    UART logic level

    I choosed it primarily because it was recommended in the datasheet of the GPS. The pcb will be 6/8 layers (at least 2 of them will be ground planes).

    UART logic level

    I found these two: https://www.digikey.bg/en/products/detail/nexperia-usa-inc/74LVC2T45GT-115/2530598 https://store.comet.bg/Catalogue/Product/46370/ - both are bi-directional and are 1.8 to 3.3V

    UART logic level

    I am attaching the datasheet of the MCU used in the Teensy 4.1, I am not sure about 4.3.2.1 General purpose I/O AC parameters in the datasheet. (Page 39 & 40) - the file is too big so here is link to digikey https://www.nxp.com/docs/en/nxp/data-sheets/IMXRT1060CEC.pdf

    UART logic level

    I need a duplex communication as the moduel also has GSM and I need to send AT commands to it, I will attach the datasheet again. Also is it possible to delete the older thread?

    UART logic level

    I have a gps module which uses uart for connection to the mcu and I wany to use it with the teensy 4.1. The problem here is that the uart of the gps is 1.8v and I am not sure if the teensy will be able to read the data from the gps?

    URGENT Quecetel EG915NEUAP-N06-SGNSA and Teensy 4.1

    I need to use this Quecetel module for a project with the teensy 4.1 but I do not know whether they will work together. The UART logic voltage of the GNSS+GSM module is 1.8V and I want to use micropython is it possible or should I use a voltage translator?
