Recommended Hardware
Motor control on Nordic targets typically pairs the Nordic MCU (handling wireless telemetry, configuration, and OTA) with a dedicated motor-driver IC and external CAN/CAN-FD controller over SPI when CAN is required.
nRF52840
Advanced multiprotocol SoC with 1MB Flash, 256KB RAM, and USB support. Drives the wireless, configuration, and telemetry plane while a dedicated motor-driver handles the high-frequency current loop.
nRF5340
Dual-core Bluetooth 5.4 SoC with dedicated application and network processors. Provides headroom for FOC supervisory control alongside BLE telemetry and OTA updates.
Environmental Monitor
Multi-sensor environmental monitoring station that measures temperature, humidity, air quality, and pressure, reporting data wirelessly to a central system.
Predictive Maintenance Sensor
Vibration and temperature sensor for industrial equipment monitoring, detecting anomalies early to prevent costly downtime and failures.
