مبدل منطقی 5 به 3.3 ولت لاجیک کانورتر - Logic Level Converter 5V to 3.3V
Description
This is a breakout board for the MAX485 RS-485 transceiver IC, which will convert a UART serial stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 10Mbps. This board requires a very low amount of power and can operate from a single +3.3VDC supply.
This breakout board includes the MAX 485 RS-485 transceiver, filter capacitor, and other components shown on the schematic. We’ve broken out the RS-485 output to three different connections: (1) an RJ-45 connector, (2) a 3-pin 3.55mm screw terminal, and (3) a 3-pin 0.1" pitch header; none of these output connectors come populated.

سید علیرضا عبدالاهیان | بیش از 4 سال قبل با سلام.
تو دیتا شیت این تراشه ولتاژ رو حداکثر 3.6 ولت گفته و هم چنین گفته که بیشتر از این ولتاژ به تراشه آسیب میزنه. اما شما نوشتید ولتاژ پیشنهادی3 تا 5 ولت هست. در ماژول تقسیم ولتاژ زدید؟؟ الان بهترین ولتاژ پیشنهادی برای تغذیه ماژول چقدره؟-
ادمین | بیش از 4 سال قبل سلام، همان گونه که در توضیحات هم آمده است ولتاژ کاری +3.3 ولت است.
