以下是GPT-5.6 Sol针对官方开发板给的改进建议。
洋洋洒洒11页,还发现了一些官方板的问题:
The recommendations below apply to the official EPC9192KIT and are not claims about changes already implemented.
Before modifying hardware, resolve these documentation and assembly questions:
1. EPC9558L C3 is 100 pF in the BOM, while the schematic note says 82 pF is mounted in CH1. Record the actual value on both modulator boards.
2. The EPC9192 BOM marks the Allegro ACS71240 current sensor position as empty and the MPS MCS1823 position as populated, while the guide describes the Allegro part as the default. Confirm whether each channel has a nominal 40 A or 45 A OCP threshold.
3. Confirm the actual L2 part. The documentation variously describes it as 14 A, 40 A peak, or greater than 40 A saturation current.
4. Record the population of EPC9558P D1-D4, R86, L1, L2, and all parts marked `EMPTY` in the BOM.
5. Record all PCB, schematic, BOM, and assembled-board revision labels. The supplied documents mix Rev. 1.0, Rev. 2.0, and Rev. 2.1 identifiers.
