Geekworm X635 HDMI to CSI-2 & M.2 NVMe/SATA SSD Carrier Board for Raspberry Pi CM4

Overview The X635 is an ultra-compact carrier board specifically designed for the Raspberry Pi Compute Module 4 (CM4). It integrates an M.2 NVMe SSD expansion interface and an HDMI-to-CSI-2 bridge, making it ideal for video capture, storage expansion, and embedded applications requiring HDMI video input. The onboard TC358743 chip converts HDMI video streams into MIPI CSI-2 TX signals, allowing the CM4 to receive HDMI video input through its CSI camera interface. Features Designed for Raspberry Pi Compute Module 4 (CM4) Compatible with all Raspberry Pi CM4 variants HDMI to CSI-2 bridge for HDMI video capture applications TC358743-based HDMI Full HD capture solution Supported HDMI input resolutions: 1080p30 / 1080p25 720p30 / 720p25 Supports HDMI audio capture via I2S M.2 2242 Key-M socket for NVMe SSD expansion Supports booting from Micro SD, eMMC, and NVMe SSD Gigabit Ethernet port with PoE expansion support Mini HDMI output supporting up to 4K display USB 2.0 Type-A port for CM4 eMMC programming and USB expansion USB Type-C power input 26-pin GPIO expansion header Compact size: 55 × 70 × 18 mm Notes Raspberry Pi CM4 module, Micro SD card, SSD, and power supply are NOT included. Do NOT power the X635 through the USB Type-C port when it is connected to a PC via the USB Type-A port. To enable CM4 programming via rpiboot, place a jumper cap between the nBOOT and GND pins on the 6-pin header. Please use only the included M2x3mm SSD mounting screws. Screws longer than 3mm may damage the Micro SD card or card socket. How to Power Power the X635 via the USB Type-C 5V input. If the USB Type-A port is connected to a PC, the PC USB port will supply power to the X635. Do NOT connect an additional power supply to the USB Type-C port while connected to a PC via USB Type-A. Cooling Solution For better thermal performance, the X635 can be used together with the C235 aluminum heatsink designed for Raspberry Pi Compute Module 4.
