IoT Development Kit with Allwinner H3, nRF52840

Droid Technologies designed and developed a custom IoT development kit for connected devices, smart wearables, sensor systems, and embedded product prototyping. The platform combines an Allwinner H3 MPU with a Nordic nRF52840 MCU, providing both high-level processing and low-power wireless connectivity.

The device integrates LTE, Bluetooth Low Energy (BLE), motion and biometric sensors, display and audio interfaces, wireless charging, LPDDR3 memory, and eMMC storage, creating a flexible platform for developing advanced connected products.

Droid Technologies delivered hardware design, PCB development, embedded firmware, embedded Linux integration, wireless connectivity, sensor integration, power management, and complete hardware-software integration.
