What is it?

This is a PIXYEXPERT (named because it drives neopixel leds)that makes interface of esp8266 and WS2812B in easy way .. this board is easy to solder since it consists of all THT components except the esp8266 module and ams1117.. 

Why did you make it?

The reason to design such board is to integrate THT & SMD components for a solder teach with some  IOT and Fun. this kit is build as engineer friendly which brings colorful life to the engineer. Also this kit will teach the engineer

1) how to program the esp8266MOD without any usb or  Dev board like arduino or nodemcu

2) The bare minimum configuration for the ESP8266MOD so that he could develop IOT projects with ESP8266MOD rather than the Nodemcu or any other development board.

3) how to code the ws2812b leds with different designs and patterns. for example: The ws2812fx library.

Esp8266MOD or ESP8266 12F MODULE check pcbway gift shop


ESP 8266 - 12 F is the enhanced version of ESP 8266 - 12.

External power lines, quadruple board boards, better signaling exports.Enhanced version is fully compatible with the previous firmware. and on the basis of the pin in the ESP-12, the addition of six IO port and SPI port.


Model: ESP8266-12 F

Frequency range: 2.4GHz-2.5GHz

Operating voltage: 3.0 - 3.6V

Wireless standards: 802.11 b / g / n

Working Current: Average: 80mA

Operating temperature: -40 ° - 125 °


1.Due to the hand measurement, there have size error about 1-2cm or more.

2.Please be reminded that due to lighting effects and monitor's brightness/contrast settings etc, the color tone of the photo and the actual item could be slightly different.      

Capacitor : 10uF and 100uF

resistor : 10k

AMS1117 3.3v Voltage regulator

This power supply module is based on the AMS1117 3.3V regulator. It is capable of regulating a wide range of input voltage (4.0 to 12V) down to a fixed 3.3V output at up to 1A (Vin = 4.5V). Standard 0.1″ header pins provide a means of connecting to its input and output terminals.

These header pins have also been conveniently placed so that the module can be inserted face down into standard

Note: Do not exceed absolute maximum input voltage (12.5V) or output current. Exceeding maximum specifications can result in permanent damage to this module or any connected devices.

Features :

  • Onboard AMS1117 chip.
  • Onboard power indicator to indicate power is turned on: Red LED.
  • Output voltage interface, connection to facilitate the experimental.
  • Specially designed two pin mounting holes, can be directly fixed on the whole expansion board for experiments.
  • Small Compact Size, 4Pin Type, Breadboard Friendly.
  • 2P single row pin input and output for easy connection
  • Dual-panel design, the layout is nice
  •  components that are required to build the project

    Hope you enjoyed making the project . you could get this project as a kit on my tindie store. (there is a delay faced in the stock fillup due to the shipments service in pandemic)

    you could order the pcbs for the project  from

    If you purchase the kit it would be helpful to me and i appreciate that because it will help me get a cup of coffee or some components for my future projects.. and i always send gifts to my supporters as a token of thanks..

    do follow me as i add updates about the project and relevant links in the comment of each projects.

    stay safe stay tuned
