Hello guys,
There are 4 tiny buttons on the board, Boot, Reset, K1 and K2. Only reset button seems to function. What are the rest 3 expected to do?
I was hoping one of the buttons put the device in sleep mode or turn the lcd off. As otherwise running on battery, it lasts only 20 min before the battery goes flat.
The function of the BOOT button is to enter download mode using the ESP32C3 chip. K1 and K2 are user programmable buttons that currently have no function and require users to assign their own functions, such as entering sleep mode.
