| Yeah, i agree that the ESP32 docs are good, and what you're going to be using most of the time while using these things. That wasn't what i was talking about though -- if you have a look at the datasheet for this board ( https://docs.arduino.cc/static/4260b2f8de0b7abc50d3773839dee... ), there's plenty of board-specific info in there that's useful, and also plenty of stuff that's technically duplicated from the ESP32 documentation, but harder to find if you're a noob. I can't get mad about the unnecessary layers, sorry. Using the ublox module is quite reasonable: it's smaller than any of the available modules from espressif (necessary for this form-factor), probably because they have licensed a fancy antenna design (the same one that rpi uses, i think). Using a module in general is a good idea, as it means you don't have to take on the cost and risk of doing the RF design yourself. If you buy a board using a 3rd-party module, there are probably going to be three vendors involved. Another thing i didn't mention -- as far as i know this is the first ESP32 board you can actually buy in the same form factor as the arduino nano, which is handy if you want to switch an existing project over to ESP32. In general I fail to understand why people are so salty about this. I see engineers using this kind of thing all the time, and they aren't stupid. It's perfectly fine to spend a bit more money to get something even marginally better. Yes, the relative price difference is huge, but $20 makes no difference in a lot of situations. |
