Wixel Shield for Arduino, v1.1 Pololu 2513

Wixel Shield for Arduino, v1.1  Pololu 2513

The Wixel shield seamlessly enables a wireless link (with a typical range of ~50 feet) to duplicate the functionality of your Arduino’s USB interface, which means you can use the standard Arduino computer software to:

• wirelessly program the Arduino (this feature does not work on the Leonardo or the A-Star 32U4 Prime).
• wirelessly debug sketches with the Arduino serial monitor.
• wirelessly communicate with the Arduino from your computer’s virtual COM port.

More generally, the shield can also be used for wireless communication between an Arduino or Arduino clone and other embedded systems (including additional Arduinos). Alternatively, this board can also be used without an Arduino as a general-purpose Wixel prototyping board.

The Wixel shield does not interfere with the Arduino’s existing USB circuitry, so the Arduino’s traditional wired USB connection can still be used while the shield is connected.

Shield Features

• Wireless sketch uploading using the standard Arduino IDE
• General-purpose wireless serial communication between an Arduino and a computer or other electronics
• Prototyping space for easier/cleaner construction of custom circuits
• Shield-accessible Arduino reset button and pin 13 LED
• Four general-purpose 2/3 voltage dividers (can be used to safely connect 5V signals to 3.3V inputs)
• Two general-purpose MOSFETs (can be used as level-shifters or high-current outputs)
• Wixel socket allows the Wixel to be removed and used for other applications
• Comprehensive user’s guide

Version 1.1 details

This is version 1.1 (v1.1) of the Wixel Shield, which replaces the original Wixel Shield for Arduino. It adds pass-throughs for the four new pins (SCL, SDA, IOREF, and an unused pin) introduced on the Arduino Uno R3 and present on all newer Arduinos. (The original Wixel Shield was designed before the R3 was released.) The v1.1 shield also features improved level shifter circuits that convert between the voltage on the Arduino’s IOREF pin and the Wixel’s 3.3 V, allowing it to work automatically with 3.3 V and 5 V Arduino boards. Generally speaking, most users should not notice any other differences between the two shield versions; details can be found in this section of the user’s guide.
