Pololu Wixel Shield for Arduino User's Guide © 2001–2014 Pololu Corporation 1. Overview The Wixel shield [http://www.pololu.com/product/2500] seamlessly enables a wireless link (with a typical range of ~50 feet) to replace your Arduino’s USB interface, which means you can use the standard Arduino computer software to: • wirelessly program the Arduino (this feature is not available with the Arduino Leonardo [http://www.pololu.com/product/2192]). • wirelessly debug sketches with the Arduino serial monitor.

Pololu Wixel Shield for Arduino User's Guide © 2001–2014 Pololu Corporation Voltage Dividers The shield has four general-purpose 2/3 voltage dividers that can be accessed by the lower “HV” and “LV” pins (pictured above) located between the Wixel socket pins. These voltage dividers can be used to safely connect 5 V outputs to the Wixel’s 3.3 V inputs: connect the 5 V signal to one of the four HV pins and then connect the corresponding LV pin to the Wixel pin of your choosing.

The pushbutton pins are brought out to a series of through-hole pads that you can connect to other parts of your circuit.

[http://www.pololu.com/file/download/wixel-shield- 1.e. Dimensions The shield board dimensions are 2.02" × 2.56" (within the profile of the standard Arduinos). When the shield—with a socketed Wixel—is plugged into an Arduino Uno, the entire assembly is 1.3" tall.

What You Will Need The following materials are necessary for getting started with your Wixel shield for Arduino [http://www.pololu.com/product/2500]: • An Arduino. Using this product as an Arduino shield (rather than a general-purpose Wixel prototyping board) requires an Arduino. Wixel shield should work with all Arduino and Arduino clones that have the standard Arduino pinout and use a serial bootloader.

Pololu Wixel Shield for Arduino User's Guide © 2001–2014 Pololu Corporation Once the male header pins are installed, the Wixel can be plugged into the female socket on the Wixel shield. You can skip this step if you purchased a fully-assembled version of the Wixel [http://www.pololu.com/product/1336]. 2.c. Configuring the Wixels Before your Wixels will work with the Wixel Shield for Arduino, they need to be programmed with a compatible app.

Pololu Wixel Shield for Arduino User's Guide © 2001–2014 Pololu Corporation • P0_0 – the Arduino is held reset while this pin is high • P1_6 – Wixel TX/Arduino RX • P1_7 – Wixel RX/Arduino TX The other 12 general-purpose I/O pins including 5 analog inputs are free to be used by your app to interface with the Arduino or other electronics. A good starting point for making your own compatible app is to modify the source code for the Wireless Serial App [http://www.pololu.com/docs/0J46/9.

Writing Sketches for the Wixel Shield Writing sketches for the Wixel shield is as easy as using the standard serial library to transmit and receive serial data. Note that when first enabling the serial port, you might receive an invalid serial byte as a result of noise on the serial lines. You can keep the Wixel from receiving this noise byte by delaying for ten milliseconds before and after calling Serial.
