The Gateway is equipped with 5 RGB user LEDs. 4 are mounted directly to the board, and the fifth is next to the not-programmable blue power LED on the PSU board.

The Open IoT Gateway contains a tactile switch mounted to the PSU board, which can be programmed directly in the MCU.

The Gateway has 4 RS232/RS485 sockets depending on the version.   P10 (4x RS232) The P10 gateway is equipped with 2x ST3232BTR to ensure transmission in RS232 standard. P11 (4x RS485) The P11 gateway is equipped with 2x MAX481CSA to ensure trans...

The Ethernet interface is provided by the IP101G physical layer. An external board with an RJ45 socket ensures a wired connection to the network.

MicroUSB ensures access straight to UART interface (UART4). The Open IoT Gateway does not have inbuild FTDI converter so an external USB to UART FTDI converter is needed to run a serial port monitor on a PC.

The Open IoT Gateway has a built-in Serial EEPROM with a secure element connected to the STM32 via I2C bus.

The Gateway has a Serial flash memory which can be programmed via SPI.

There is a possibility of connecting peripheral I2C sensors. The board has dedicated pins for soldering devices. Below is a proposal for additional sensors that match the hardware. LSM6DS33 - 3D accelerometer and 3D gyroscope LIS3DH - 3-axis "nano"...

Link to repositories: C This example uses UART4 in the MCU which is reserved for the USB UART communication. A simple string is printed on the console and then the device restarts after 10 seconds of countdown. Use 115200 baudrate.

Link to repositories: C A simple blinking LED example intended for the Open IoT Gateway. Lighting LED will be changed every 1 second from LED1 to LED5.

Link to repositories: C Simple tactile switch example intended for the Open IoT Gateway. After flash, connect device to a PC and open port in Console Terminal. The information about the switch pressed state will be displayed in the console as shown b...

Link to repositories: C This script tests internal communication between serial ports with the possible lowest (2400) and highest (115200) baudrate.  For this example, connect each port's transceiver with the receiver: Default settings: baud r...
