Hi Everyone, Thank all participants of the meeting about the NuttX Standard Board.
For those who were unable to attend, the video is available on YouTube: https://www.youtube.com/watch?v=keZAZ8GiYzI Just a summary of our meeting today: - It was defined that we should use the DIMM DDR2 SO-DIMM. Pros: It has 200 positions (pins); Low Cost; Easy to solder manually; The CPU/MCU Modules don't require a connector. Cons: the CPU/MCU module needs to use ENIG ( https://en.wikipedia.org/wiki/Electroless_nickel_immersion_gold) that is a little bit more expensive than simple PCBs - In order to simplify the base board routing and avoid complexity some high speed interfaces (LCD, Ethernet) will be in the CPU/MCU Module. (but the signals will be available in the connector (TBD)) Pros: Simplify the board design; Avoid rigid rule of have only a single Ethernet's PHY or LCD module tested all the time; Cons: The CPU/MCU Module will end-up becoming more expensive because these extra components - The Mainboard/Baseboard will have the most common sensors/peripheral soldereds in the board and an expansion connectors (i.e. MicroBUS, P-MOD, MicroMOD, etc) to let users/developers test other devices. Pros: Reduce final cost; Brings more flexibility Cons: Increase the board size to support these expansion connectors. We should have a new meeting next week (Sunday) to decide which devices we will include in the board, if you have suggestions to improve our board, please participate.
