That is impressive performance. They are nice displays, I tried the same model (identical board to yours) a while back, but with Arduino. However there the SPI code worked without the chip-select (I probably assigned the chip-select to an unused pin, I'd have to check)...
timg236 commentedon Mar 4, 2024 timg236 PCIe2 is RP1 - it is a separate RC and doesn't get re-initialised as part of the boot-order loop. If that fails you would an RP1 not found error. If it didn't attempt to boot from NVMe then either it's missing from the BOOT_ORDER or ...
The 22pin FFC to mini-SAS adaptor board was not included. The picture shows the board part number as 700-55271 REV X3.Is there a way I could buy this board, or could NXP provide the design files including schematic and board layout so I can have one made? Thank you RPI-CAM-MIPI...
It is a little more advanced hack, so it is only really for people who are comfortable with this kind of thing. First, you have to figure out which is the input of the E-Line on your matrix (they seem to be either on Pin 4 or Pin 8 of the IDC connector). You need to disconne...
- Create multiple projects in the app - In each project create a custom control layout using a drag/drop, fill in the blank, graphical interface. Add buttons, switches, lights, etc. - Controls allow you to set GPIO pin state; run Pi commands; play sounds; run macros; display the state...

Layout & Interfaces Block Diagram System block diagram Power CaribouLite draws power through its 40-pin header from the Raspberry Pi’s 5 V rail. Those 5 V are used by the Tx-side RF amplifier after some filtering (full version only). A low-noise 3.3 V LDO is used to supply the board...
Updated Layout •2 × 4-lane MIPI DSI/CSI port, compatible with CSI-2 camera and DSI display•Adapting PCIe 2.0 interface via FPC connector, supports high-speed peripherals•Onboard power button for power on/off without disconnecting power adapter•Onboard RTC battery header for connecting...
Eben has a front-page story up explaining rev 2.0.It does fix the 1.8V problem, although no credit wherecredit is due to Jamodio or any of the others here for finding, characterizing, and reporting the problem.No mention that I can see of FCC/CE resident
