Features

  • Placement for Acqua A5 SoM
  • All the Acqua lines are available on pads pitch 2.54 mm (100mils)
  • DPI port placement
  • Size 10x10 cm

BERTA-A5-EXT

This board is a step over the BERTA-A5-BASIC providing the basic circuitries to give the power-on and connections to the Acqua A5 SOM maintaining access to the highest number of Acqua pins.

Features

BERTA-A5-LCD Evaluation board

This is an further step to the previous development board adding the supporto for TFT displays size 4.3", 5" and 7" inches with resistive touch

Features

  • Placement for a TFT LCD display size 4.3, 5.0 or 7.0 inches with resistive touch screen
  • Ethernet port at 10/100 Mbps
  • 2 USB 2.0 host hi-speed port
  • 1 USB 2.0 device hi-speed port or USB 2.0 host hi-speed port or placement for a WIFI-2 WiFi module.
  • MiniUSB power in
  • Placement for Acqua A5 SOM
  • All the Acqua lines not used by the on-board components are available on pads pitch 2.54 mm (100mils)
  • DPI port placement
  • Size: 10x25 cm
  • Getting started with Acqua A5 and Berta dev boards

DPI port pinout
