I want to introduce a new project by me - PiMKRHAT. The PiMKRHAT is an adaptor to use Arduino MKR boards and shields together with the Raspberry Pi. Different Arduino MKR Shields can be used via this HAT as extension for the Raspberry Pi. Furthermore Arduino offers different Arduino boards for different IoT networks like Sigfox, Lora, NB-IOT. These boards can be used like a modem via the serial interface of the Raspberry Pi as extension to communicate with these wireless standards.
