Modify Connector in PCB Design
Thought for 17 sec
Tôi sẽ kiểm tra xem dự án gốc
lamthientieu/esp32 còn truy cập được không; nếu đọc được, tôi sẽ dùng nó làm nguồn để phục dựng/thay J_DWIN. Nếu không đọc được, phương án còn lại là dựng thủ công từ Gerber/BOM và cần bạn xác nhận connector 1.0 mm muốn dùng.Thought for 2 mins 36 sec
Không cần import
.flx nữa. Dự án gốc vẫn còn mở được tại:Cách đúng nhất là:
- Mở link trên.
- Vào menu góc trái.
- Chọn Clone Project.
- Clone về tài khoản của bạn.
- Sau khi clone xong, gửi tôi link project clone đó — tôi sẽ sửa trực tiếp
J_DWIN.
Tôi đã đọc được dữ liệu dự án gốc:
J_DWIN hiện là FFC2B35-10-G, 10 pin, pitch 0.5 mm. Pin quan trọng:- Pin 1–3:
5V - Pin 5:
DWIN_RXD - Pin 6:
DWIN_TXD - Pin 8–10:
GND
Sau khi bạn clone được project, tôi sẽ thay connector sang loại 10 pin pitch 1.0 mm hoặc tạo footprint custom nếu thư viện chưa có đúng part.
Yes clone project
Need cloning steps
Use connector MPN
Fix directly after clone
Manual rebuild option
No schematic yet

Key findings
- The Gerber package identifies the source project as Esp32, version
#dc4b03ef, original URLhttps://www.flux.ai/lamthientieu/esp32~zu. - The current project started empty, so there was no existing schematic or PCB to directly modify.
- The
.flxfile appears to be a Flux project export. It is intended to be re-imported/opened through Flux project import/open workflow, not treated as an EDA library part import. - The EDIF file could not be searched successfully by the file reader in this session, so a complete schematic-level netlist was not available from it.
- The Gerber ZIP contained a BOM, pick-and-place, Gerbers, drill file, and IPC-D-356 file. It provided enough information to identify several components and confirm the J_DWIN footprint, but not enough to safely recreate the complete schematic with all electrical nets.
J_DWIN connector
Original BOM entry:
- Designator:
J_DWIN - MPN:
FFC2B35-10-G - Manufacturer: GCT
- Description: 10-position FFC/FPC connector, bottom contacts, 0.50 mm pitch, surface mount, right angle
IPC-D-356 pad pitch analysis:
- Signal pads 1–10 are spaced by about 197 IPC units.
- With IPC-D-356 scale of 0.0001 inch/unit, this equals about 0.500 mm pitch.
- Therefore the existing design really uses a 10-pin 0.5 mm FFC/FPC connector.
Estimated 1.0 mm pitch pad centers if kept around the same footprint center:
- Pin 1:
X-000903Y+024705 - Pin 2:
X-000509Y+024705 - Pin 3:
X-000115Y+024705 - Pin 4:
X+000278Y+024705 - Pin 5:
X+000672Y+024705 - Pin 6:
X+001066Y+024705 - Pin 7:
X+001460Y+024705 - Pin 8:
X+001853Y+024705 - Pin 9:
X+002247Y+024705 - Pin 10:
X+002641Y+024705
Library search status for 10-pin 1.0 mm FFC/FPC
- Exact 10-position, 1.0 mm pitch, right-angle, bottom-contact FFC/FPC connector was not found in the Flux library during this session.
- Closest 1.0 mm part found:
FH12-8S-1SH(55)— correct pitch/family/style but only 8 signal positions, so it is not a valid replacement for a 10-pin DWIN cable. - A 12-position 1.0 mm Molex part appeared in one search, but it is not a 10-pin connector and would change cable/mechanical compatibility.

Blockers before safe reconstruction
- The current project is empty and the
.flxexport has not been imported into the active project by the platform workflow. - Complete schematic connectivity could not be extracted from the EDIF file in this session.
- The exact 10-pin 1.0 mm FFC/FPC connector is not currently available in the Flux library search results.
Recommended next step
Import/open the
.flx export into Flux using the project import/open workflow first. Once the design is actually present in the project, replace J_DWIN with an exact 10-pin 1.0 mm FFC/FPC part if available, or create/import a custom part/footprint such as Hirose FH12-10S-1SH(55) or another confirmed 10-position 1.0 mm bottom-contact FFC/FPC connector.Source files reviewed
