OCXO breakout
About the OCXO breakout
OCXO breakout is an open source PCB design by Quantum-Electronic-Devices, published on GitHub under the CERN-OHL-W-2.0 license. It is a 4-layer board measuring 72 × 32 mm, with 13 components from 12 distinct parts.
Other key parts include the LT3045IDD#PBF. By type, the board carries 4 capacitors, 2 connectors, 2 resistors, 1 IC and 1 crystal.
It belongs with the dev boards & breakouts designs in this gallery.

- KiCad footprints - KiCAD 3D models - KiCAD schematic libraries
- 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.
