The NeoPixel Jewel is a lovely round PCB, home to 7 tiny WS2812 5050 (5mm x 5mm) smart RGB LEDs. Each LED has a driver chip built into it, making them individually addressable. Many units can be chained together and run by a single microcontroller by connecting the output of one Jewel into the input of another! Each NeoPixel has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and runs on 5V. Want to make a hexapod walker? Maybe you’re making a piece of art with tons of moving parts, or you need to drive a ton of LEDs with precise PWM output. Your microcontroller has a limited number of PWM outputs, and you find yourself running out! Not with the Adafruit 16-Channel 12-bit PWM/Servo Driver – I2C interface. With this pwm and servo driver breakout, you can control 16 free-running PWM outputs with just two pins! Need to run more than 16 PWM outputs? No problem. Chain together up to 62 of these beauties for up to an outstanding 992 PWM outputs. The Analog Feedback Micro Servo may appear to be a normal micro servo, but it is so much more. What makes this little fella special? Beyond the metal gears which keep this servo solid for the long haul in hobby systems, this servo has feedback via a potentiometer wiper on a separate wire that can be read with an analog input, such as those on an Arduino, to get the servo’s position. This gives you the ability to “record” the servo’s motion, or improve stability.
The SparkFun Transceiver Breakout – RS-485 is a breakout board for the SP3485 RS-485 transceiver IC, which will convert a UART serial stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 10Mbps. This board requires a very low amount of power and can operate from a single +3.3VDC supply. This breakout board includes the SP3485 RS-485 transceiver, filter capacitor, and other components shown on the schematic. The RS-485 output has been broken out to three different connections: (1) an RJ-45 connector, (2) a 3-pin 3.55mm screw terminal, and (3) a 3-pin 0.1″ pitch header; none of these output connectors come populated.
