Field Terminal V2 - Custom Rugged Cyberdeck

This is my custom design for a mobile terminal (Cyberdeck) built primarily for penetration testing (Kali Linux) and field work. The device is rugged, features active cooling, and packs a massive 14,000 mAh battery, allowing for over 12 hours of continuous operation.

Bill of Materials (BOM):
Electronics (Core):

SBC: Raspberry Pi 3B+ (USB ports were desoldered to slim down the casing. SSD controller is soldered directly to the PP test pads underneath).

Display: Waveshare 4.3" DSI LCD (800x480).

Keyboard: Rii mini X1 (Bluetooth/2.4GHz version).

Storage: mSATA or M.2 SSD (using a USB adapter stripped of its plug).

WiFi: USB WiFi adapter (e.g., Realtek RTL8812AU chipset) + SMA Pigtail + 5dBi Antenna.

Power System:

Cells: 4x 18650 cells (e.g., Samsung 35E) connected in parallel (1S4P).

Charging/Boost Module: Based on IP5310 or IP5219 chip.

NOTE: Due to the high inrush current of the Raspberry Pi at boot, an NTC 5D-9 thermistor was soldered in series with the power line (+5V) to prevent the module from triggering short-circuit protection and cutting power.

Switch: Rocker Switch KCD1 11x15mm.

Charging Port: Panel-mount USB-C socket.

Cooling:

5V Fan 30x30mm

Mounting Hardware:

Brass Heat-set inserts (M2.5 and M3).

M2.5 and M3 screws (various lengths, countersunk head recommended).

Tesa fabric tape (automotive harness tape) for cable management and rattle prevention.
