I'm confused about ST nomenclature for VL53L7CH

HenryTheGreat · ‎2025-09-03

I want to try the VL53L7CH, I purchased the SATEL-VL53L7 and the x-nucleo-53l7A1. When I look at the boards on the SATEL-VL53L7 they look identical. But the description says it supports both the CX and CH models. Can someone clear this up?

So it looks like the chip on those boards is a "special" which can behave as either the CX or the CH version?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
