I burn the bootloader & the main sketch to the raw chip prior to soldering it in. The only reason I included a FTDI connection on the board was for reading the serial output.LOL Here's my thread that explains how to "Burn your own"- http://reefcentral.com/forums/showthread.php?t=2197597

Very cool.
I had no idea those TQFP sockets existed.
I have always added a 2x3 pin header to my designs and use a USBtiny.
I'm going to have to find one of those sockets.
Breaking out the FTDI connector is always a good idea in my opinion for debugging, serial motoring, data logging, and or reprogramming.
Nice job.
Thanks,

Since he released the design files 5 days ago, I doubt anyone got the boards printed and shipped to them. Maybe O2 has some

I guess I'll say that I had some. The first batch of 10 is gone. They've been snapped up by Forum members, Lol. My PM box has been very active with messages from other members seeking them also, so I ordered enough PcB's and the associated parts to build 20 more.

Pardon me if this is a dumb question, but I've seen several DIY LED builds that use the Chester's Garage LED Power Shield with an Arduino for LED dimming on up to four channels.
http://www.chestersgarage.com/new-store/index.php?main_page=product_info&cPath=1&products_id=6
From what I can see, the O2Surplus 4-up and 5-up boards provide roughly the same capability at a fraction of the price (ie. I can build one for <$50 vs $150+ for the Chester's shield).
If my goal is to use the PWM outputs of an Arduino-based controller (Typhon, Jarduino, etc) through an O2Surplus board to drive & dim several strings of LEDs, what am I missing that the extra $100+ for the Power LED Shield would get me (other than "being on a shield")?

Hello here's my full home diy home iteration for LDD based on this topic.
The layout : single layer 150x70mm with two power supply possibility through mooex connexion, PWM RJ45 connection to Arduino and
So the board physicaly built
RJ45 interconnection board to Aduino
Ligthning result. It's a 3x20W custom multichip (left one on picture)
I use for moment 3 chanel from LLD board so have two more possibility on board for spectral supplementation

Hi Rick,
It's a friend Diy layout and solder work. Baord was etch by Itead studio. It has RTC on board. I really fine shield with good acces to screw connections
Marc
From what I can see, the basic shield costs $40 then you have to add the cost of each RECOM driver added to the shield. The RECOM drivers cost $30 each (1000ma version). There's your extra $120, and it's just for the drivers.
You could by 6 MeanWell LDD-1000H for the same cost as 1 RECOM, if you know where to shop.LOL LDD-1000H | Mean-Well LDD-1000H | USA Warehouse
If you really want an ARDUINO LDD-H shield, let me know, and I'll re-post the build files.

I could ask him but i don't think so. I was a 10u serie for our local aqua club project.
