DESCRIPTION
The Omega ADC Expansion will bring a new world – the analogue world – directly to your Omega2 projects. Based on the ADS1115 analogue-to-digital converter chip, this Expansion provides 4 analogue input channels, each with 16 bits of precision at a maximum of 860 samples per second, and communicates with your Omega using I2C.
With this Expansion, your Omega will be able to read and interpret analogue signals! This opens the door to a whole bunch of sensors. Directly connect up to 4 analogue signals to the female header on the board and safely sample analogue voltages from -6V to +6V. There are also power and ground headers for each analogue input, providing an easy way to power your sensors.
Onion are huge fans of the Grove family of sensors, actuators, and controllers, so they’ve included 3 Grove connectors right on the ADC Expansion. Two connectors are analogue, and the third is digital I2C.
A nice bonus about the ADC Expansion is that it’s stackable, each Omega2 can support up to 2 stacked ADC Expansions, giving you 8 analogue input channels in total. The switch on the side lets you change the I2C address (between 0x48 and 0x49).
