Video Description
New Second channel: https://www.youtube.com/channel/UCviMJUlUlrplcVI2SszNbfw The CH341a Mini Programmer is a super cheap BIOS chip programmer that I've wanted to cover for a while now, but there's a problem with it. While the chip socket is powered at the correct 3.3v, the _data lines_ are pulled up to 5v, which is way too hot. Modifications to run the controller chip off of the 3.3v rail are fairly straight forward, and fix the problem completely. Shout out to Voltlog for their video on this, which I followed to make mine: https://www.youtube.com/watch?v=-ln3VIZKKaE And the One Transistor article Voltlog referenced: https://www.onetransistor.eu/2017/08/ch341a-mini-programmer-schematic.html Join the Discord right here: https://discord.gg/BDV4hTc Support the channel directly at: https://patreon.com/adamantit Follow us on Twitter at: https://twitter.com/adamantit Check out our Instagram at: https://www.instagram.com/adamant.it
