First version of a Arduino Nano HAT to connect multiple photometer cells. It works BUT.

Problems:

• jst connectors too close together

tt_nano_HAT_b2

Kitspace page

Second version of the Arduino Nano HAT. It looks better and works BUT.

Problems:

• connections/annotation screwed up.

(I'll never learn)

opt101_module

Kitspace page

PCB that fits the opt101 and a potentiometer to set the sensitivity of the sensor. Works great and fits perfectly into the housing of the measurement cells.
