The TinyFPGA BX brings the power and flexibility of custom digital logic designs to the maker community. The BX module allows you to design and implement your own digital logic circuits in a tiny form-factor perfect for breadboards or custom PCBs.

This incredible power allows you to do things that are not possible with traditional microcontrollers. While microcontroller boards have a fixed set of peripheral devices on-board, the TinyFPGA BX modules can implement the exact peripheral devices needed to get the job done. It’s not software bit-banging, it’s the real deal implemented in digital logic. When the next project has different requirements, reprogram the TinyFPGA BX with a new design suited to the task.

The full potential of programmable logic devices allows for even more ambitious projects than custom microcontroller peripherals. Recreate entire 8-bit computers from history, or design your own.

If you don’t know what the big deal is with custom digital logic, then here’s a great way to learn. Place a TinyFPGA BX down on a breadboard and get to task interfacing it with LEDs, switches, rotary encoders, and any other peripheral, sensor, or interface you might like to try. The low cost of the BX and open-source ecosystem make this an excellent way to get started on a new adventure with digital logic.

Whether you are a hobbyist looking to expand your capabilities, a professional prototyping a new product, or a student learning the ropes of digital design, the TinyFPGA BX can help you on your way.
