3231-ADA Adafruit LoRa Radio FeatherWing - RFM95W 900 MHz
US$34.92
This is the LoRa 9x @ 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. These are +20dBm LoRa packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweakings.

3006-ADA Adafruit I2S 3W Class D Amplifier Breakout - MAX98357A
US$9.45
We now have an all in one digital audio amp breakout board that works incredibly well with the Raspberry Pi! If you're looking for an easy and low cost way to get you digital sound files bumpin' then the MAX08357 I2S Amp Breakout is for you. It takes standard I2S digital audio input and, not only decodes it into analog, but also amplifies it directly into a speaker. Perfect for adding compact amplified sound, it takes 2 breakouts (I2S DAC + Amp) and combines them into one.

ARD-612 Prototyping Shield for Arduino with mini Breadboard
US$3.84
This is a prototyping shield with a mini breadboard for Arduino. This general purpose Prototype shield is fantastic for wiring your circuits onto a shield permanently by soldering it or wiring using the provided breadboard to create your very own plug and play Arduino shield. There are two buttons (one connected to reset, the other label SW1), through holes for icsp and pads for a 14 pin surface mount IC. It also comes with two LEDs (one connected to pin 13, another connected labelled LED2). The shield will work with UNO, Diecimila and Duemilanove Arduinos (Leonardo will receive support for SPI ,IOREF, SDA,SCL pins due to pin mapping on the device.)
