The D1 is a WiFi capable ESP8266 based development board in the form of the Arduino UNO board format. This board is compatible with the Arduino IDE and with NodeMCU. The D1 also features an on-board switching power supply which allows you to power the board from a power supply up to 24V, 11 GPIO pins (can be used as input/output/PWM/I²C, except D0), and 1 analog input. The PWM resolution is 10bit (1MHz frequency). The integrated 5V switching power supply (1A) is followed by an 3.3V LDO to supply power for the Wifi module and the 3.3V output (power supply for sensors and shields). Please pay attention when you connect other active periphery to the I/O pins, because this is a 3.3V logic level device and higher levels on any pin will destroy it. The max. input voltage for the analog pin is 3.2V

Very good product and service
This board is a WeMoS D1 R1 which I bought so as to control a USB hub's power/switch. Initially the WeMoS was bought for educational investigation and I needed something that it had bigger flash than Arduino. The WeMoS board does it!The support pages of Universal-Solder (U-S) were very useful in getting Arduino IDE installed with the correct library. Of note: Arduino IDE is Java based and had security that blocked download of the library. Not U-S's problem, and found disable of my internet-security and getting the Java prompt to trust the download via Win10 overcame the prob.The board is robust and tolerate for output pins and power, not sure on input pins but avoid > 3.3V stuff. I asked a question of U-S and the response was quick and answered the question. Also, a following support email was sent to U-S and was professionally responded too.
