Light-to-Frequency mikroBUS Module, TSL230RD (LightHz click) US$17.90

MIKROE-990
Light-to-Frequency mikroBUS Module, TSL230RD (LightHz click)


  • Temperature compensation for the ultraviolet-to-visible light range of 320 to 700 nm and respond over the range of 320 to 1050 nm
  • All inputs and the output are TTL compatible
  • Absolute Output Frequency Tolerance of 20%
  • Programmable sensitivity and full-scale output frequency
  • LightHz Click is an accessory board in mikroBus form factor. The board features a TAOS TSL230RD 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 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 board features a voltage-selection SMD jumper which determines whether it will operate on 5V or 3.3V power supply. It is set to 3.3V by default.

    Frequency scaling and sensitivity selection of the sensor can be set by bringing the logic combination to S0 S3 lines according to sensor specification. This can be done by soldering corresponding SMD jumpers to appropriate logic voltage levels, or they can be connected to your MCU and determined by software. The board comes with SMD jumpers which are set to ON-BRD configuration of scaling and sensitivity. If you want those lines to be available to your MCU, 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. Refer to the user manual for configuration details.

    mikroBUS Click Boards Overview

    Click boards come with header pins that you must solder yourself. After that, they just plug directly into a mikroBUS socket. mikroBUS is a specially designed plug-and-play pinout standard. Newer (v7) development systems manufactured by mikroElektronika, which we carry, have mikroBUS sockets already built in.

    You also can connect Click boards to many other popular platforms via these adapters:

    In addition, it is royalty-free to add mikroBUS to your own designs. Visit the mikroBUS Category to see the full line of Click boards.
