Received the WEMOS D1 mini Pro in my physical mailbox. Great board that replaces my design of ESP8266 development board. In this integrated a USB to serial converter and an ESP8266-12 board and 5V to 3V3 converter. I wonder how much power he uses when the ESP chip is in sleep mode. I’ll measure that some time later.
Above a comparison with the size of my own designed development board. The price is very low for what you get in return: € 4.80 via aliexpress.
