In reality, not much tweaking was required from the alpha design. The biggest changes are:
- inclusion of Electrostatic discharge (ESD) protection for the USB plug
- replacement of certain PMIC inductors that were found to be extremely fragile
- changes in the gold plating deposit pads to improve the quality of the USB connection
Additionally, we tested the standalone USB host mode using a Mimo UM-720F USB monitor. As you can see, the monitor, along with a powered hub, keyboard, mouse and WiFi adapter, are perfectly functioning with the USB Armory host mode described in the first update.
