NuMaker-RTU-NUC980, also known as Chili, is a Nuvoton’s development platform that uses NUC980DR microprocessor with a 64-pin package on a 50 mm x 50 mm dimension PCB. This Chili PCB has already embedded Linux operating system and does not have to prepare a cross complier environment. Users can begin develop software application and control a LED light within 5 minutes.

Chili Board embeds Linux v4.4, NFS(Network File System) and webserver functions. To accelerate development, Nuvoton provides sample code like LED control, Wi-Fi connection, Bluetooth control etc.

Not only providing a whole developing environment, Chili board provides a high-end hardware features including a NUC980DR ARM926EJ-S processor with 64 MB DRAM, 32MB SPI NOR Flash, 10/100 Ethernet MAC interface, USB 2.0 High Speed host/device connector, CAN bus, RS-485 and five GPIOs. Crypto engine supports RSA2048, AES256, ECC, SHA512 algorithm and a Pseudo Random Number Generator for communication security protection.

Chili board is a small system which can run Linux on it. Nuvoton provides a full development environment and high-end hardware features. To those who need operation system and internet applications, Chili board is a fast-developing and suitable platform for them.
