Original question:

PGA450-Q1: PGA450 or PGA460?

PGA450-Q1: A 3D localization system using one transmitter and 3 receivers

Part Number: PGA450-Q1
Other Parts Discussed in Thread: PGA460, BOOSTXL-PGA460, PGA460-Q1

Hello,

I am looking to make a 3D localization system using one transmitting transducer and 3 recieving transducers, measuring the time of flight from the sender to each receiver to find a distance for each. I have been looking for a way to control the transducers and communicate with an arduino, the PGA460 appears to be my best option.

I was hoping I may be able to use the BOOSTXL-PGA460 for this project.

However, I am uncertain of how to go about converting the BOOSTXL-PGA460 board to use with my 4 transducer set-up. Would this conversion even be possible or will I need to build a control board from scratch to meet this method?

    Hi Andrew,

    You can definitely repurpose part of the BOOSTXL-PGA460 hardware, but you will need some additional components to achieve a single transmitter, multi-receiver solution. Currently, we have only prototyped this type of solution using a half-bridge driver. You can read more about transducer multiplexing using the PGA460 here:

    PGA460-Q1 Multiplexing in Half-Bridge Driver Mode for Mono-static or Bi-static Transducers ( https://e2e.ti.com/support/sensors/f/1023/t/603257 )

    Let me know if you have any additional questions after reading the article.
