Boards using the CJ431

24 boards

Boards in 21 GitHub repositories, designed in KiCad, that use the CJ431 by Jiangsu Changjing Electronics Technology (CJ) (-25℃~+85℃@(Ta) 100mA 1mA 2.5V~36V 50ppm/℃ Adjustable Parallel ±0.5% SOT-23 Voltage Reference ROHS). See how each wires it, with its parts, size, README and files; the CJ431’s symbol, footprint and pinout are on its own page.
