Add HDMI connectivity to your Alchitry Au or Pt FPGA setup with this expansion board. It provides two micro HDMI ports for video-related projects and FPGA experiments.
Each HDMI port can be configured as either a source or a sink using solder jumpers, giving you flexibility when building display, capture, or pass-through designs.
The board includes a 5V boost converter plus 5V to 3.3V IO level shifting for the I2C interfaces and hot plug signals on the HDMI ports. It is pin compatible with the Alchitry Ft, but requires an Sp or another board between them to allow room for the USB and micro HDMI cable on port 1.
Features:
- Adds two micro HDMI ports to an Alchitry Au or Pt.
- Each port is configurable as a source or sink via solder jumpers.
- Includes a 5V boost converter.
- Includes 5V<->3.3V IO level shifters for the I2C interfaces.
- Includes 5V<->3.3V IO level shifters for the hot plug signals on the HDMI ports.
- Pin compatible with the Alchitry Ft.
- Requires an Sp or other board between the Ft and this board to fit the USB and micro HDMI cable for port 1.
Specifications:
- HDMI ports: Two micro HDMI ports
- Port configuration: Source or sink via solder jumpers
- Boost converter: 5V
- IO level shifting: 5V<->3.3V
- Level-shifted interfaces: I2C interfaces and hot plug signals on the HDMI ports
- Compatibility: Alchitry Au or Pt
- Pin compatibility: Alchitry Ft
Documentation available for this board includes a schematic and 3D Model (STEP).
Jargon buster
Plain-language definitions for the technical terms used above.
- boost converter
- A boost converter is a power circuit that raises a lower input voltage to a higher output voltage. It matters here because the board can power a sensor that needs a higher supply voltage while still using a single connector for power and data.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
