This module enables the conversion of logic levels between two signals. It converts a signal with a logic "1" at 5 V into a signal with a logic "1" at 3.3 V. This is useful to enable communication between two devices, one of which operates at 5 V and the other at 3.3 V. https://elecena.pl/product/25933538/333017-developer-boards-ttl-logic-level-converter-4-channels-txb010 2024-05-24 https://elecena.pl/product/25933538/333017-developer-boards-ttl-logic-level-converter-4-channels-txb010 2025-04-07
