MyoWare Cable Shield

The MyoWare Muscle Sensor is now designed to be wearable allowing you to attach biomedical sensor pads directly to the board itself. However, there still may be cases where you want to mount the sensor pads away from the other hardware, this is where the MyoWare Cable Shield comes in. This shield provides a 3.5mm jack where you can attach a three electrode sensor cable allowing you to test and use the MyoWare Muscle Sensor without actually attaching it to your person.

The MyoWare Cable Shield is equipped with two rows of 3-pin plated through holes on each end of the board. This allows for standard 0.1" headers to be used to stack the shield with other MyoWare boards.

The MyoWare Muscle Sensor, that this shield attaches to, is an Arduino-powered, all-in-one electromyography (EMG) sensor from Advancer Technologies. The MyoWare board acts by measuring the filtered and rectified electrical activity of a muscle; outputting 0-Vs Volts depending the amount of activity in the selected muscle, where Vs signifies the voltage of the power source.

Papilio Duo-512KB FPGA and Arduino-Compatible Chip

The Papilio DUO has an FPGA on the top and the same chip that is used in the Arduino Leonardo (ATmega32U4) on the bottom. It's like having an Arduino with a full circuit laboratory connected to it! For example, you can draw circuits to move pins, connect extra serial ports, or connect a bitcoin miner to the Arduino-Compatible chip. Just plug it into your computer using a USB cable, download our software and start drawing your own circuits.

FPGA Unleashed!
Our dream is to take the hardcore out of FPGA (Field Programmable Gate Array) and make it an amazing tool that anyone can use for creative technology projects. 

Just like the Arduino team simplified C++ programming, we simplify FPGA design by providing easy to use drag and drop circuit libraries. We believe that drawing circuits will result in an amazing outpouring of creative FPGA projects!

Use the Papilio DUO to unleash your inner DaVinci. Draw and debug circuits on a chip without any soldering, breadboarding, or weird programming languages. Set your imagination free and put an FPGA in your creative arsenal!

Hardware
The Papilio DUO is a third generation Papilio board. As such, it benefits from all of the tricks we've learned along the way as well as extensive feedback from the community.  This past experience and community feedback drove the development of this board and puts the users needs first.

Extensible - The first thing that people always ask for is the ability to use their Arduino shields. We listened and started with an Arduino-Compatible footprint, retained support for six Papilio Wings, and even squeezed in support for one PMOD connector! Adding new hardware to your FPGA has never been easier, there is a huge selection of hardware out there just waiting for you to discover.

SRAM - Easy to use SRAM is a must. We've used SDRAM in the past and it was a big mistake! The strict timing requirements and interfacing caused fits for everyone. SRAM is asynchronous and dead easy to use, you will greatly appreciate the simplicity of SRAM in your projects.

Software and Features
The Papilio DUO is much more then just hardware. In fact, the software is the secret sauce that sets the DUO apart from other FPGA boards. It lets you draw up circuits without investing time and energy in learning VHDL/Verilog.

We start with the Arduino IDE (Integrated Development Environment) and supercharge it by adding circuits into the mix. We bring all of the pieces needed to draw and debug your very own circuits in one place. It's an easy and seamless user experience that we call Papilio DesignLab for use with both Windows and Linux.

Papilio DesignLab
We start with the Arduino IDE but every sketch now has a circuit associated with it - editing and debugging circuits is just a click away!

Simply draw and debug your circuits!
Click on the "Edit Circuit" button and simply draw your circuits using the Xilinx ISE schematic editor and our Papilio Circuit Library.

Logic Analyzer
Drop a professional quality Logic Analyzer into any circuit and know instantly what it's doing. Up to 32 channels and 200Mhz speed handles any circuit you can throw at it. Use up to 75KB of internal memory or the external SRAM memory.

System on Chip - Draw Soft Processor Circuits!
Want to get into more complex circuits? DesignLab includes the ZPUino Soft Processor with a Wishbone bus, providing greater speed and flexibility than the Arduino-Compatible chip. A Soft Processor runs inside the FPGA and uses the Wishbone bus to make it easy to connect peripheral circuits, such as UARTs, PWMs or SPI masters. Making your own Soft Processor with just the right mix of peripheral circuits is known as a SOC (System On Chip) design. With DesignLab you can draw your SOC designs in minutes! 

Create SOCs with ten serial ports, or a PWM on every pin, or something exotic like classic Atari and Commodore audio chips connected at the same time. The sky is the limit, you can create things that don't exist anywhere else!

Example of making your own SOC design with ZPUino and a Commodore 64 SID audio chip. (This tutorial was written for an earlier version of our software. DesignLab integrates circuits and sketches together for a much easier and seamless user experience.)

Arduino Expansion Shield for Raspberry Pi B+ (Compatible with RPi 2 Model B)

We all know Raspberry Pi is a mini-computer running on Linux operating system; while Arduino is a microcontroller running on simple I/Os. Both of them focuses on very different areas. Compared with Arduino, the Pi gets much better computing performance.

So What happens when a Pi meets an Arduino?

A simple example would be, when building a mobile robot, we use the Raspberry Pi to extend its vision and get a nice tiny monitor. Meanwhile, Arduino handle nicely with the motor driving part and delivers fast responses like obstacle avoidance. Because, without the OS, the response time of rapid changes on the Arduino is much shorter. Also the high performance Pi can deals much easily with wireless communications, imaging and running complex algorithm.

Therefore, with the Arduino and Pi together, you get a powerful "brain" and "cerebellum" for your project, at one time.

MyoWare Muscle Sensor

Using our muscles to control things is the way that most of us are accustomed to doing it. We push buttons, pull levers, move joysticks… but what if we could take the buttons, levers and joysticks out of the equation? This is the MyoWare Muscle Sensor, an Arduino-powered, all-in-one electromyography (EMG) sensor from Advancer Technologies. The MyoWare board acts by measuring the filtered and rectified electrical activity of a muscle; outputting 0-Vs Volts depending the amount of activity in the selected muscle, where Vs signifies the voltage of the power source. It’s that easy: stick on a few electrodes (not included), read the voltage out and flex some muscles!

The MyoWare Muscle Sensor is the latest revision of the Muscle Sensor of old, now with a new wearable design that allows you to attach biomedical sensor pads directly to the board itself getting rid of those pesky cables. This new board also includes a slew of other new features including, single-supply voltage of +3.1V to +5V, RAW EMG output, polarity protected power pins, indicator LEDs, and (finally) an On/Off switch. Additionally, we have developed a few shields (Cable, Power, and Proto) that can attach to the Myoware Muscle Sensor to help increase its versatility and functionality!

Measuring muscle activity by detecting its electric potential, referred to as electromyography (EMG), has traditionally been used for medical research. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into all kinds of control systems.

Note: Biomedical sensor pads can be found in the Recommended Products section below to be purchased separately.
