+README
+======
+
+ This README discusses issues unique to NuttX configurations for the
+ STMicro STM32L0538-DISO development board. The STM32L0538-DISO board
+ is based on the STM32L053C8 MCU (64Kbytes FLASH, 8Kbytes of SRAM and
+ 6Kbytes of EEPROM).
+
+ The board features:
+
+ - An ST-LINK/V2-1 embedded debug tool interface,
+ - 2.13" E-paper display, 122×250 pixels
+ - USB 2.0 FS
+ - One linear touch sensor or four touchkeys
+ - IDD current measurement
