OpenMote hardware is composed of three boards, OpenMote-CC2538OpenBase and OpenBattery. On the one hand, OpenMote-CC2538 is the mote itself, including the microcontroller and the radio transceiver, as well as other peripherals such as LEDs and buttons. On the other hand, OpenBase is the board that allows to program and debug the OpenMote-CC2538, as well as to interface it with a computer through a UART or USB interface or with the Internet through an Ethernet port. Finally, OpenBattery is the board that lets OpenMote-CC2538 run autonomously by providing energy to all its subsystems, as well as to interface it with various sensors. You can find more information regarding each board in the corresponding subsection of the Hardware menu or by clicking in the appropriate hyperlinks.
