STM8A-DISCOVERY
Discovery kit for STM8A microcontrollers
Introduction
The STM8A-DISCOVERY helps you discover the STM8AF and STM8AL automotive
microcontroller family features and develop your applications through two dedicated
application boards that can be connected together via a LIN network.
The STM8AF board can perform both CAN and LIN communications with the MCU powered
at 5 V and is ready to be connected into a network with its integrated transceiver.
The STM8AL board manages LIN slave communication through its transceiver and uses a
4-digit alphanumeric LCD display with the MCU powered at 3.3 V, offering low energy power
modes.
Both STM8AF and STM8AL boards include push buttons, LEDs, external connectors and
allow various configurations to take advantage of the numerous capabilities of the
microcontrollers.
