Compute Modules and Carrier Boards

10 Lektionen in dieser Stufe

1. Compute Module 4 and 5: Variants and Trade-Offs
   Choose a module by memory, eMMC, wireless and availability. · Lab: Select a module variant for three product briefs and justify each choice.
2. Flashing eMMC with rpiboot
   Put a module into USB boot mode and write an image to its eMMC. · Lab: Flash Bookworm to eMMC from another computer and boot the module on the IO board.
3. Learning from the Reference IO Board Schematic
   Read a reference design and identify what your product needs from it. · Lab: Mark up the reference schematic: keep, change or delete for each sheet.
4. Schematic Capture for a Minimal Carrier in KiCad
   Draw a carrier with power, USB, Ethernet, debug UART and a GPIO header. · Lab: Capture the schematic for a minimal carrier and pass the electrical rules check.
5. Power Tree Design: Input Protection, Regulators and Sequencing
   Plan rails, currents, protection and power-up behaviour. · Lab: Draw a power tree from a 12 to 24 V input to every rail with current budgets and fusing.
6. Routing High-Speed Pairs: USB, HDMI, PCIe and Ethernet
   Apply impedance, length-matching and return-path rules. · Lab: Define stack-up and differential pair rules and route one USB pair and one PCIe lane.
7. Device Tree and config.txt for a Custom Carrier
   Describe your board's peripherals so the kernel configures them. · Lab: Write an overlay that enables your carrier's UART, I2C devices and status LEDs.
8. Antennas, RTC Backup and Wireless Options on Modules
   Select internal or external antennas and plan timekeeping. · Lab: Switch the module to its external antenna and compare signal strength inside a metal case.
9. Board Bring-Up: A Step-by-Step Power-On Plan
   Power a new board in stages without destroying it. · Lab: Write a bring-up checklist and run it on the IO board using a current-limited supply.
10. Design for Manufacture, Test Points and Assembly Files
    Prepare fabrication outputs and make the board testable. · Lab: Generate Gerbers, a bill of materials and placement files and review them against an assembler's rules.

Abschlussprojekt
