### How to connect four TCRT5000 to my Rasperry Pi 3

Posted:

**Sat Sep 07, 2019 9:58 pm**Hi,

I am interested in buying four of the TCRT5000 on LM393 boards . I would like to only use a Raspberry Pi 3 , but I am not sure I have enough voltage connectors for all for TCRT5000 on a single Raspberry Pi 3. What is the best solution for this?

Thanks.
