I have used python for establishing the I2C communication between the Rpi and PCF8591. It's compatible with our fancy Breakout Garden HAT (and This ADS1015 ADC (analog-to-digital converter) breakout has three channels that can read voltages from -24V to +24V at sampling rates up to 3. ADC resolution increased to 14-bit native for sample rates below 6 MHz, increasing to 16 bits with decimation Enhanced RF pre-selection (greater filter selectivity plus 4 additional sub-bands compared to the original RSP1) for reduced levels of spurious responses. Recommended for you. To evade this, use our Sensorkit X40 with the KY-053 module, which provides a 16 Bit ADC, which can be used with the Raspberry Pi, to upgrade it with 4 additional analog input pins. How come? First of all, why is the 3 MSPS ADC giving me only 380 KSPS and not something like 2 MSPS? Second, when I change the ADC to something that's about 70% faster, I get the same sampling rate, why is that? Is that the limit of the Pi?.
