Boards using the HTS221
6 boardsBoards in 4 GitHub repositories, designed in KiCad, that use the HTS221 by STMicroelectronics (-40℃~+120℃ 0%RH~100%RH 1.7V~3.6V 16bit 2uA I2C、SPI ±0.5℃ ±3.5%RH HLGA-6(2x2) Temperature and Humidity Sensor ROHS). See how each wires it, with its parts, size, README and files; the HTS221’s symbol, footprint and pinout are on its own page.
