TTL Signal System Conversion Module RS422 Full Duplex Bidirectional Switch RS 422 To TTL Module SCM MAX490

Πολύ καλό με μεγάλη ακρίβεια. Και με προέκταση καλωδίου

Πρέπει να τοποθετηθεί για να ξέρω εάν είναι σωστό.

Dear Joom Team The TCM2208 drivers cannot be used because the connections have been soldered on incorrectly (see photo). Thus, the Vref voltage cannot be set on the driver and the heatsink is in the wrong place. You can see how it should be on the 3rd photo (Image-2.jpeg). Send me 4 new TCM2208 drivers that are correct. With kind regards Heinz Leukel

top product , I am impressed with the product +i recommend use 8 Ohm speakers or two 4 Ohm speakers per channel in series (not tested) +I tested 2 speakers of 20w plus 2 speakers of 30w plus 2 tweeters all in parallel and all 4 Ohm , still normal, but not enough amperes (I tested with a 19V and 3A supply) +I come back to edit the review after testing with 24V 6A

Works well. Warning: for the adjustments you must start by adjusting the low threshold and then only after, the high threshold. If you want to modify the high threshold again, you must first go through the detection of the low threshold. Otherwise, we don't get the desired result...

The output voltage does not adjust regardless of what input voltage I give it, it basically acts as a bypass not as a buck converter, I have bought from this seller before and I am satisfied with the quality of his products but for some reason this product does not work
