• Power supply voltage: DC 5V (USB)
• Input/Output voltage: DC 3.3V
• I/O Pins: 34
• SRAM: 520KB External Flash

<b>Features:</b><br> 11 digital input / output pins, all pins with interrupt / PWM / I2C / support 1 line (except D0)<br> 1 analog input(3.2V max input)<br> Micro USB connection; Compatible with Arduino<br> 1MB Flash<br> 500mA resettable fuse<br> A Micro USB connection<br> Board Size: 3.4x2.5cm/1.34x0.98inch. <br><br> <b>Tips:</b><br> * For the pin layout, Google "Wemos mini NodeMcu". For example D5 is equivalent to GPIO 14.<br> * Solder properly. Use a LED to test if it will lit.<br> <b>Pros:</b><br> * Smaller form than the standard NodeMcu<br> * 4Mb flash memory<br> * Solid build<br> * Usb power works<br> * Works well with Micropython firmware<br> * The Nodemcu/Lua firmware also works fine<br> <b>Steps for usage:</b><br> * Download the Arduino IDE from the arduino.cc site at en/Main/Software.<br> * I found an OSX driver for the board at github.com on "adrianmihalko" 's page. You will want the files under the ch340g-ch34g-ch34x-mac-os-x-driver repository.<br> * Once both of these are installed open up the Arduino IDE.<br> * Go into the preferences and add the url as stated in the product description above (sorry can't post the url here).<br> * In the "Board Manager" search for and install the latest version of the "esp8266" generic module.<br> * Select the new "Port" added by the driver: (mine was "/dev/cu.wchusbserial14120").<br> * Set the "Reset Method" to: nodemcu.<br> * All done!<br><br> <b>You'd better to write a simple "blink" sketch and upload it to your board to see it work.</b><br> <b>The LED pin on this board is "2".</b><br><br> <b>Package Including:</b><br> 2* D1 Mini Development Board<br>
