Exposed signals

  • J4 Placement for a 20x2 pins connector pitch 2.54mm (100 mils) (pinout):
    • 1 full-speed usb host
    • 1 hi-speed host/device (same port lines used for the microUSB port)
    • 1 hi-speed host (same lines used for the WiFi adapter)
    • UART lines: 3 ports
    • I2C bus lines: 2 bus
    • SPI bus lines: 1 bus with up to 3 chip select (5 to 50 MHz)
    • PWM lines: 4 lines
    • A/D converters lines: 4 channels@10 bit
    • SSC/I2S interface for audio soc
    • No video or TFT output but the SPI bus can be used for small TFT display and I2C bus for small alphanumeric LCD
    • No direct LAN interface but the USB ports can be used with USB to LAN adapter
  • DP placements for a 6 pin male strip pitch 2.54 (100 mils) with the Debug Port Interface lines
  • Placement for IEE802.11 b/g/n Wi-Fi module WiFi USB adapter

Please note that not all the signales are available at the same time. Some line are muxed together.

Pin muxing

Most of the Arietta lines on J3 can be configured for additional functions using the muxing cabability of the Atmel MPU. The default configuration depends from the at91-arietta.dtb file stored on the first micro SD partition and used at startup by the Linux Kernel.

The Arietta dynamic pinout page may helps you to understand what are the available peripherals and how to generate this file.

Software features

  • This board is fully supported inside the Linux Kernel main stream http://www.kernel.org. Thanks to this fact it is possible to try also the very latest Kernel releases. On this site we'll release up to the latest longterm versions.
  • All the kernel drivers are fully open source and available directly on the official Linux repository.
  • On the main index is available the step-by-step documentation to install Linux from scratch.
  • Ready-to-use binary images are available on the download page
  • Ready-to-buy-and-use microSDs are also available on our Acme Systems eShop
  • Thousands of open source applications are available from the Debian and Buildroot repositories.
  • ARMHF is the architecture to select for RoadRunner and Acqua boards. ARMEL is the architecture to select for Aria and Arietta boards.

Please note ! Starting from July 2018 we make by default just color green Ariettas G25. The only difference between the legacy black version (ARIETTA-G25) and the new green version (ARIETTA-G25-V) is the solder mask color. To order the legacy black version a Minimal Quantity Order of 100 pcs is requested.
