Omega ADC Expansion Board

Onion Omega ADC Expansion Board plugs into the omega expansion, power, or Arduino docks through the 30-pin expansion header. This ADC expansion board includes 2 analog and 1 digital grove connectors. The OM-E-ADC board is based on TI's ADS115 4-channel 16-bit delta-sigma Analog-to-Digital Converter (ADC). This ADC expansion is stackable, and each omega2/dock will support up to 2 stacked ADC expansion boards with 8-channels in total. The omega ADC board is available with a tiny switch included on the side of the ADC expansion. This switch allows selecting the I²C address of each ADC between 0 x 48 and 0 x 49.
