I am surprised that the level translator works with the 2N7002 FET. The datasheet shows a typical gate threshold voltage of 2.1V, so at 1.8V it is barely open.</p> <p><img src="/resized-image/__size/1280x720/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-07f2fdf5-e7a2-4de2-bf00-7248730314a7/pastedimage1672086476655v1.png" alt=" " /></p> <p>And I remember, I did the same and no luck with this part. I had to use a part with a lower threshold voltage.</p><img src="https://community.element14.com/aggbug?PostID=24977&AppID=145&AppType=Weblog&ContentType=0" width="1" height="1">RE: Tiny GNSS Module Interfacing With Microcontrollershttps://community.element14.com/products/arduino/b/blog/posts/tiny-gnss-module-interfacing-with-microcontrollersMon, 26 Dec 2022 19:02:09 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:07f2fdf5-e7a2-4de2-bf00-7248730314a7dougw2<p>It sounds like you could run it directly with a Pi Pico running at 1.8 v.</p><img src="https://community.element14.com/aggbug?PostID=24977&AppID=145&AppType=Weblog&ContentType=0" width="1" height="1">RE: Tiny GNSS Module Interfacing With Microcontrollershttps://community.element14.com/products/arduino/b/blog/posts/tiny-gnss-module-interfacing-with-microcontrollersMon, 26 Dec 2022 15:44:05 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:07f2fdf5-e7a2-4de2-bf00-7248730314a7shabaz1<p>The circuit diagram doesn&#39;t make much sense, it appears to be two different designs mashed together? I don&#39;t get what U5 (buck regulator) is needed for, since there is already 1.8V from U3. Also, what is the USB-UART chip (U4) used for, since it seems to be connected to header pins that go nowhere from what I can tell.</p><img src="https://community.element14.com/aggbug?PostID=24977&AppID=145&AppType=Weblog&ContentType=0" width="1" height="1">
