1
Procurement & Preparation
- Procure and inspect the Pico-ITX carrier board PCB and all Bill of Materials components including SOM-1844L, LT8640SEV#PBF, LT6911C, FH28D-50S-0.5SH(05), and LBEE5QD1ZM-572.
- Prepare SMT stencil, lead-free SAC305 solder paste, and setup pick-and-place machine coordinates for the Pico-ITX carrier board layout.
2
Hardware Assembly & Wiring
- Apply SAC305 solder paste to the PCB pads using the SMT stencil and verify paste volume with 3D SPI (Solder Paste Inspection).
- Place surface-mount components including the LT8640SEV#PBF power regulator, LT6911C HDMI bridge, FH28D-50S-0.5SH(05) camera connectors, and LBEE5QD1ZM-572 wireless module onto the board.
- Pass the populated board through a multi-zone reflow oven using a standard lead-free thermal profile, followed by automated optical inspection (AOI).
- Manual hand-solder or press-fit the board-to-board connectors and mount the NXP i.MX 8M Plus System-on-Module (SOM-1844L) onto the carrier board.
3
Firmware Setup
- Connect a USB-to-UART debug cable to the carrier board debug header and configure a host terminal emulator at 115200 baud.
- Flash the customized U-Boot bootloader, Linux kernel, and device tree (DTB) supporting the i.MX8MP, TC358767XBG/PTN3355DP HDMI bridge, and IW612 wireless driver into the SoM eMMC storage.
- Configure the Linux kernel device tree to enable the dual MIPI-CSI camera interfaces, SDIO wireless stack, and DSI-to-HDMI display output pipeline.
4
Testing & Calibration
- Apply a 12V-24V industrial DC supply to the power input terminals and verify output regulation of 5V and intermediate rails using a digital multimeter.
- Test the display interface by connecting an HDMI monitor and verifying output initialization via the LT6911C bridge and i.MX8MP MIPI-DSI interface.
- Verify dual MIPI-CSI camera capture pipelines by connecting test camera modules to FH28D-50S-0.5SH(05) connectors and streaming live video frames.
- Perform wireless functionality tests by scanning for local Wi-Fi networks and pairing Bluetooth devices through the LBEE5QD1ZM-572 module.

System Architecture
Power Topology: Industrial 12V-24V input passes through SMCJ30CA TVS diode and reverse polarity MOSFET, then steps down to a clean 5V intermediate bus using a TI LM5164 / LT8640S synchronous buck converter. Point-of-load LDOs and regulators on the SoM and carrier board distribute 3.3V, 1.8V, and core rails.
