![]() ![]() It has a 1.8V linear regulator along with proper 16ch level shifter.Īt best - get a better programmer that actually does support 1.8V chips. Basically you are risking killing PWM controller or even a CPU along with SPI flash.Īt bare minimum you should use a proper 1.8V adapter board like this: Some boards may have N-ch FETs along the way that'll prevent further damage, but most lower-end boards don't. Not even a ghetto solution of current-limiting resistors, which is still unreliable but at least it'll keep the SPI flash alive.ģ) hooking up this abomination to SPI header may also cause issues, since flash isn't the only thing on 1.8VSB rail. Combine that with 1.8V flash and at best you get a corrupt firmware, and at worst - you'll need a new chipĢ) It's so cheap that it even has absolutely nothing on data lines. All have 3.3V VCC_SPI, but some also have 5V logic levels. Crossflashing experiments are cool and all, but there is one thing you should NOT do under any circumstances, and that's use this piece of garbage CH341A within a 10-mile radius of any 1.8V SPI flash.ġ) There are many equally shitty variations of this programmer.
