Nocodephprobe
cristoper/nocodephmeter
A pH meter for use with inexpensive pH probes (for gardening, home experiments) with temperature compensation and digital readout but no microcontroller
Boards in 6 GitHub repositories, designed in KiCad, that use the TLV272D by onsemi (-40℃~+125℃ 145dB 2 2.7V~16V 2.8V/us 200pA 2pA 2uV/℃ 30nV/√Hz@1kHz 3MHz 3mV 410uA 60mA Rail-to-rail output SOIC-8 Operational Amplifier ROHS). See how each wires it, with its parts, size, README and files; the TLV272D’s symbol, footprint and pinout are on its own page.
