The ST STM32L051R8H6 is a 32-bit ARM Cortex-M0+ MCU from the STM32L0 ultra-low-power line, clocked at 32 MHz. It packs 64 KB of Flash, 8 KB of SRAM, and 2 KB of EEPROM on a single die — enough for a sensor hub, a simple HMI back-end, or a battery-powered data logger that wakes, samples, and sleeps.
At 32 MHz the Cortex-M0+ handles 16-bit PID loops and Modbus RTU framing. The 64 KB Flash holds a FreeRTOS kernel and peripheral drivers.
