-This boards contains a STM32G491xC microcontroller with a top speed of 170 MHz.+This boards contains a Cortex M4 STM32G491xC microcontroller with a top speed of 170 MHz.
  
-This board was programmed twice before LD1 flagged a USB communication failure +The MCU has 512 KB of program flash, and 112 KB of RAM.
-whilst in operation and it no longer enumerates on the bus.+
  
-A new device will be ordered and this page updated at a later time, however, the +STLINK on this board does not work on a USB1.1 hub.
-target can be programmed via PA13 and PA14 with the STLINK/V3 held in reset +
-with JP1 and power set to 5V charger. +

-NB the embedded STLINK/V3 programmer did not work on a USB1.1 hub or this was +
-a symptom of future failure (see above).+
  
 +The target can be programmed using STLINK on-board or via PA13 and PA14 with
