One problem that I had is that the power system of this board is setup to take 5V from the Arduino base board but the WICED development kit gives only 3.3v. Here is a picture of the power system from the MBR3 schematic. The MBR3 can run on 3.3Vs. In fact it can run all the wa...
One contact of the relay powers the sensors operating at 3.3 V while the other powers the sensors operating at 5 V. The board was designed using Autodesk's EAGLE software. Figure 4 illustrates the placement of the materials on the board (left) and the assembled board of a node (right...
