Mojo v3 FPGA Development Board

Product Overview

The Mojo v3 is a user-friendly digital logic development board designed around the powerful Xilinx Spartan-6 XC6SLX9 FPGA. Engineered specifically to make learning and prototyping with digital hardware accessible, the Mojo v3 combines high-performance programmable logic with a seamless USB interface powered by an integrated ATmega32U4 microcontroller.

Technical Architecture

At the core of the Mojo v3 is the Xilinx Spartan-6 XC6SLX9 FPGA, featuring 9,152 logic cells, 576Kb of block RAM, and integrated DSP slices suitable for complex digital design tasks. An onboard ATmega32U4 microcontroller acts as a USB interface and FPGA programmer, while also providing an integrated 8-channel, 10-bit analog-to-digital converter (ADC) for processing external analog signals.

Key Features and Connectivity

The board breaks out 84 general-purpose digital I/O pins running at 3.3V logic levels, along with 8 analog input pins connected to the ATmega32U4. It features 8 user-assignable LEDs, a reset button, and onboard SPI Flash memory for permanent storage of FPGA bitstreams. Power and data transmission are conveniently handled through a single micro-USB connection, supported by onboard voltage regulators supplying stable core (1.2V) and I/O (3.3V) rails.

Applications

Ideal for students, hobbyists, and professional hardware engineers, the Mojo v3 is suited for learning Verilog/VHDL, developing custom hardware accelerators, driving complex high-speed peripherals, real-time video processing, and general digital circuit design.
