Multimedia Shield for Alhambra-II
actual photo

This board is intended to be connected into the expansion pins of an Alhambra-II FPGA board, and it provides it with:

VGA video output, 2-bit per color component (64 colors) Compatible with (AP-VGA)
Audio output. 1-bit input (for PWM or Sigma-Delta signals) with active analog low-pass filter. Capable to drive headphones
Audio input. Second order analog sigma-delta modulator with 10+ effective bits of resolution and 20kHz bandwidth
PS2 keyboard connector with 5V level shifter
USB connector
micro-SD card connector (SPI mode)
8MByte, Quad-SPI, PSRAM

Due to the limited number of pins the PS2 and USB interfaces share their signals and can't be used at the same time. The same happens with the SD card and the PSRAM. Also, in this later case the Alhambra's I2C ADC can't be used.
