Boards in 3 GitHub repositories, designed in KiCad, that use the TL074IDT by STMicroelectronics (-40℃~+125℃ 1.4mA 100pA 13V/us 15nV/√Hz@1kHz 20pA 3MHz 3mV 5uV/℃ 60mA 6V~36V 86dB Four channels Short-Circuit Protection、Built-in compensation、Latch-up suppression SOIC-14 FET Input Amplifiers ROHS). See how each wires it, with its parts, size, README and files; the TL074IDT’s symbol, footprint and pinout are on its own page.
marcoallegretti/Teresina-Rack
The goal is an open, self-fabricatable Daisy Patch SM-compatible Eurorack submodule: the same carrier interface and libDaisy application compatibility through a small Teresina firmware variant.
lepton-7/Open-Plate-Spectrophotometer
An open-source project to build a 96-well spectrophotometer operating at 620nm. Designed from the ground-up focusing on robust electronic design.
