== Meetings

'''2018-10-04'''

Met with Shivang Dave and Carlos Santago from plenoptika

Basic requirements:

* Form factor about 0.4" x 0.8" x .04"
* DC constant-current laser drive 0-80mA
* CMOS 3.3V(?) logic enable (normally off, logic '1' to enable)
* 3.3V power supply

Manufacturing in Spain, need to check about component technology preferences
