The Rico Board is an excellent high-performance Single Board Computer (SBC) using the newest TI’s AM437x Sitara ARM Cortex-A9 based solution. This new generation solution has an increase in performance, as well as extensive reuse from the ARM Cortex-A8 offerings. It features up to 1GHz of processing power, 3D graphics acceleration for rich graphical user interfaces, PRU-ICSS for industrial protocols, improved Vector Floating Point (VFP) unit and other peripherals and interfaces support like Quad-SPI, dual parallel cameras, two independent eight-channel ADCs, etc.

The AM437x processor family has four different pin-to-pin compatible AM437x device variations: the Sitara AM4376, AM4377, AM4378 and AM4379. They only have differences in options whether they have offered 3D graphics accelerator and their PRU can support for the EtherCAT slave protocol. Users can make selections according to their requirements.

The Rico board is equipped with 512MB DDR3, 4GB eMMC Flash, 16MB QSPI Flash and 32KB EEPROM on board. Additionally, it has rich peripherals including a Debug serial port, USB 2.0 Host and Device ports, a Gigabit Ethernet port, TF card slot, HDMI port, dual camera interfaces, LCD interface, etc. Two 2.54mm pitch 40-pin expansion connectors allow the availability of more I/Os for peripheral signals like two SPI, two I2C, two CAN, four UARTs, one MMC and eight-channel ADC.

The Rico Board is capable of running Linux operating system and provided with Linux 4.1.18 SDK of which the kernel and many drivers are in source code. MYIR also offer a complete Rico Board development kit that includes a Rico Board, necessary cable accessories, an optional 7-inch LCD Module (including capacitive touch screen), optional WiFi and Camera modules as well as detailed documents to enable rapid development when customers getting the board out-of-the-box.

The Rico Board can be used for the evaluation module (EVM) for the AM437x processor family; it can also be used directly for your embedded products. Typical applications are industrial automation, Programmable Logic Controllers (PLCs), bar code scanners, portable data terminals, test and measurement, patient monitoring and human machine interface (HMI).
