LightHz Click is an accessory board in mikroBUS form factor. Board features TSL230BR programmable light-to-frequency converter. The output can be either a pulse train or a square wave (50% duty cycle) with frequency directly proportional to light intensity. Device sensitivity is selectable in three ranges, providing two decades of adjustment. The full-scale output frequency can be scaled by one of four preset values. Board features voltage selection SMD jumper which determines whether it will operate on 5V or 3.3V power supply.
