Hardware and layout	UM1482

2 Hardware and layout

The STM8SVLDISCOVERY is designed around the STM8S003K3T6 microcontroller in an LQFP32 package. It has two distinct sections that may be separated, the STM8S003K3T6 module and the ST-LINK module.

Figure 2 illustrates the connections between the STM8S003K3T6 and its peripherals (STLINK, user button, LED and connectors).

Figure 3 helps you to locate these features on the STM8SVLDISCOVERY board, as well as the potential point of separation (for more details refer to Section 2.2.2: Using the ST-LINK on other STM8S applications).
