## Questions & Answers

**Q: When i connect it to the usb port on my windows 10 computer, i do not get a new com port. anyone else have this issue?**
A: As others have suggested, installing the serial interface driver is necessary.

The driver you are looking for is the CP2102 driver. A google search for CP2102 driver should bring you to it. The first link that appears, at silabs.com. it's the "CP210X USB to UART Bridge VCP" driver. This is required for windows to create the virtual com port (VCP). Once installed, you will see a COM port assigned in Device Manager under Ports and Communications section. This will be the COM port you select in Arduino IDE or whatever flasher you use, such as esptool.

Other details:
- A data cable is necessary (not just a charging cable).
- It does NOT show up or appear as "another memory drive" to Windows. You will only see the COM port, because the only part of the board directly exposed to Windows is the serial interface chip (CP2102).

**Q: do i need to use step down converter or can i connect 12v right to vin?**
A: Hello, the working voltage of the ESP8266 module is 3.3v to 5V, you need to use a voltage regulator to stabilize the voltage to 5V.

**Q: can not upload a sketch with arduino ide ?**
A: Assuming you’ve got the correct USB-to-Serial drivers installed already, you’ll then need to add the board profile for this device.  It’s a JSON document which you can easily find by doing an internet search for “esp8266 arduino board profile”.  Add the URL to that json doc in the Arduino IDE preferences -> Additional boards manager URLs.  Then, bring up the Board Manager (Tools -> Board -> Board Manager…) and search for esp8266.  Select that result and click Install.  Now you can select the correct board profile under Tools -> Board -> esp8266 -> NodeMCU 1.0 (ESP-12E Module).  Finally, select the correct port.  For example, on the Mac, you’d select Tools -> Port -> /dev/cu.SLAB_USBtoUART

**Q: Is a0 adc analog pin on this board 3.3v compatible, or is it only 1v compatible?  in other words, does it scale 3.3v to 1v for the 8266 native chip?**
A: The nodemcu boards include a voltage divider to scale the 3.3v to 1v.
