STM8L101-EVAL
evaluation board
Introduction
The STM8L101-EVAL is composed of two boards:
■
An STM8L1/L2 motherboard called MB709 which includes all peripherals which are
connected to the MCU on the daughterboard. The motherboard connects to the
daughterboard via two 36-pin connectors.
An STM8L1 daughterboard called MB710 which has an STM8L101 MCU.
■
The motherboard and daughterboard are a complete development platform for
STMicroelectronic's STM8L101 microcontroller with comparator, I2C, SPI, USART and
SWIM debugging support.
The full range of hardware features on the STM8L101-EVAL helps you to evaluate all
peripherals (MicroSD card
TM
, USART, EEPROM, LCD, for example) and develop your own
applications.
