Open-source electronics ecosystem for optical atomic clocks

We present an open-source hardware and software ecosystem for optical atomic clocks. We provide PCB schematics and fabrication files for manufacturing the most important electronic systems together with the required software. The boards are designed for an active bad-cavity superradiant strontium clock and a passive optical lattice strontium clock, but they can be easily adapted to other atomic species' optical atomic clocks or ultra-cold atoms' systems like magneto-optical traps or Bose–Einstein condensate setups.
