LightHz Click Board™
The MikroE LightHz Click Board™ is an easy and compact solution to add light-to-frequency conversion functionality to your project. This add-on board features a TSL230BR programmable light-to-frequency converter, which provides high-resolution conversion of light intensity to frequency without requiring external components. All inputs and the output are TTL compatible, and allows for direct two-way communication with a microcontroller for programming and output interface. The output can be either a pulse train or a square wave (50% duty cycle) with frequency directly proportional to light intensity. It has programmable sensitivity and full-scale output frequency. The device sensitivity is selectable between Power Down, 1x, 10x and 100x. The full-scale output frequency can be scaled by one of four preset values: 1, 2, 10 and 100. The device sensitivity and frequency scaling can be determined by the microcontroller, or selected using available SMD jumpers. It is designed to operate on 3.3V by default, however, the user can select 5V power supply through a voltage-selection SMD jumper.

IC/Module: TSL230BR Programmable Light-To-Frequency Converter
TSL230BR is a light-to-frequency converter that combines a configurable silicon photodiode and a current-to-frequency converter. The output can be either a pulse train or a square wave with frequency directly proportional to light intensity. It has programmable sensitivity and full-scale output frequency.
According to the sensor specification, the frequency scaling and sensitivity selection of the LightHz Click can be set by bringing the logic combination to S0-S3 lines. This can be done by soldering corresponding SMD jumpers to appropriate logic voltage levels, or they can be connected to the microcontroller and determined by software. The board comes with SMD jumpers which are set to ON-BRD configuration of scaling and sensitivity. If the user want S0-S3 lines to be available to the microcontroller, just resolder the SMD jumpers to the MCU position. Default on-board configuration for scaling is (S2, S3) = (H, H), which represents a value of 100, and for sensitivity is (S0, S1) = (H, H), which represents 100x.
