STEVAL-LLL002V1 connections
2.1
Power supply
The
STEVAL-LLL002V1
The power source must deliver sufficient current depending on the input voltage for proper functioning.
Reverse voltage protection and input surge protection are provided to avoid any damage.
2.2
Microcontroller SWIM
The STEVAL-LLL002V1M board is equipped with a standard 4-pin SWIM connector allowing to debug and
develop the
STM8AF6266
2.3
Jumpers for LED open-circuit simulation
LED errors can be simulated by using J5 to J8 jumpers.
Removing a jumper on J5, J6, J7 and J8 causes LED open-circuit error in D48, D49, D50 and D51 respectively.
These simulated errors can be detected in error detection mode: the defective LED is signaled by lighting the
adjacent LED on the board in standalone mode, and by flashing the corresponding light in the LED map in GUI
mode.
