The Healthypi move is composed of two primary boards: the main board and the sensor board. The sensor board houses all the essential sensors required for data acquisition and provides the necessary output ports for connectivity. The main board and the sensor board are stacked together along with other components and placed inside the enclosure.

Main Board

The Healthypi Move houses a Nordic nRF5340 dual-core SoC, which has a Cortex-M33 application processor and a Cortex-M33 network processor. It also includes a 128MB flash memory, USB C port for data, charging and SWD debugging and power manager IC.

Sensor Board

The Healthypi Move sensor board is packed with sensors to monitor a wide range of biometric signals. The main board and sensor board are electrically connected together by an FFC cable and FFC connectors. This also opens up the possibility of modifying the device by adding more sensors or changing the sensor configuration.

Display

The Healthypi Move display is a 1.2" AMOLED display with a resolution of 390x390 pixels. This is a full color display which is very bright. The display is flush mounted with only the display sticking out and is held in place using a 3D-printed "display holder".

Enclosure

The main body of the enclosure is a (near) crystal clear Vacuum Casted polycarbonate. This makes up the main top hollow body for the display and everything else that stacks below it, the arms which hold the two pieces of the strap on either side, and the side cutouts for the button and USB-C port.

All the components together from the top display assembly to the main PCB, the battery, and the sensor board (in that order) are held together using a single-piece object made of 3D-printed ABS, inter-structure assembly. This gives strength and rigidity to the entire assembly and also makes it easy to assemble and disassemble.
