About the Hx8k breakout extension

Hx8k breakout extension is an open source PCB design by maikmerten, published on GitHub under the MIT license. It is a 2-layer board measuring 44.2 × 65.3 mm, with 23 components from 10 distinct parts.

Other key parts include the AS7C34096A-TSOP. By type, the board carries 12 resistors, 5 connectors, 2 switches, 2 diodes, 1 IC and 1 capacitor.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

A PCB with SRAM, buttons, LEDs and some pmod-compatible connectors for the Lattice HX8K Breakout Board

Please notice: This PCB only carries SRAM with a data bus width of 8 bits. This is pretty narrow and can be performance-limiting. Also, let's be honest, this PCB layout is somewhat wacky. Perhaps you might consider building a more recent design with 16-bit SRAM instead.
