Round gadget for colourful LED projects (Arduino compatible)

Works with Adafruit's NeoPixel library for Arduino. If you already have an Arduino board and don't need the on-board microcontroller, just connect 5V, GND and feed the Neopixel data into the DAT pin…

Specs:

TQFP footprint for ATmega168/328 chips
16 MHz resonator option (Murata CSTCE16M0V53-R0)
Space for 8x WS2812B + decoupling capacitors
4x M2 mounting holes
Standard 6pin ISP header
Standard 6pin FTDI header
ALL ATmega pins broken out (1.27mm headers)

Minimum BOM to build:

8x WS2812B intelligent RGB LED pixels
8x 1µF ceramic capacitor (0805)
1x ATmega168/328 TQFP32 7x7mm
1x 10k resistor (0805)
2x 100nF ceramic capacitor (0805)
1x 4.7µF ceramic capacitor (0805)
1x 6pin header for FTDI code upload
1x 3x2p header for ISP programming

Optional BOM parts:

1x 16 MHz resonator option (Murata CSTCE16M0V53-R0)
4x 8pin header 1.27mm (50mil) to access ALL microcontroller pins

Suggested tools:

Soldering iron + flux + solder
ISP programmer (avrispmkII, usbtiny...)
FTDI-compatible USB-adapter with DTR for auto-reset

Dear Seller,

I got your PCB. But why did you sent it to me in a big paperbox filled with garbage, for 5 USD? I think that you wasted my money. I like to receive such a small 4cm diameter PCB in a padded envelope, for much less shipping cost from Germany to Hungary. I am not satisfied with your shipping mode. :-(

Response from madworm | Feb. 28, 2014

I'm sorry you don't agree with my shipping method. I would prefer sending PCBs in letters as well, but that doesn't really work with German postal service.

The fee structure of German postal service is tricky for small parts:

0-20g, 21-50g, 500g-2000g, ...

The small weight letters can't be thicker than 5mm, or they will cost more. Now take a few circuit boards, add the letter, the padding, maybe some cardboard to make it stiff enough (so the thin boards don't break in the sorter-machine...) and the weight is above 50g and costs the rate I charge.

A long time ago, even before using tinde, I made the decision to ship everything in those boxes and be sure stuff arrives in good condition. I understand you're annoyed, but obviously I can't change what the postal service charges.
