The accelerometer can detect orientation relative to the Earth's gravity and has a selectable full scale range of ±2, 4, 9 or 16g. The magnetometer detects the direction of the strongest magnetic field and can measure between ±1.3 to 1.8 gauss (±1.3 x 10-4 to 1.8 x 10-4 Tesla). Interfacing to the FLORA main board is very simple using I2C. The chip also has a temperature sensor although it isn't calibrated, so it can be used for measuring temperature changes rather than absolute values.Adafruit provide a free tutorial and an Arduino library to get you started.

| "Adafruit 1559 FLORA RGB Smart Neo Pixel version 2 - Sheet of 20" |
| "Adafruit FLORA Wearable Sensors, Modules and NeoPixels - Adafruit 1559, The Adafruit FLORA Wearable RGB NeoPixels bring extra blinkiness to your next wearable project and what's better than a few RGB LEDs? The answer is a sheet of 20 NeoPixels. These seemingly simple gadgets have triggered an amazing array of creative projects, from watches and compasses to steampunk goggles and more. Each NeoPixel has solder pads for 5V DC and Gnd, plus data-in and data-out, using just 1 x GPIO pin on your FLORA microcontroller. Simply feed the data-out from one NeoPixel into the data-in of another to control them both from the same microcontroller (MCU).These LEDs are quite power hungry, up to 55mA each, and if you use all 20 on one project you are going to need a separate power supply and good copper wire between them. You can still use the conductive thread for the data connections though.Adafruit have published a driver library to save you the trouble and let you get on with designing eye catching displays. They have a reputation for the quality of their supporting documentation and you will find their Uberguide to NeoPixels and their Best Practices guides invaluable. In particular the Best Practices guide will help you prolong the life of your NeoPixels and avoid common mistakes. Adafruit 1559 FLORA RGB Smart Neo Pixel version 2 - Sheet of 20"

| "Adafruit 1059 FLORA Wearable Ultimate GPS Module" |
| "Adafruit FLORA Wearable Sensors, Modules and NeoPixels - Adafruit 1059, The Adafruit FLORA Wearable Ultimate GPS Module is described as ultimate because it's so small, thin, uses so little low-power and has data-logging built-in, it would be hard to imagine what else could be added. It has a few more plusses, such as the internal patch antenna with UFL connector and the array of location service signals it can receive. The MTK3339 GPS chip can track up to 22 satellites on 66 channels, is able to receive the SBAS signals from the WAAS (USA) and EGNOS (Europe) location augmentation services and use local DGPS signals. All these services add up to give the module excellent resolution of better than 3m and a velocity accuracy of 0.1m/s (0.2mph).The built-in ceramic patch antenna should serve you well for most applications, but the module has a UFL antenna connector which can accept any 3V active GPS antenna. If the module detects an external antenna it will switch over automatically. Add a small coin cell battery to use it as a real-time clock taking advantage of the atomic clocks on board the GPS satellites. The module's internal microcontroller can be instructed to log the date, time and position every 15 seconds so long as it has a fix and it has power. If either is lost logging stops and resumes when both are present. Your external FLORA main board only has to send the start logging command and then it can go to sleep while the module does the rest. There's enough on board memory for 16 hours of data.Adafruit provides a free tutorial to get you started, and just for fun they have a FLORA GPS jacket tutorial.

Because they're made from soft silicon, they're washable and you can trim off any buttons you don't want. Adafruit have also made the keypads edge to edge tileable to create larger arrangements. Each button has a conductive ring which makes contact with a properly designed PCB underneath (not supplied). Adafruit provide an EagleCad library so that you can design your own.

The amplifier's automatic gain control will reduce loud sounds and amplify the quiet ones to minimise volume related distortion. You can configure the maximum gain to 40, 50 or 60dB and the Attack/Release ratio to 1:4000, 1:2000 or 1:500 via jumper settings.The amplifier's output is approximately 2Vpp with a 1.25V DC bias making it suitable for sampling with a 3.3V analogue to digital converter (ADC) without the need for a blocking capacitor. However, if you want to connect one to a Line Input then use a blocking capacitor of between 1 and 100µF unless you have a differential amplifier or it already has its own blocking capacitor.Get started quickly using Adafruit's tutorial for this board showing how to wire one up to a set of headphones. Having mastered that, you can move on to connecting one to a microcontroller. Adafruit have a tutorial and FFT library for the Arduino which extracts frequency information from the audio and another which is a sound level tutorial.Supplied with a fully assembled amplifier board, and a strip of 0.1in. header pins for you to solder on if required.
