The Andino X1 is a microcontroller board for the Raspberry Pi in a DIN-rail housing for installation in a control cabinet in industrial environments. Its built-in Arduino compatible microcontroller is used to adapt digital inputs and outputs for a voltage of 24 V, with the controller ensuring precise signal preprocessing and adaptation of signal generators and actuators. It also contains a Raspberry Pi 4 or 3B+, depending on the configuration. The protection of the inputs and outputs through ridgid connectors, as well as the robust power supply for the Pi and board enable usage in an industrial environment. Communication between the microcontroller and the Pi takes place via the UART interface.

The 40-pin connector is compatible with Raspberry Pi 3B+ and Raspberry Pi 4. This enables easy data processing using our custom software, python libraries and node-red nodes that are purpose-built for a variety of usage scenarios. Since all of our software is based on Raspberry Pi OS, you can also choose from a large collection of software built for the Raspberry Pi and Debian.

The Atmel microcontroller (ATmega 328P) of the Andino X1 comes with an Arduino-compatible bootloader. The combination of Arduino and Raspberry Pi on the X1 is ideally suited for use in home automation and sensor technology, as well as in more demanding industrial automation applications. The strengths of both boards complement each other perfectly. While the single-board computer Raspberry Pi can perform complex tasks (e.g. hosting of databases and WebServers) as a full-value computer, the Arduino microcontroller can take care of the fast signal pre-processing. The Atmel Controller communicates with the Pi via UART. A firmware that can be used for reading input signals, controlling relays and even more advanced options like reading temperature sensors is provided by us and pre-installed on every device on delivery. This firmware is also created to be able to communicate with other Andino hard- and software. A custom firmware can also be programmed using the Arduino IDE via USB from a PC or from a Raspberry Pi.

The X1 board has a 9-24V wide-range DC input with reverse polarity protection. Powerful, reliable, stable power supply: 5 Volt, 2.6 Amp – enough power for the Raspberry, your USB hardware and customer-specific adaptation. The integrated EMC protection circuits protect the Pi from voltage surges and current surges on the supply line. For especially mission-critical projects, the Andino UPS can be used to allow for a shutdown period on sudden power loss, thus preventing data corruption.

The X1 board has two electrically isolated inputs (up to 5kV isolated) as well as two relay outputs for 42 volts and 1 amp. The rest of the Raspberry Pi GPIO Pins as well as IO of the Microcontroller are led on an internal pin header. This makes it possible to bring own adaptations to the screw terminals.

Via the SPI and the I2C interface of the Raspberry Pi, further hardware extensions can be connected and led to the free screw terminals. These extensions are usually sold as one product with the X1 board and a Raspberry Pi. For an overview of all the available versions, please refer to the shop page of the Andino X1.

The integrated, battery-buffered RTC provides the correct time even if no NTP (time) server is available. The high-precision time chip DS3231 from Dallas Semiconductors is used. Due to the internal temperature compensation of the oscillator, the chip achieves a very high accuracy of ± 2ppm at 0 ° C to + 40 ° C.
