Want to design real microchip-style logic at home without a five-figure toolchain? Here is what you would need to get started with the new Adiuvo Explorer Board: the $99 board itself, a single USB-C cable, and AMD's free-tier Vivado tools running on a modest laptop. That is genuinely it — no bench power supply, no separate JTAG programmer, no add-on debugger. For an ECE student or a school robotics team, that shopping list is the whole point.
What the Explorer Board actually is
FPGAs let you build custom digital circuits in reconfigurable hardware — the closest most makers will ever get to rolling their own silicon. The Explorer Board is an open-source platform built around the AMD Artix UltraScale+ AU7P FPGA, aimed squarely at learners who have been priced out of serious FPGA hardware. It is pitched as a board you can grow with: gentle enough for a first Verilog blink, capable enough for a capstone project that talks to real high-speed peripherals.
The specs that matter
Under the hood you get 82,000 system logic cells, 216 DSP slices, and 3.8 Mb of block RAM — plenty for signal processing, soft CPU cores, or parallel sensor pipelines. Power, programming, and serial communication all share one USB-C connector, with an onboard FTDI chip handling JTAG and UART. Four standard Pmod headers let you bolt on sensors, displays, and motor drivers, while high-speed Zmod and SYZYGY interfaces plus four GTH transceivers push up to 12.5 Gbps for the ambitious. Clever engineering keeps it cheap: the designers route a fine-pitch BGA using ordinary PCB fabrication through an offset through-hole via trick, so the board does not need exotic manufacturing.
Why it belongs on your bench
The whole project is open source — schematics, PCB layouts, and reference designs are being published, so you can study exactly how a modern FPGA board is built or fork it for your own design. That transparency turns the Explorer Board into a teaching tool as much as a dev board. If you have been curious about FPGAs but scared off by the cost, this is one of the friendlier on-ramps we have seen.
