Tier 2
ST Nucleo-F446RE
The compact Cortex-M4 board: a quarter of the H753's RAM -- useful for testing tier-2 minimums, not the flagship capacity story.
What it can sense
| Signal | Support | Notes |
|---|---|---|
| Motion | Supported | Module |
| Sound | Limited | Module + 128 KB is tighter than nano33ble/nrf52840dk's 256 KB |
| Sensor values | Supported |
Before you choose it: setup on your computer
No admin needed: copy the firmware file onto the board's USB drive (NOD_F446RE).
- Copying a .bin onto the NOD_F446RE USB drive flashes the board with no driver, udev rule or root (verified 2026-10-01).
- The command-line st-flash route is faster but needs the stlink udev rules on Linux, which the stlink-tools package installs.
Checked on the real part
On 1 October 2026 we generated a reference model for this board and ran it on the board itself. It gave the same answer as our server on 32 of 32 test windows.
