Lilypad vs. Flora

by blf on Wed Mar 06, 2013 10:30 am

Hi, NOOB here.

Are the Lilypad and Flora virtually the same thing? Do both use the Arduino software for uploading and the same programming commands? I assume Flora and Lilypad are "interchangeable" in terms of I can so X with Lilypad, so I can do X with the Flora.

Any experience out there with one vs the other?

thanks for posting, we have a detailed feature/spec listing here:
http://adafruit.com/products/659

The FLORA is small (1.75" diameter). We wanted the smallest possible board for our wearable platform.

It's based on our experiences shipping our own, shipping, customer-tested Atmega32u4 Breakout Board.

The FLORA comes with projects at launch, the FLORA addressable and chain-able 4,000 mcd RGB LED pixels, ultimate GPS module, premium stainless steel thread.

The FLORA has built-in USB support. Built in USB means you plug it in to program it, it just shows up. No additional purchases are needed! Works with Mac, Windows, Linux, any USB cable works great. Currently the PCB comes with a mini B connector but future versions may change to microUSB. The FLORA has USB HID support, so it can act like a mouse, keyboard, MIDI, etc. to attach directly to cellphones.

The FLORA has a small but easy to use onboard reset button to reboot the system. The power supply is deigned to be flexible and easy to use. There is an onboard polarized 2 JST battery connector with protection schottky diode for use with external battery packs from 3.5v to 16v DC in. Can be used with LiIon/LiPoly, LiFe, alkaline or rechargeable NiMh/NiCad batteries of any size. The FLORA does not have a LiPo charger included by design, this allows safe use with multiple battery types and reduces risk of fire as it is not recommended to charge these batteries on fabric.

The FLORA has onboard power switch connected to 2A power FET for safe and efficient battery on/off control. Often FETs are not included in other designs that leads to switch failure as small SMT switches are rated for only 20mA current use. The FLORA has an onboard 3.3v 100mA regulator with protection diode and USB fuse so that power is consistent and can power common 3.3v modules and sensors.

We spent a lot of time on the power supply because the FLORA power system is specifically designed to allow easy control and power of a large quantity of digital RGB LED pixels such as the FLORA pixel series of accessories.

The FLORA is fabric friendly. The FLORA does not use FTDI headers (built in USB support) headers of any kind sticking out can grab and tear fabric.

The FLORA is extremely beginner-friendly - it is difficult to destroy the FLORA by connecting a battery backwards due to polarized connector and protection diodes. The onboard regulator means that even connecting a 9V battery will not result in damage or tears.

The FLORA has 4 indicator LEDs: power good, digital signal LED for bootloader feedback, data rx/tx. Also onboard is an ICSP connector for easy reprograming for advanced users.

There are 14 sewing tap pads for attachment and electrical connections. Data buses are interleaved with power and ground pads for easy module and sensor attachments without worrying about overlapping traces which are not possible with conductive thread.

The FLORA works with the Adafruit-fixed Leonardo-like bootloader and will work with any future released Leonardo-compatible bootloader. FLORA is currently using our bootloader and Adafruit USB vendor ID.

The FLORA comes with Adafruit's support, tutorials and projects. Adafruit has dozens of projects that will be released with the FLORA in 2013 and has staff 100% dedicated to creating tutorials and projects for use with the FLORA.

cheers!

Thanks for the info.

Am I right in assuming the Flora does not accept shields? I was wanting to do more with the wearbles than just LEDs. I'd like to set up some motors and EL wire, possibly even muscle wire.

Clearly they are not going to stack like on an Arduino, but you should be able to interface with shields that are 3.3v friendly. Shields that communicate via I2C or SPI are good candidates. For motor control, you might want to look into Polulo's motor control modules with serial interfaces.

Where can I find examples of doing exactly that?

The Flora uses the same processor as the Leonardo, so LEonardo tutorials such as this one are applicable to the Flora as well:

Apparently the clams about MIDI are wrong. viewtopic.php?f=51&t=51683
