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 (ST-LINK, 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).

2.2 ST-LINK The ST-LINK provides a USB interface for programming and debugging using a single wire interface module (SWIM). The ST-LINK module of the STM8SVLDISCOVERY also supplies 5 V and 3.3 V to the STM8S003K3T6 module.
2.2.1 Using the ST-LINK
Figure 6. Typical configuration
Note: The driver for ST-LINK is installed automatically when the USB is connected.
For information about debugging and programming features refer to ST-LINK, STVD, STVP and SWIM on www.st.com.
2.2.2 Using the ST-LINK on other STM8S applications
You can connect your ST-LINK to other STM8S applications in 2 ways:
● By removing the solder bridges: This way uses the ST-LINK without breaking the PCB. Unsolder the two solder bridges SB1 and SB2 under the SWIM connector. See Figure 7. You can re-solder the two bridges at a later date thus keeping the STM8SVLDISCOVERY usable.
● By breaking the board and removing the ST-LINK: This way constitutes a good alternative to programming the STM8S devices in other applications. See Figure 8.
Note: This ST-LINK only supports the STM8S family. Do not use it with other STM8 families.

Warning: By removing this module you will lose power supply on the STM8S003K3T6 evaluation board. Consequently, you will need a SWIM cable and an external power supply to program and use the STM8S003K3T6 board. To reconnect your STM8S003K3T6 use connector CN7 see Table 1.

2.3 Power supply and power selectionThe power supply is provided by a USB connector. Jumper JP1 selects the VDD value (5 V or regulated 3.3 V) see Figure 9.
Figure 9. Power selection
2.4 LEDsThe ST-LINK provides two LEDs:
● LD1: Green LED LD1 is connected to the I/O PD0 of STM8S003K3.
● LD2: Red LED LD2 indicates communication between PC and ST-LINK.
2.5 Push buttonPush button B1 is connected to the I/O PB7 of STM8S003K3.
