1 OVERVIEW
NuMaker Tomato is an open development board. The NuMaker Tomato development platform
enables you to design prototypes for Internet of Things (IoT) devices, Gateway / Router or audio
stream application and Ethernet industrial control, using hardware and an API that are similar to
those offered for Arduino boards.
The platform is based on Nuvoton 300MHz ARM9 SoC which is highly integrated System-on-Chip
(SOC) design, The SoC provides features such as 10/100Mbps Ethernet, high-speed USB 2.0
host/device ports, and built-in 64M Byte DDRII memory .
The NuMaker Tomato uses the NUC976DK62Y as the target microprocessor. Figure 1-1 shows
the NuMaker Tomato board.
