STM8S-Discovery kit je najlacnejší a najrýchlejší spôsob ako spoznať procesory STM8S a ako si vyskúšať vytváranie a ladenie aplikácií s týmto MCU.

Je to "Quick-start" evaluation board, s osadeným procesorom STM8S105C6T6.
Obsahuje debugger ST-LINK a dotykové tlačítko (Touch-sense).

Vlastnosti

• STM8S105C microcontroller
  
• Powered by USB cable between PC and STM8S-DISCOVERY
  
• Selectable power of 5 V or 3.3 V
  
• Embedded ST-Link for STM8S
  
• USB interface for programming and debugging
  
• SWIM debug support
  
• Touch Sensing button, TS1
  
• User LED, LD1
  
• Extension header for all I/Os
  
• Wrapping area for users own application

Zaujiímavosťou tejto dosky je jej tvar. Priam nabáda na zlomenie.
A o to ide. Ak Vás prestane baviť, zlomíte ju, a ostane Vám ST-LINK debuger na USB.

To že je to najlacnejšie riešenie je pravda, Veď za 7,- dolárov (odporúčaná cena ST) dostanete USB programátor/debugger, procesor, a pár IO pinov.
