I also want to make an air pollution meter. I read in the Firmware Flasher section that a microUSB of less than 1 meter is required for installation. I found one at home that is between 95 and 100 cm. Is this appropriate?
I would have another question, that I need to install the NodeMCU driver on my computer first, and then download the appropriate driver from the firmware flasher, which should be installed on the NodeMCU? Or exactly how is it? Maybe there is a video of the steps described on the page?
Thank you in advance.
