3Pcs CJMCU-ADS1115 16Bit من Mod قسم التطوير ADC

4 channel 16bit ADC with 2-wire interface although not particularly fast is ideal for many projects. PGA is good for ADC of bridge outputs as differential mode is supported internally. For single-ended 0-5V signals more than half the range is lost as the scale is +/-6.144V (to handle possible differential signals) but still results in a resolution of 187uV - far better than most applications require. Measured voltages appear very stable, i.e. very little noise. Beware of using the Arduino I2Cdev library with I2CDEV_BUILTIN_FASTWIRE (default) operation. It doesn't work correctly. I suspect it is too fast for the ADS1115. However using wire (uncomment I2CDEV_ARDUINO_WIRE) is fine.
