 - microSD socket
 - Gateworks System Periperhal Controller
 - front panel LED's
 - front panel pushbutton
 - RS232 connector (2x UARTs)
 - Digital I/O connector (I2C/GPIO)
 - SPI connector
 - u-blox Zoe-M8Q GPS
 - LIS2DE12 Accellerometer
 - TI CC1352 ARM Cortex-M4 multiprotocol sub-1GHz / 2.4GHz wireless MCU
 - On-board brcmfmac WiFi and BT module
 - RGMII RJ45 GbE
 - 1x MiniPCIe socket with PCIe/USB 2.0
 - 1x MiniPCIe socket with USB 2.0 and nanoSIM socket
