BG557252118 with 1kW per m2 and 20% efficiency, the theoretical max power is 0.28m X 0.28m X 1000 X 0.2 = 15.7W.

BG557252118 for clarity these are the RF frequencies - not processor speed. some frequencies are not permitted in some countries

BG557252118 there needs to be a definite answer to this question. digging around the internet turns up the GitHub repo linked below. this gives instruction how to set up platformIO and provide a GD32v SDK and Arduino interface. no RTOS, so no easy path for providing an interpreted environment. So unless TTGO have hacked something together (and hidden it very well) I would say no uP support.

BG557252118 I don't know if you got this working, but for reference, I got mine running using Lobo. for some reason I can't submit the URL, but just Google Lobo esp32. the screen works out the box, and it makes a lovely board once unshackled from the limitations of Arduino

AndrewWilson I would be surprised if it is tiny being an oled and will be dependent on illumination level - more white, more power. It would be easy enough to measure through by putting a multimeter in circuit and testing with all black, all white and various typical uses. always worth using the blank function in your library (certainly the micropython library has it to minimise power
