Dev Kit Weekly: STMicro's STM32U5 NUCLEO-144 Evaluation Board
On this episode of Dev Kit Weekly, we’re going over the STM32U5 NUCLEO-144 evaluation board from STMicroelectronics.
If you’re a prototyper working on something like an IIoT sensor module, it’s easy to get overwhelmed by all the intelligence, power-efficiency, connectivity, security, and safety components your design will require.
Fortunately, ST has a life raft for Industrial IoT prototypers in the form of STM32U5 NUCLEO-144 evaluation board.
The STM32U5 portfolio is a family of extreme low-power secure microcontrollers designed around a 160 MHz Arm Cortex-M33 CPU with a single-precision floating point unit, DSP instructions, a memory protection unit, and a bunch of specialized math, imaging, and crypto accelerators.
All of that is enough to efficiently capture and analyze sensor readings at the edge even if you’re running on a battery or other limited power supply because STM32U5 devices draw just 110 nA in shutdown, 300 nA in standby, and as little as 19 µA per MHz in active mode.
Those double-take-inducing power consumption numbers are possible thanks to innovative new features on the STM32U5 like low-power background autonomous mode (LPBAM) that are especially relevant for local sensor monitoring, as it lets peripherals like sensors and ADCs continue operating even when the CPU is asleep.
All it’ll cost you is a cool $22.54 per unit — not bad at all. But as always, you can enter the raffle to test your luck and win the board we looked at today, and we’ll ship it to you anywhere in the world for free.
