| Aug 11, 2017 at 9:30 | comment | added | dandavis | looking at the D1's schematic, the GPIOs are almost all wired straight-through to the 12F module, which would imply all 12Fs share the property. I believe it comes down to quality/die luck: the only one (of dozens) i've had that was noticeably finicky w/ 5v components was one that also froze when "overclocked" to 160. The main issues likely stem from too much heat, and a D1 probably dissipates heat better than an ESP01, commanding more volume in an enclosure if nothing else... | |
| Aug 11, 2017 at 7:30 | comment | added | Code Gorilla | @dandavis - The ESP8266 chip data sheet says that the GPIO pins only accept 3.3v max (download.arduino.org/products/UNOWIFI/…), but I know the Node Lua and Wemos D1 are 5v tolerant (well they didn't burn). I don't have a definitive list, in fact I would even stake a donut on the fact that all Wemos D1s are 5v tolerant, because there are so many different designs of the "same thing" | |
