Recommended Hardware
Multirotor flight controllers on Nordic targets typically use a dual-MCU architecture — a Nordic nRF SoC for BLE/cellular telemetry, ground-link RC, and OTA, paired with a dedicated high-rate flight-control MCU on the same board.
nRF52840
Advanced multiprotocol SoC with 1MB Flash, 256KB RAM, and USB support. Drives the BLE/Thread telemetry link, ground-station UART, and OTA updates alongside the flight-control coprocessor.
nRF5340
Dual-core Bluetooth 5.4 SoC with dedicated application and network processors. The application Cortex-M33 has the headroom needed for sensor fusion and supervisory flight modes alongside BLE telemetry.
Medical Wearable
Clinical-grade wearable device for continuous health monitoring including ECG, SpO2, and body temperature, with secure data transmission to healthcare systems.
Point of Sale Terminal
Compact payment terminal with secure element integration, NFC/contactless reader, display, and cellular/WiFi connectivity for mobile commerce.
