Works as expected but need experience
These are great for adding Wi-Fi to 3D printers (using ESP3D firmware) but can be difficult to program without experience and proper software/programmer.They come unprogrammed but can be used for many types of projects.

If you want to order these you should re-think that idea!!!
OK, I ordered these for an ESP-NOW (network required) project and I've really, really been let down.When I received them I figured one or two might be iffy so I set all of them aside until I actually needed them. Well that time has arrived and man am I disappointed!!!Here's the break down:3 units were completely dead.5 units worked as cpu only, there was no network connection at all.2 units worked as expected except for the memory size problem (1 meg not the 4 meg advertised)Because I'm naive I wasn't expecting this level of problems.My stand is that no one should buy from this company and Amazon should remove this vendor from their system.

These are advertised as 4MB flash, that is a LIE, they are 1MB , at least the ones i received are
