Convenient DIP Package

Mercury has 64 round machine header pins in a familiar dual in-line package (DIP) format. No proprietary expansion connectors - just drop it right into a breadboard!

Mercury is perfect for rapid prototyping, and the super tiny form-factor makes it easy to embed into a small project. We've taken care of the voltage regulators, bypass capacitors and USB configuration circuitry, freeing you to focus on your actual design!

Flexible I/O

Most FPGA development boards are limited to 3.3V digital-only I/O, but we built Mercury with more flexibility in mind: We've included an onboard 8-channel SPI ADC (10 bit, 200 Ksps), great for interfacing with sensors or for audio input. It also has 30 pins of 5V-tolerant digital I/O, so you can safely interface TTL-level devices with the 3.3V Spartan-3A FPGA.
