I did drop a question there, already, but then the forum struck me like being quiet and I thought I'll try it here, too, and indeed, I got all this useful feedback.įor a free schematics tool with simulation ability, I recommend LTSpice. I have the same 38 pin version and in breadboard it leaves two set of pins to connect male to male jumper cable. The only drawback is that I cannot find the parts I need.į has a forum, that's the place to ask once you've checked out The Fritzing Parts Library Thomas ESP32-38PinWide.fzpz (40.3 KB) 3 Likes SwayamjitSahoo August 21, 2021, 4:44am 5 Please correct it It is not leaving 1 set of pins on either sides of the breadboard. Up to 8 PCF8574, IO Expansion Board can be connected to the I2C-bus, providing up to 64 I/O ports. The schemes are very illustrative and easy to read by students (exactly like MarkT noted). Overview The PCF8574 IO Expansion Board is used as a remote 8-bit I/O expander for I2C-bus. Fritzing is very easy to use: parts are on the right and you just drag and drop them and connect them on the spot. I just need to draw a couple of schemes and be done with them. I did try Eagle (I still have it installed) but its use didn't appear very straight forward to me and I don't want to invest much time in learning such an application. I have not seen a good schematic created in fritzing. Fritzing doesn't seem much better than a toy. Try Eagle or other free PCB/schematic software.Įagle gets my vote.
