Some great new products in stock today! All by way of Adafruit.
First we have the Electret Microphone Amplifier which has great performance over similar sized and priced breakouts. If you want to see it in action with the Adafruit Waveshield check out this awesome video
The next is a rather groovy bicoloured 8x8 LED matrix with I2C backpack. Which means you can control all 64 LEDs, in three different colours - yes three - since you can switch on the red or the green or the red AND green which will give you yellow (subtractive colour mixing you see). All with just a few pins...
That's the matrix in all it's glory!
