4.3 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, I
DD
measurement circuitry,
LCD and connectors).
Figure 11 and Figure 12 help you to locate these features on the STM8AL board.
