The Raspberry Pi has Arduino no analog inputs and/or ADC (analog Digital Converter) in the chip of the Raspberry Pi are integrated. This limits the Raspberry Pi, if you You would like to use sensors, in which values are not digital sound. Solve this problem with this analogue/digital converter. This converter is also in the seno set, part number: 1413759. This module has a with 16-bit exact ADC, which you can use these to the Raspberry 4 analog inputs to expand You can. It is via I2C to the Raspberry Pi connected, takes over the analogue measurement and returns the value digitally to the Raspberry Pi. https://elecena.pl/product/28015820/joy-it-raspberry-pi-add-on-pcb-with-16-bit-adc-for-analogue-inputs 2025-03-12 https://elecena.pl/product/28015820/joy-it-raspberry-pi-add-on-pcb-with-16-bit-adc-for-analogue-inputs 2025-05-22 https://elecena.pl/product/28015820/joy-it-raspberry-pi-add-on-pcb-with-16-bit-adc-for-analogue-inputs 2025-09-17 https://elecena.pl/product/28015820/joy-it-raspberry-pi-add-on-pcb-with-16-bit-adc-for-analogue-inputs 2026-01-29
