                wemos usb host 
              
          
    Today I connected my USB host board (see "hardware" section below) to my Wemos 1D device.
It receives data from an outdoor "weather station receiver" and prints in to serial console in Arduino IDE.
Hardware:


"ELV Wetterdaten Empfänger" (https://www.elv.at/usb-wetterdaten-empfaenger-usb-wde1-komplettbausatz-1.html)
USB Host Mini (http://www.hobbytronics.co.uk/usb-host-mini) preinstalled with "Serial Driver for FTDI, CP210X, PL2303"
Wemos 1D (https://www.wemos.cc/product/d1-mini-pro.html)
