According to the statistics of research institutes, the number of globally networked devices in 2020 exceeded 20 billion units. More than half of them (10 billion) was IoT (Internet of Things) devices. This number continues to increase; it is estimated that by 2025, globally networked devices will exceed 30 billion units. Among the networked IoT applications, many functions had to be realized through Linux, but product development with traditional Linux is complex. The main reason is that it is difficult to set up Linux development environments and complicated hardware settings, which all cause the development schedule to increase.

Nuvoton’s Chili Board is for solving difficulties encountered by users, allowing developers not having to waste time setting up Linux interactive compilation environments and not having to perform complicated network settings; use the VMware virtual machine and Linux BSP provided by Nuvoton to complete the development of Linux networking quickly. Chili Board also provides support for multiple software, including simple network management protocol (SNMP), network file system (NFS) and web server, etc.; it also supports functions such as OpenSSL (TLS) secure communication, etc. For network connections, in addition to the wired Ethernet, the USB2.0 HS host can also be used to expand wireless networking methods such as Wi-Fi, 4G LTE, NB-IoT, etc., making it easy for developers to develop various networking applications quickly.

After IoT devices are networked, the most important thing is to connect to the cloud; with cloud support, AI computing can be expanded, and big data can be saved and used. Nuvoton’s Chili Board can directly support mainstream cloud services on the market, including Arm Pelion, AWS (Amazon Web Services), Microsoft Azure, Ali Cloud, TTN (The Things Network), etc., allowing developers to deploy various cloud terminal applications quickly.

Nuvoton’s Chili Board is applicable for remote power monitoring (BMS) of factory equipment, power management monitoring (PDU), intelligent buildings, and many other fields, helping developers complete networking and support multi-cloud applications quickly.
