We love the Alorium Technology Snō Development Board! Alorium have done a really great job in integrating an ATmega328-compatible core into the FPGA, which you can then program from the Arduino IDE and access the features of a Verilog Xcelerator Block (XB) from normal Arduino code.

You can of course use an HDMI breakout board or cable to connect the Snō’s pins to your monitor. But why not do the job properly and equip your Snō with a Snō Shoe?! The Snō Shoe will make life easy for you. It provides:

• A full-size HDMI socket connected to four pairs of (differential) FPGA pins
• A Qwiic I²C connector so you can easily attach your favourite SparkFun Qwiic boards
• A USB-C socket for power, configuration and Serial communication
• A CH340E USB interface, so you don’t need to use a separate FTDI breakout to configure the Snō
• If you want the Snō to be removable afterwards, you could use break away pins on the Snō and female headers on the Shoe. The Snō Shoe has been designed so you can mount the Snō on the top of the Shoe, or underneath, depending on your preference. A reset button and I²C split pads are accessible in both configurations. Long Break Away Headers should allow you to connect some of the breakout pins to standard breadboard.
