This board is pretty simple.  Just follow typical assembly practices.<br>
Solder from lowest to the board to tallest components last.<br>
Hopefully, you can find some of the parts in your electronics junk drawer stash.<br>
The only reason for five possible power inputs is to match up with whatever is easiest for you use from a power input source.<br>
For example, the usb connections exist to support your typical cell phone charger or any other USB power source.  (which is always 5V).<br>
Or you may have an old power brick that has a round terminal barrel connector.  <br><br>
The voltage values of the referenced capacitors can be changed.  You can always use a higher voltage capacitor in place of the noted voltage.<br>
Additionally, you may be able to use a lower voltage than what is noted. <br>
i.e.  C3 and C4 are on the power input side of the voltage regulator. <br> If you know FOR SURE that you will never use a voltage over 5V for an input, then these capacitors can be any value above 7.5V and will be just fine.  But, if you forget and apply 12V, the caps will let out their magic smoke.<br>
Likewise, capacitors C1, C5 and C6 are after the voltage regulator and will never see a voltage above 3.3V.  Therefore, any voltage rating above 5V should be safe.<br><br>
All this to say is that you can often find a lot of the parts you need for a low voltage board like this in your stash or salvage from other boards.<br><br>


== Errata ==
The ESPixel Pops is a pretty easy build. The real trick is deciding how you plan to power your pixels as that will affect what you do with the board wiring.<br>
[[Image:Popsomatic_back.jpg|right|small]]
 
The initial board run has one small error.<br><br>
Depending on your power source, this determines if you should install the 5V regulator or just put a jumper in its place as noted on the the board.
'''This error has been fixed with the ver 1.1 board.''' (This version number is noted on the back of the board)<br><br>
 
There is an unwanted trace on the back of the board that connects the right most pin '''(as viewed from the TOP) '''of part C5 to the ground backplane that covers the bottom of the board.<br>
The board has a main voltage regulator that provides 3.3V of power to run the ESP8266 module. <br> This module does not care if you are running 5V or 12V pixels.  So, you can connect 5V or 12V to the board.
This unwanted trace should have been placed on the left most pin of C5<br>
All boards sent out, have had this unwanted trace scraped off the board. <br>
So, the end user doesn't need to do anything to fix this error.<br><br>


The board has a place for a second voltage regulatorThis is to accommodate 12V pixels.
Due to this error, the capacitor for C5 must be mounted using the middle and right most holes onlyThe left most hole is not connected to anything.<br>
<br>  
'''This restriction has been removed with the ver1.1 board'''
This is location IC1 on the board.  This is a spot for either a 5V regulator or a wire jumper.<br>
<br>
<br>
'''To summarize the population of the voltage regulators and ICs:'''<br>
This may cause a problem if your C5 capacitor has 5mm spaced leadsIn this case, you would either bend the leads to fit the more narrow spacing,<br>
The pard labeled: U1 is always installed.<br>
or you can insert the left most pin through the hole and then bend if over to connect to the middle hole.<br>
The part labeled: Q1 is always installed.<br>
In other words, part C5 must have pins touching the middle and right holesAgain, all references are from the top view of the board.
The part labeled: IC1 is installed if you are running 12V Pixel strings<br>
The part labeled: IC1 is NOT installed if you are running 5V Pixel strings AND you must place a jumper in its place as noted on the board.<br><br>

'''A Key Point Regarding Power'''<br>
The power supply you use must match the voltage requirement of your pixels.<br>
So, if you run 5V pixels, you must have a 5V PSSame is true for 12V pixels.<br>
If you accidentally use a 12V power supply on 5V pixels, you will damage your pixels, perhaps to the extent of destroying the entire string.
 
 
 
Along the bottom of the board are 5 connection points. (as viewed from the top...)<br>
The two on the left are for input power.<br>
The three on the right are for pixel connection.<br>
 
You can either solder on a terminal block or directly solder your wires to the board, or do a mix !<br>
The Terminal block has 3.81mm hole spacing. (The more common 5mm terminal blocks would have made the board too wide)<br>
 
One thing you have to decide is if you will power your pixels through the ESPixel Stick or directly to the Pixel string. (sometimes referenced as "power injection")<br>
It is possible to use the ESPixel Pops as an interface for just the data and run power to the pixels separately.<br>
This is a decision of personal preference and the fact the PCB traces can only handle so much power.<br>
Trial and error is your best approach.<br>
 
== Programming the ESP-01 Module ==
 
The heart and soul of the pixel stick variants is the firmware that runs on the the ESP-01 module.
Work has been done to consolidate to one common set of code.
 
Shelby Merrick is the keeper (and key cook & bottle washer) of this code.
He keeps the current release of code on his github page.
You can find that here: [https://github.com/forkineye/ESPixelStick/releases Pixel Stick Software]
 
As of 10/30/2017, the current release was version: '''3.0'''
 
For Shelby's v3.0 release, there is a Java Flash Tool that you run, enter your SSID and PSK for your wireless network, Pixel, the correct COM port and Upload.
 
'''Here is a posting by PCpackrat that describes his experience: NOTE:  the most current info is at the github webpage noted below...'''<br><br>
this can also be found at this DIYC posting #122 in this thread: [http://doityourselfchristmas.com/forums/showthread.php?40311-ESPixel-GECE-Info-Thread  Info Thread]
 
''The firmware is here: https://github.com/forkineye/ESPixelStick
 
Read through the README.md dont skim like I did. There is a part (gulp) that requires java to 'zip' up the web site information. I just did that part in linux and then copied the files into the data/www folder in the ESPixelStick folder.
 
Install the prerequisites in README.md
 
Pay careful attention to the Arduino for ESP8288 version (2.40-rc1). You will have to choose this branch for download.
 
My short and dirty TL;DR and things I missed:
 
Modify ssid and passphrase at the top of ESPixelStick.ino
 
Under Tools:
Choose your board as Generic ESP8266 Module
Flash Size should be 1M (128K SPIFFS)
CPU Frequency 160 MHz
Upload Speed 115200
 
Power the unit with the button pressed
 
Upload the firmware
 
Remove power from the unit and replug again with the button pressed.
 
Go to Tools and then ESP8266 Sketch data upload (serial monitor has to be closed for this)

What is the Pops-O-Matic ESP Programmer ?

The Pops-O-Matic is a dedicated programming board for the popular ESP-01 module.
This board was inspired from two articles on allaboutcircuits.com. Specifically:
Voltage Regulator
ESP Flashing Circuit
This programming board supplies both the regulated power and the programming interface for the ESP-01 module.
It specifically isolates the ESP-01 from any of the positive power that may be supplied by your serial-to-TTL programmer.
Only Ground, Transmit, and Receive are connected from the external serial-to-TTL programmer to the Pops-O-Matic. (with the assumption you hook it up properly)
The purpose of this is twofold.
1. To protect the ESP-01 module from voltages over 3.3V. (Many TTL programmers are normally run at 5V)
2. To provide the ESP-01 with well regulated and steady power during the programming sequence.

Pops-O-Matic Overview

The Pop-O-Matic is designed to be flexible in assembly and use.
It can take a wide variation of power input voltages (5V-16V) and can support up to 5 different power connections.
The board is designed to use any of the following for a power input connection types:
1. 5mm Terminal Block
2. 3.5mm Terminal Block
3. Micro USB
4. Mini USB
5. Barrel Terminal Jack

The board has a power ON/OFF switch with a power ON LED indicator.

NOTE:
Input power should be at least 400ma.

The two most popular models are known as the FT232RL and CP2102.
The FT232RL by FTDI was the defacto-standard until they released a code version that would brick peoples PC's in an effort to combat Chinese clones.
This angered a lot of the Maker community. The CP2102 then arose as a competitor to FTDI.
Both of these programmers are available all over the internet, ebay and aliexpress.
You can also order one off of TAYDA as noted.

Construction Information

This board is pretty simple. Just follow typical assembly practices.
Solder from lowest to the board to tallest components last.

The initial board run has one small error.

This error has been fixed with the ver 1.1 board. (This version number is noted on the back of the board)

There is an unwanted trace on the back of the board that connects the right most pin (as viewed from the TOP) of part C5 to the ground backplane that covers the bottom of the board.
This unwanted trace should have been placed on the left most pin of C5.
All boards sent out, have had this unwanted trace scraped off the board.
So, the end user doesn't need to do anything to fix this error.

Due to this error, the capacitor for C5 must be mounted using the middle and right most holes only. The left most hole is not connected to anything.
This restriction has been removed with the ver1.1 board
This may cause a problem if your C5 capacitor has 5mm spaced leads. In this case, you would either bend the leads to fit the more narrow spacing,
or you can insert the left most pin through the hole and then bend if over to connect to the middle hole.
In other words, part C5 must have pins touching the middle and right holes. Again, all references are from the top view of the board.
