SALE! BUY THIS DEVELOPMENT BOARD AT THE INTRODUCTORY PRICE OF $12.99!

This is the NON-BATTERY VERSION of the NodeMCU Wireless Development Board found HERE. This system is compatible with the Arduino IDE programming environment and libraries

Due to an error at the fabrication plant, these PCBs are missing the slots to connect the battery holder. I decided to replace the 5V boost/buck regulator with a lower-cost 5V linear regulator and sell this as a lower-priced option to the original board. This version DOES COME with a 9V/1A power supply with 2.1mm jack!

NOTE: This system is not PHYSICALLY compatible with any other micro-controller, or Arduino board. The shields for this system will only mount on the NodeMCU Development Board

This version of the board board CAN NOT be mounted to the dual-18650 battery holder.

The Development Evironment currently includes add-on shields such as:

• Motor Shield supporting 4 DC motors (3A per-channel PEAK) or 2 Steppers, plus (4) 5v hobby servos found HERE
• Sensor Shield with on-board Atmega328 micro-controller that supports 4 Ultrasonic Range Sensors plus 4 Passive Infra-red sensors, with a dedicated I2C port and 12-bit 4-ADC inputs HERE
• 16-port bi-directional IO Expansion Shield found HERE
• 12-Bit + 16-Bit, 8-Channel ADC Expansion Shield (currently in development);
• 16-Channel, 12-bit PWM Servo Shield (RELEASING SOON!)
• Postage-stamp sized I2C add-on sensors such as a the BME280 temp/humididy/pressure sensor, the CCS118 Air-quality testing/CO-monitoring sensor, luminosity sensors, etc

All of the boards and shields in the environment are optimized for minimum footprint with maximum feature-set.

This NON-BATTERY VERSION of the NodeMCU Development Board has the following features:

POWER

• 6-12V DC INPUT VOLTAGE Comes with 9V/1A power supply with 2.1mm barrel jack.
• On-board 5V regulator can supply up to 1.5A of output current
• On-board 3.3v regulator can supply up to 800ma of output current
• Can be powered from 2.1mm barrel jack (6-12V DC INPUT)
• Can be powered from screw-terminal connector (6.2-12V DC INPUT)
• Can be powered via microSD cable (not included)
• Battery power switch
• Reverse-polarity protection on screw terminal
• Back-feed protection for screw terminal
• Aluminum electrolytic capacitor and inline ferrite bead for power smoothing and brownout prevention
• Self-healing polyfuse for overcurrent protection
• Includes 9V/1A AC/DC power supply (USA-COMPATIBLE) with 2.1mm barrel jack

FEATURES:

• On-board MicroSD card reader
• Dedicated SPI header support NRF24L01+ 2.4Ghz radio modules (see note below)
• Tantalum capacitor for power smothing/brownout protection of SPI port
• Dedicated I2C header, supports use of small add-on sensor modules
• Pull-up resistors on I2C lines with cutable traces
• Onboard ESP8266 ESP-12E module
• All ESP8266/NodeMCU pins broken out
• Red LED connected to pin D0 - conforms to LED_BUILTIN specification in Arduino IDE
• Green power LED

NOTE2: NRF24L01 module can not be used when the Sensor Shield is installed as they share pin D4

DIMENSIONS:

• Board Outline 78.6mm x 36.6mm
• Mounting Hole Diameter 3mm
• Mounting Hole Spacing 32.5mm x 67.9mm
• Board Height - ~17mm

This board can be ordered fully-assembled or as a kit for self-assembly. All SMD components are pre-installed.

This board requires an OPTIONAL micro-USB cable for programming.
