Qwiic LTE CAT M1/NB-IoT Shield - IoT shield with LTE SARA-R4 modem for Arduino + SIM card

Multifunctional expander (shield) for NUCLEO and Arduino equipped with Bluetooth 2.0+EDR (HC-05) interface, MEMS 3DoF LIS35, LED-RGB, joystick and analog STLM20 temperature sensor developed and produced by KAMAMI.

The CAN-BUS Arduino Shield v2.0 can be stacked on an Arduino UNO, Arduino Leonardo or Arduino MEGA board. The shield integrates an MCP2515 CAN-BUS chip on the shield and has a CAN-BUS transceiver function. With an on-board DB9 and CAN-BUS connector you can choose a suitable port according to your host device. There is also an integrated MicroSD socket for data storage. DFR0370
