TU-Darmstadt-APQ/RedPitaya-Lockbox
Digital controller for laser frequency stabilization based on the RedPitaya STEMlab 125-14 board
Boards in 3 GitHub repositories, designed in KiCad, that use the BUF634T by Texas Instruments (-2.25V~18V -40℃~+85℃ 1 1.5mA 100mV 100uV/℃ 180MHz 250mA 2V/ns 2uA 4nV/√Hz@10kHz TO-220-5 Operational Amplifier ROHS). See how each wires it, with its parts, size, README and files; the BUF634T’s symbol, footprint and pinout are on its own page.
