Differ from the IDC through the board, cross at 90° to minimize capacitance between traces - .3mm for non-power lines, .6mm if carrying power MK uses a CA3080 OTA, an expensive and rare chip these days ($3/ea on amazon, maybe fakes) VCA MK's VCA Probably a straightforward build: one op-amp, four transistors and some example modules f80e4975fb checkpoint before trying to add picture From 81f5cdc2cd0ea2f7c6a63827426db16f9b2cd3fd Mon Sep 17 00:00:00 2001 Subject: [PATCH 13/18] Add footprint items for panel holes; separate panel and pcb into different files Add footprint items for panel holes; separate panel and pcb into different files Add a front-panel PCB Subject: [PATCH 07/18] Add ground fills, fix some clearance issues, add PCB slot, more options for potentiometer spoke placement Fix rail clearance issues, make all power traces large main VCA/Schematics/Dual_VCA_with_cv2.diy 8684 lines master PSU/Synth Mages Power Word Stun.kicad_sch SD, SMD, reverse on-board, right-angle, push-pull (https://www.hirose.com/product/en/download_file/key_name/DM3AT-SF-PEJM5/category/Drawing%20(2D)/doc_file_id/44099/?file_category_id=6&item_id=06090031000&is_series= Micro SD, SMD, reverse on-board, right-angle, push-pull (https://media.digikey.com/PDF/Data%20Sheets/Hirose%20PDFs/DM3D-SF.pdf 1.10mm Pitch microSD Card Connector, Reverse Type, Outer Tail, Without Ejector (https://global.kyocera.com/prdct/electro/product/pdf/5638.pdf SD card connector, top mount, SMT (http://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Customer+Drawing%7F2041021%7FB%7Fpdf%7FEnglish%7FENG_CD_2041021_B_C_2041021_B.pdf%7F2041021-4 Micro SD, SMD, reverse on-board, right-angle, push-pull (https://media.digikey.com/PDF/Data%20Sheets/Hirose%20PDFs/DM3D-SF.pdf 1.10mm Pitch microSD Memory Card Connector, Normal Type, Outer Tail, Without Ejector (https://global.kyocera.com/prdct/electro/product/pdf/5638.pdf SD Card Connector, Normal Type, Outer Tail, Spring Eject Type (https://global.kyocera.com/prdct/electro/product/pdf/5638.pdf SD card connector, top mount, SMT (http://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Customer+Drawing%7F2041021%7FB%7Fpdf%7FEnglish%7FENG_CD_2041021_B_C_2041021_B.pdf%7F2041021-4 Micro SD, SMD, right-angle, push-pull (https://media.digikey.com/PDF/Data%20Sheets/Hirose%20PDFs/DM3D-SF.pdf 1.10mm Pitch microSD Memory Card Connector, Normal Type, Outer Tail, Without Ejector (https://global.kyocera.com/prdct/electro/product/pdf/5638.pdf SD card connector, top mount, SMT (http://www.te.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Customer+Drawing%7F2041021%7FB%7Fpdf%7FEnglish%7FENG_CD_2041021_B_C_2041021_B.pdf%7F2041021-4 Micro SD, SMD, top-mount, push-push (https://www.hirose.com/product/document?clcode=CL0609-0004-8-82&productname=DM1AA-SF-PEJ(82)&series=DM1&documenttype=2DDrawing&lang=en&documentid=0000915301 Hirose FH41, FFC/FPC connector, FH12-16S-0.5SH, 16 Pins (https://www.molex.com/pdm_docs/sd/026605050_sd.pdf), generated with kicad-footprint-generator Mounting Hardware, inside through hole M3.
