Your selection here depends on what type of microcontroller youвЂ™ll be using and which of these are supported by the application or library you intend to use.ДЇor example, Arduino based projects work fine with any of these, since everything runs real-time. The advantage of the WS2812 though, is that production of these comboвЂ™s in strips is easier and therefor cheaper, and each RGB LED takes much less space on strips. The WS2811/WS2812 depends on sending data matching a very tight timing. The WS2801 uses a separate clock line, which can be seen as an advantage, whereas the WS2811/WS2812 does not. Where the WS2801 strips needed 4 wires, the WS2811/WS2812 strips only needs 3 wires. Note how the layout of the вЂњsilverвЂќ tracks are almost identical in both images, yet the black (IC) block and the tiny wires are different (right). On the left a 5050 RGB LED, on the right a WS2812 which combines a 5050 RGB LED with a WS2811 controller. In the illustration below youвЂ™ll see the difference:

The 5050 LED is a very common 3 LED (Red, Green, Blue) package, in one 5mm x 5mm case.ДЄ WS2812 is the same package but with an additional WS2811 LED driver IC on board. The WS2812 however is a WS2811 placed inside a 5050 LED package. The WS2801 used to be quite popular but the WS2812/WS2811 appears to be taking over the reigns. Positioned close together, so you as a viewer will see the mixed color result. These ICвЂ™s can control up to 3 LEDs, typically Red, Green and Blue. The WS2801 and WS2811 are LED driver ICвЂ™s ( Integrated Circuits). The model numbers WS2801, WS2811 and WS2812 actually refer to different вЂњthingsвЂќ. Most projects and descriptions out there discus these sometimes mixed, and for one who dives into LED strips for the first time, these models numbers might be confusing.

On-board green power LED and red pin #13 LED Power with either USB or external output (such as a battery) - it'll automatically switch over Up to 16V input, reverse-polarity protection, thermal and current-limit protection. On-board 3.3V power regulator with 150mA output capability and ultra-low dropout. Micro-USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram. USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude and/or the Arduino IDE (with a few simple config modifications).ДЄlso has headers for an FTDI port for reprogramming The bootloader does not affect RAM usage.ДЄTmega328P onboad chip in QFN package running at 3.3V logic

The bootloader on the Pro Trinket use 4KB of FLASH so the maximum sketch size is 28,672 bytes.

The USB connection is for uploading new code only.

This is to keep the Pro Trinket small and inexpensive, you can use any FTDI cable to connect to the FTDI port for a Serial connection. You cannot plug shields directly into the Pro Trinket The onboard power supply is a 3.3V regulator and it can provide 150mA output Only the most timing-specific libraries may be affected, check the documentation! The NeoPixel Library works fine at 12MHz. The Pro Trinket 3V runs at 12MHz, this doesn't affect most projects. Pins #2 and #7 are not available (they are exclusively for USB) Here's some things you may have to consider when adapting Arduino sketches: Pro Trinket is programmable using the Arduino IDE as you already set up, and 95% of Arduino projects will work out of the box! However, it uses 3V logic and 12MHz clock which means it's good when you want a lower-power and lower-voltage setup. The Pro Trinket 3V uses the Atmega328P chip, which is the same core chip in the Arduino UNO/Duemilanove/Mini/etc. So it's great once you've finished up a prototype on an official Arduino UNO and want to make the project smaller. The Pro Trinket PCB measures only 1.5' x 0.7' x 0.2' (without headers) but packs the same capability as an Arduino UNO.

We also added Optiboot support, so you can either program your Pro Trinket over USB or with a FTDI cable just like the Pro Mini and friends. Like the Trinket, it has onboard USB bootloading support - we opted for a MicroUSB jack this time. That's why we designed Pro Trinket, with 18 GPIO, 2 extra analog inputs, 28K of flash, and 2K of RAM. Trinket's a year old now, and while its been great to see tons of tiny projects, sometimes you just need more pins, more FLASH, and more RAM. It's like an Arduino Pro Mini with more pins and USB tossed in. Trinket's got a big sister in town - the Pro Trinket 3V! Pro Trinket combines everything you love about Trinket with the familiarity of the core Arduino chip, the ATmega328.
