The 4ZeroBox is a modular hardware electronic unit that simplifies the development of Industrial IoT applications allowing rapid integration with sensors, actuators, and Cloud services.
4ZeroBox mounts a powerful ZM1 module by Zerynth (240MHz, 16Mb of Flash, 312Kb SRAM) and provides many onboard features like: a DIN-rail mountable case with industrial grade sensor channels, support for Wi-fi, Bluetooth, Ethernet, LoRa, CAN, RS485, RS232, SD Card, JTAG, I2C, SPI; last but not least, there are 2 on-board MikroBUS sockets to extend the 4ZeroBox with hundreds of MikroElektronika click boards (see “MikroBus Slots” section).
In windows it may be necessary to install USB drivers. You can find them here.
