Memories
About the Memories PCB
Memories is an open source PCB design by gipi, published on GitHub. It is a 2-layer board measuring 59.9 × 64.3 mm, with 38 components from 14 distinct parts.
Other key parts include the NAND512, AMS1117-3V3 and MT48LC32M8A2. By type, the board carries 22 resistors, 8 capacitors, 3 ICs, 2 connectors and 1 diode.

Here I'm trying to create a header for the Mojo development board that allows to have the basic minimal peripherals for a running system:

In this directory there are the KiCAD files and this is the hand soldered version 1.0
The flash memory under experimentation is the NAND512W3A2C, with 512 Mbit and x8 of bus width.
The SDRAM used here is the MT48LC32M8A2.
