Eye-spy (replacement part)

Purchase individual Eye-Spys for your Pioreactor or other projects! This is a high resolution, high amplification, ~900nm sensor over I2C. The board is STEMMA QT compatible. 

Left: i2c address 0x49 (used as REF in the Pioreactor)

Right: i2c address 0x4a (used as 90 or 135 in the Pioreactor)

However, either board can be solder-bridged to create any address 0x48, 0x49, 0x4a, 0x4b.
