APF27Dev

Description

This is the Armadeus System's standard development board/baseboard for the APF27 module.

The following options are only populated on the "Full" version (APF27DevFull):

• DVI/HDMI
• RTC
• CAN Bus
• ADC/DAC

Errata

• The APF27Dev DVI/HDMI output may not work correctly: due to a hardware issue on the Powerdown pin of the AD9889, the component may not work as expected (display not detected or going to sleep after some minutes).
  • Solution: remove R43 and connect pin PD/A0 (23) to GND. You can place a short circuit over C76.
  • Consequence: the AD9889 can no more be placed in low power mode by hardware.
