The PCB, with tolerances // wall_thickness = how deep to make fitting inside a case easier. Or 10mm if it can fit; losing the bodge area. Assembly Tests: Glide In - ~27K to U3-8? No, transistors maybe activate? - Clock rate (B100k) (not sure yet which 2 pins LED_Rectangular Rectangular Rectangular size 5.0x2.0mm^2 z-position of LED center 2.0mm, 2 pins, http://www.kingbright.com/attachments/file/psearch/000/00/00/L-2774GD(Ver.7B).pdf LED_Rectangular Rectangular Rectangular size 3.9x1.8mm^2 2 pins Ceramic Resomator/Filter Murata TPSKA, http://cdn-reichelt.de/documents/datenblatt/B400/SFECV-107.pdf, hand-soldering, 7.9x3.8mm^2 package SMD Crystal Oscillator Seiko Epson MC-306 https://support.epson.biz/td/api/doc_check.php?dl=brief_MC-306_en.pdf, 8.0x3.2mm^2 package SMD Crystal SERIES SMD2016/4 http://www.q-crystal.com/upload/5/2015552223166229.pdf, 2.0x1.6mm^2 package SMD Crystal SERIES SMD7050/4 https://www.foxonline.com/pdfs/FQ7050.pdf, 7.0x5.0mm^2 package SMD Crystal SERIES SMD0603/2 http://www.petermann-technik.de/fileadmin/petermann/pdf/SMD0603-2.pdf, hand-soldering, 6.0x3.5mm^2 package SMD Crystal TXC 9HT11 http://txccrystal.com/images/pdf/9ht11.pdf, hand-soldering, 2.0x1.2mm^2 package Ceramic Resomator/Filter Murata SFECV, http://cdn-reichelt.de/documents/datenblatt/B400/SFECV-107.pdf, 6.9x2.9mm^2 package SMD Crystal SERIES SMD2520/4 http://www.newxtal.com/UploadFiles/Images/2012-11-12-09-29-09-776.pdf, 2.5x2.0mm^2 package SMD Crystal 2012/2 http://txccrystal.com/images/pdf/9ht11.pdf, hand-soldering, 2.0x1.2mm^2 package SMD Crystal Seiko Epson MC-506 http://media.digikey.com/pdf/Data%20Sheets/Epson%20PDFs/MA-505,506.pdf, 11.7x4.0mm^2 package SMD Crystal Oscillator Seiko Epson MC-146 https://support.epson.biz/td/api/doc_check.php?dl=brief_MC-156_en.pdf, 6.7x1.5mm^2 package SMD Crystal SERIES SMD7050/4 https://www.foxonline.com/pdfs/FQ7050.pdf, hand-soldering, 7.0x5.0mm^2 package Miniature Crystal Clock Oscillator ECS 2520MV series, https://www.ecsxtal.com/store/pdf/ECS-2520MV.pdf Miniature Crystal Clock Oscillator TXC 7C series, http://www.txccorp.com/download/products/osc/7C_o.pdf, 5.0x3.2mm^2 package SMD Crystal ABS25 https://abracon.com/Resonators/abs25.pdf, 8.0x3.8mm^2 package SMD Crystal Seiko Epson SG-8002JC https://support.epson.biz/td/api/doc_check.php?mode=dl⟨=en&Parts=SG-8002DC, 10.5x5.0mm^2 package SMD Crystal MicroCrystal CC1V-T1A series https://www.microcrystal.com/fileadmin/Media/Products/32kHz/Datasheet/CC1V-T1A.pdf, hand-soldering, 8.0x3.7mm^2 package SMD Crystal EuroQuartz MJ series http://cdn-reichelt.de/documents/datenblatt/B400/MJ.pdf, hand-soldering, 5.0x3.2mm^2 package 14-lead dip package, row spacing 7.62 mm (300 mils), body size 9.78x25.04mm (see e.g. Http://www.ti.com/lit/ds/symlink/drv5023.pdf TO-92L leads in-line (large body variant of 8-Lead Plastic Dual Flat, No Lead Package (MF) - 3x3x0.9 mm Body [SOIC] (https://docs.broadcom.com/docs/AV02-0169EN SOIC 1.27 16 12 Wide 16-Lead Plastic HTSSOP (4.4x5x1.2mm); Thermal pad with vias; (http://www.ti.com/lit/ds/symlink/drv8800.pdf HTSSOP, 16 Pin.
