Central to the logger is an ATtiny24 mated with an AT45DB161D 16Mbit flash IC
and multiple controllers can be stacked on top of each other
This breakout board for Allegro's A4988 microstepping bipolar stepper motor driver features adjustable current limiting
The SCD40 uses Sensirion\'s PASens® photoacoustic measurement system that combines narrow-band IR light and a microphone inside the sensing package capable of detecting concentrations from 0 to 40000 ppm with high accuracy over 400-2000 ppm ±(50 ppm+5% )
this line is used to control the transmission mode of the RS-485 transceiver
