and a DMM. In combination with the 2000-SCAN SSR Replacement up to 10 references can be scanned using a Keithley Model 2002.

Design Files

For production

The design files required for the PCB production and assembly can be found on the releases page and include the following resources:

• Schematics as a PDF
• Gerber files
• Pick & place position files
• Bill of materials as a CSV file and also as an interactive HTML version

The latest revision of those files can be found here.

Versioning

I use SemVer for versioning. For the versions available, see the tags available for this repository.

• MAJOR versions in this context mean a breaking change to the external interface of the hardware like different connectors or functions.
• MINOR versions contain changes to the hardware that only affect the inner workings of the circuit, but otherwise the performance is unaffected.
• PATCH versions do not affect the schematics or invalidate older bill of materials. These changes may include updated components (to replace obsolete parts for example), an updated silkscreen, or fixed typos.
