The Development Kit based on ESP8266, integrates GPIO, PWM, IIC, 1-Wire
and ADC all in one board. Power your development in the fastest way
combine with NodeMCU Firmware! R2 version had CP2102 USB-TTL instead,
larger current support, slim board can put on breadboard.
NO need to install driver for CH341 (replaced by CP2102), and NO need to
flash firmware when you get it and use on first time. This is different
with version R1.
To flash R2, please see the update on Nodemcu wiki page.
High quality USB cable is needed for this board to give high current supply, otherwise your board won’t be recognized.
hardware documentation for the board can be found on nodemcu-devkit
repo, including schematics and PCB layout designed with Altium Designer. Features
- Wi-Fi Module – ESP-12E module similar to ESP-12 module but with 6 extra GPIOs.
- USB – micro USB port for power, programming and debugging
- Headers – 2x 2.54mm 15-pin header with access to GPIOs, SPI, UART, ADC, and power pins
- Misc – Reset and Flash buttons
- Power – 5V via micro USB port
- Dimensions – 49 x 24.5 x 13mm
can find the firmware source code and documentation on Github, as well
as nodemcu-flasher, a Windows only tools to flash the firmware to a
module. There’s also a separate tool called esptool that will let you
flash nodemcu from Linux. In case you find the documentation is all over
the place, you might want to checkout NodeMCU video tutorial below.
is the official website for the project, but you’ll find more
information on Github. You can also get answers to your questions on
their BBS or ESP8622 community forums.Wiki & External linksCP210x USB to UART Bridge VCP Drivers
