+This pin is Flipper RX on LPUART [Low Power UART] (so connect to TX on device).
+
+For I2C devices this is SCL (Serial Clock) pin.
+
+For ADC devices this is ADC1.1 pin (flipperscope application uses LL library to show values.)
+
+Generic GPIO uses PC0.
+
+CHECK: "LPTIM1.IN LPTIM2.IN"

+Devices:
+- BME280[I²C] (SCL)
+- BH1750[I²C] (SCL)
