Taking a break

 We're taking a break moving shop and hope to be back soon. We hope to start shipping orders in Nov 2018. 

Core3S250E is an FPGA core board that features an XC3S250E device onboard, supports further expansion.
  • onboard 1pcs XCF02S
  • integrated FPGA basic circuit, such as clock circuit
  • onboard nCONFIG button, RESET button, 4 x LEDs
  • all the I/O ports are accessible on the pin headers
  • onboard JTAG debugging/programming interface
  • 2.54mm header pitch design, suitable for being plugged-in your application system
