Ch341a V - 118

Most generic CH341A programmers use a passive voltage divider (two resistors) to drop the 5V data lines to 3.3V. While cheap, this method fails at high SPI speeds and cannot drive capacitive loads well.

How can you identify a genuine (or well-made) CH341A v 1.18? Look for these features: ch341a v 118

Modern laptops use 1.8V SPI flash. The v 1.18 only does 3.3V and 5V. Remove the existing 3.3V regulator. Wire in an external adjustable regulator (like the MCP1700-1802) set to 1.8V. Also change the pull-up resistors to 1.8V logic. Most generic CH341A programmers use a passive voltage
