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.

Back in February 2014 ARM announced the Lab-in-a-Box (LiB) educational initiative targeted at higher educational institutions around the globe. The Lab-in-a-Box package comprises hardware development boards, professional software licenses from ARM and complete teaching materials from the ARM University Program ready to be deployed in the classroom. These include lecture note slides, demonstration code, lab manuals and...

The Nucleo series of development boards from STMicroelectronics are mbed compatible giving an ARM development environment with headers to take Arduino shields. The STM32 Nucleo board provides a low cost and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features.
