Adding LTE Modem and other USB devices

[lykso]

Looks great! I’m going to try a slight variant of this mod once the following components arrive:

• Koutech USB 2.0 Header-Pin to Dual Type-A Adapter

• Industrial-Grade USB2.0 Expansion Module (Cheap on Amazon, but even cheaper on AliExpress if you’re willing to wait a couple months for it to arrive.)

• Davitu Electrical Equipments Supplies - 50Pcs PH 2.0mm Right-Angle JST Socket Male Connector (Pins: 4P)

• Ratchet Crimping Tool Kit, Self-adjustable Wire Crimper Plier Set Crimping tools Kit With With 920PCS Connectors Include JST PH 2.0 and JST XH 2.54 Terminals

I already have these parts on hand and not being used for anything at the moment:

• Huawei E3372

• A 9-pin USB header cable for connecting to the 2 USB port board. Could not use this, in the end. Made my own with a Dupont cable kit.

• RobotDyn - USB to TTL UART CH340 - Serial Converter Adapter, Micro USB, 5V/3.3V. IC CH340G (Will require modifying the UART mount in the OpenSCAD model.)

Will check in again after my parts arrive sometime between mid-October to mid-November and after I get a chance to try the mod.
