Crowd Supply TinyFPGA BX Development Board

Crowd Supply TinyFPGA BX Development Board is a tiny open FPGA module with all the components and circuitry required for the FPGA to function. The BX module allows designing and implementing digital logic circuits in a tiny form factor perfect for breadboards, small spaces, or custom PCBs. The TinyFPGA BX board can be designed using a digital design language or a schematic entry tool. This development board offers 1.3mA active power, 50ppm stability, and a 16MHz low-power MEMs oscillator. The TinyFPGA BX board includes 8Mbit of SPI flash, 3.3V onboard voltage, and 1.2V LDO voltage regulators.
