If it is a little bigger to incorporate a bigger chip antenna and some GPIO pins, it is going to be very useful for a lot of IoT projects!!

- pegor 11mo agoDefinitely would be more functional with more of the GPIOs exposed.
- forsalebypwner 11mo agoIf you want an ESP32 dev board with GPIOs exposed there are dozens (or hundreds, maybe thousands) of other options out there. It makes sense not to expose them when you're going for the smallest possible footprint.
- stavros 11mo agoI don't know, I see enough space for four GPIOs there. Not holes, obviously, but pads should be very workable.
- imtringued 11mo agoIt could be even smaller without that USB C port and have more GPIO pads.
- PunchyHamster 11mo agothere is plenty of those already and not all too hard to make yourself, see LilyGo T01-C3 Its of format of original ESP8 so you get serial + 3 IO pins
- margalabargala 11mo agoThe XIAO series of ESP32s is exactly that. They are 4x the size though, almost exactly double in both length and width. https://wiki.seeedstudio.com/XIAO_ESP32C3_Getting_Started/ https://wiki.seeedstudio.com/XIAO_ESP32C3_Getting_Started/
- sho_hn 11mo agoThese are quite lovely. Ceramic SMD antennas are awesome.
- dotancohen 11mo agoIt's also got 15 times as many GPIO pins as the board in the fine article. And this PCBA will be smaller than the battery in most applications anyway.
- margalabargala 11mo agoIt only has 14 pins, 3 of which are 5v, 3.3v, and ground, so slight exaggeration :-) point taken though
- lelanthran 11mo agoThese are nifty. I've used them in production, but if you want to make used of the charger it's difficult.
- venusenvy47 11mo agoCan anyone suggest a small module that supports 5 GHz WiFi?
