• PCBs in Production

    Andrei V • 08/05/2025 at 05:42 • 0 comments

    I ordered the PCBs last week. The PCBs are ready, today the assembly starts and by the end of the week they should be ready to ship.

    Meanwhile, I also designed a display adapter for a 3.4" display. Due to space constrains, I reduced the display connector to the minimum size possible. This was also because there is not quite a standard display connector. They come in many flavors and sizes. Also the backlight configuration is quite different. Without further adue, I present to you, the display adapter:

    A modest 2 layer flex PCB(with stiffener on the back). This routes all the necessary signals to the display. In addition, has an integrated boost converter to allow a backlight voltage up to 28V and a MOSFET control for the backlight.

    This is for certain Chinese 30pin displays. In the following weeks, I want to develop a 40pin adapter and also a ribbon cable for compatibility with raspberry pi displays.

    Let me know what you think, if you need an adapter for a specific display or other features.

  • Design freeze for NovaCore_v2.0

    The design for the second iteration is done. The PCBs are on hold, waiting for the components to arrive in stock at JLC. The estimate is the end of the month.

    Couple of updates related to the design:

    - SDRAM is length matched(8mm) to achieve the 166MHz top speed

    - QSPI bus to flash is also length matched(8mm)

    - The 8bit bus is also length matched(8mm). I am hoping to get a stable 100MHz => 100MB/s transfer speed

    - LSM6DS016IS IMU will be populated, I can not wait to play with the internal sensor fusion. I aim to get 9DoF quaternions straight out of it(fingers crossed)

  • First iteration validated

    The first iteration of this module validates the MCU. It is different from the current design, but the MCU is validated. It works as expected.
