The project consists of a case (8 parts) and a board (1 part) for the electronics.
The case is made of coloured PCB material and consists of the “front” (Gerber_Front_20200228004727), 6 pieces of the “wall” (Gerber_Wall_20200228004853) and the “backplate” (Gerber_BackPlate_20200228005103). The front is soldered to the 6 wall pieces to form the “cover”. Pin headers (2×1) are used to keep the cover and the backplate together. The backplate has 4 soldered nuts (or SMTSO standoffs) to hold the board and 2 pin header connectors (4×1) for the sensor. The case will be available in 2 colours for 2 models. One model is white. Another model is black.
The board (Gerber_ONE-iP_20200228005251) is entirely with THT components. A female pin header connector (4×1) is at the bottom. The rest of the components are on the top side. 2 interchangeable power supply components are used to produce 2 models of the same PCB depending on region (US, EU).
