Project Properties

This project is made public for the first time and is my original project. The project has not won any awards in other competitions.

Project Progress

Schematic design: Completed.

PCB Design: Completed.

Welding Assembly: Completed.

Basic function debugging: Completed. (Power supply test and crystal oscillator frequency test, network port, USB, serial port, HDMI, TF-CARD)

Design Principles:

Power supply part: The power supply solution uses EA3059, 4-channel 2A-DC-DC, to improve the integration of the power supply part.

Note: Select the necessary parameters when placing an order for proofing. The board material is FR-4, 6-layer board, 1.6MM board thickness. For impedance control, choose JLC06161H-3313 impedance structure. The impedance control error is 20%. For other things, just choose the default parameters. The proofing rules for this board It supports free proofing of JLC6 laminates. FLASH storage, EMMC part. If the EMMC used is emmc5.0, you need to solder the R45 and R46 pull-down resistors. For other types of EMMC, these two resistors do not need to be soldered. The memory particles must use DDR3L and the total capacity does not exceed 2GB (exceeding the limit will not be recognized). The on-board filter capacitor must be an MLCC capacitor, and ceramic capacitors cannot be used, otherwise it will easily lead to unstable operation and crash. The main frequency crystal oscillator of ZYNQ is an active crystal oscillator. Please do not use passive crystal oscillator. Please note that the power supply chip must use EA3059 instead of EA3059C. EA3059C only has 3 DC-DC channels.
