TinyFPGA A2

Low-cost, open-source FPGA boards in a tiny form factor

The TinyFPGA boards are a new series of low-cost, open-source FPGA boards in a tiny form factor.

Because they were designed to be the least expensive, they do not include a built-in USB interface. Instead they rely on JTAG programmers.

Solder on pins for use in a breadboard or PCB socket; or solder connectors, wires, and components directly onto the board.

The A-series boards use either XO2-256 (A1) or XO2-1200 (A2) FPGAs from Lattice. 

Common Features

• Small form-factor that is breadboard friendly; plenty of space on either side for connecting jumpers or components.
• Easily accessible JTAG interface pins located both on the side IO connectors as well as a header on the top of the board. This is an inexpensive way to support in circuit programming and testing.
• Low-power and low-cost design relies on integrated FPGA functionality: internal configuration flash memory, internal clock generator, and fixed 3.3v power supply requirement. External memory, clocks, and power supplies can be added external to the board.
