ESPixelStick V2 Group Buy

This post has been updated for the first round of 2017 Group Buys. This buy will last 3 weeks, ending on February 10th and I expect to start shipping boards out the week of March 13th. All orders for the group buy must be placed and paid for by midnight on 2/12. The cost will be the same as the last group buy, and I’ll be using Google Forms with PayPal invoicing again for order placements. Details are all below!

The ESPixelStick is an E1.31 WiFi pixel controller built around the ESP8266 in an Arduino environment. An overview of the ESPixelStick V1 is available here, and I’ll expand on the V2 changes in just a bit. The ESPixelStick supports up to four universes of WS2811 pixels on a single output, or up to 63 GECE Pixels. The firmware is open source, available here. Once connected to your WiFi network, further configuration can be done via the embedded web server. The controller is small enough to fit inside 1″ thin wall PVC, allowing you to embed the controller next to your element eliminating issues of long pixel runs. The ESPixelStick V2 is provided in kit form, with all SMD components pre-soldered. Please feel free to address any questions or concerns in this thread, thank you!

V2 Updates
1) Power supply section is completely different. It has an on board buck converter for 5V-24V DC input that will run 100% duty cycle at 5V and the 3.3V LDO is a different part as well. No longer have to worry about voltage configuration.
2) Mounting hole sized for a #8 screw to easily mount in CG cases.
3) Fixed the issue with using 3.3v programmers.
4) Fixed a potential issue that could cause the ESP module to hang if a watchdog reset occurred or the module rebooted.
5) All passives are SMD now. Only components left to solder are headers and buttons.

How to Participate
I’m doing this a little different than most group buys. To ease logistics and keep orders / shipping straight, I’ve created a Google Form for participants to fill out. I will periodically review submissions, issue invoices via PayPal and update this thread with participants. Please allow a day for me to invoice you. If there are any questions or concerns, please feel free to post about them in this thread. If you have not received a PayPal invoice from me by 12PM EST on 8/15, CONTACT ME ASAP.
