High-quality PCB design – This second-generation board is designed with care, and a great reference for your own designs. Four-layer PCB with dedicated ground and power planes, six external ground connections, power distribution and decoupling capacitors implemented by the book for all ICs.
Open source bootloader - The TinyFPGA BX implements its own open source USB bootloader. Upon power-up, USB bootloader is loaded from SPI flash and becomes active. It appears on the host computer as a virtual serial port device.
Small form-factor is breadboard friendly - There’s plenty of space on either side for connecting jumpers or components. There is no smaller FPGA board available with this many logic resources.
Features
