STM8AL board dedicated resources

The STM8AL board is designed around the STM8AL3L68T microcontroller in a 48-pin

LQFP package.

Figure 11 illustrates the connections between the STM8AL3L68T and the different

peripherals (ST-LINK/V2, L99PM62GXP IC, push buttons, LED, IDD measurement circuitry,

LCD and connectors).

Figure 11 and Figure 12 help you to locate these features on the STM8AL board.
