DE0-Nano - Altera Cyclone IV FPGA starter board [discontinued] Connector_DB9 these LEDs have 2 wires

these LEDs have 2 wires (input and output) for sending data - one clock pin and one data pin

hardware SPI support

External power supply: 7~23V DC

this box is ready to go - with ten 25ft reels of different colour stranded-core 22AWG prototyping wire easily accessible via the pre-punched reel holes

SEL0 and SEL1 are reversed on the silkscreen

DE0-Nano - Altera Cyclone IV FPGA starter board [discontinued] Connector_DB9 these LEDs have 2 wires*** Please note: this is NOT the DE10 Nano! *** For every day projects, microcontrollers are low cost and easy to use. But when you have a project that needs raw power and high speed you may want to check out FPGAs (Field Programmable Gate Arrays). FPGAs are like raw chips that you can design by hand. They run very fast and very efficiently. They are designed for mass parallel execution so they're very good at handling a lot of I O pins at once,
