MCU and Motor Driver Leaf Modules of Coin-Sized PCBs in an Open-Innovation IoT/CPS Platform

One trillion IoT nodes will be in use in the 2030s. To realize the rapid penetration, development platforms, where IoT devices are easily prototyped, are required. We present the platform where IoT devices are realized selecting and connecting several single-function PCBs. Moreover, we have developed a 58-pin connection mechanism by rubber connectors and have realized a 32-bit high-performance MCU PCB module, which requires many pins for its multiple functions. We have also realized a motor driver PCB module, which mounts a wire connection mechanism where wire connection to motors is realized without soldering. These modules enable us to prototype our own IoT devices with wireless communication PCB modules and/or camera PCB modules. The proposed platform provides Jisso technology for everyone to prototype own IoT devices easily.
