Three ESP32 boards but they are not equal!

All running esp-idf hello world
DevKit-C: 41mA@5v or [email protected] (regulator bypassed)
Lolin32-Lite: 29mA@5v or [email protected] (regulator bypassed)
TTGO: 34mA@5v or [email protected] (regulator bypassed)
ESP32 - Silicon Revision
DevKit-C reports Rev0
Lolin32-Lite and TTGO report Rev1
Battery support
DevKit-C is missing any LiPo support. Both the TTGO and Lolin32-Lite have connectors and support USB charging. Great!
Size
DevKit-C is the largest at 58mm x 30mm
Lolin32-Lite is much smaller at 50mm x 25mm
TTGO is just slightly longer and thinner at 51mm x 23mm
Conclusion
I really like the Lolin32-Lite. It’s the cheapest and the build quality is fantastic. The power consumption is very low too.
Now I’m just waiting to see what the Olimex ESP32-Pro is like!
