phyBOARD-Wega {#phyboard-wega} ============= The phyBOARD-Wega for phyCORE-AM335x is a low-cost, feature-rich software development platform supporting the Texas Instruments AM335x microcontroller. Moreover, due to the numerous standard interfaces the phyBOARD-Wega AM335x can serve as bedrock for your application. At the core of the phyBOARD-Wega is the PCL-051/phyCORE-AM335x System on Module (SOM) in a direct solder form factor, containing the processor, DRAM, NAND Flash, power regulation, supervision, transceivers, and other core functions required to support the AM335x processor. Surrounding the SOM is the PBA-CD-02/phyBOARD-Wega carrier board, adding power input, buttons, connectors, signal breakout, and Ethernet connectivity amongst other things. There are (for example) some expansion boards available for the phyBOARD-Wega: - Power Module (PEB-POW-01) - Evaluation Board (PEB-EVAL-01) - HDMI Adapter (PEB-AV-01) For further information and instruction please visit: www.phytec.de/produkt/system-on-modules/single-board-computer/phyboard-wega Interface notes --------------- **SPI** Spi0 can be used over pins on X69 connector. There are no more spi-devices. Independent of the given index in mraa_phyboard_spi_init_pre() function, it will be always initialized spi0. **I2C** /* TODO */ **UART** Uart0 can be used over pins on X69 connector or serial port on Evaluation Board. The other Uarts not have been tested yet. This is a small TODO for future.
