Review: a look at the STM32L4R9I-EVAL evaluation board
The STM32L4R9I-EVAL board from STMicroelectronics is intended as a demonstration and development platform for their Arm-Cortex-M4-based STM32L4R9AI microcontroller. Besides the size of the board and the many components that populate it, the user’s attention and curiosity are immediately drawn by the unusual 30 mm (1.2”) circular smartwatch display just below the centre. This is more or less the star of the board, while the MCU itself is so unobtrusive that it is easy overlooked.
