BackPCB should be 10 nF. Putting everything together is a consideration. FDM printing is the decade counter expects CLOCK to pass 1/2 of V+ (i.e. 6v) but many external clock sources cycle between 0v and 5v or even much less. - One idea: add a voltage to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a diameter between 16-19 mm: https://www.keyelco.com/product.cfm/product_id/826 Keystone #500, 12mm CR1220 battery holder, Memory Protection Devices P/N BA9VPC, http://www.memoryprotectiondevices.com/datasheets/BA9VPC-datasheet.pdf PP3 Battery Holder 18650 Battery Holder BH-331P Battery Type 3xAA battery CR1225 coin cell retainer Keystone type 107 battery holder Keystone type 105 battery holder Keystone type 1057 coin cell holder CR2032 retainer clip, SMT ( http://www.farnell.com/datasheets/1505853.pdf BC-2001 CR2032 2032 Battery Holder BH-331P Battery Type C Receptacle, GCT, 16P, top mounted, horizontal, 5A: https://gct.co/files/drawings/usb4105.pdf USB C Type-C USB3 receptacle SMD USB 2.0 and PD, 5A VBUS rating, https://datasheet.lcsc.com/lcsc/2211161000_HCTL-HC-TYPE-C-16P-01A_C2894897.pdf USB 3.0 type A Plug, Horizontal, http://katalog.we-online.de/em/datasheet/692112030100.pdf usb A plug horizontal Micro USB Type C, vertical, SMT, https://datasheet.lcsc.com/lcsc/2108072030_G-Switch-GT-USB-7051A_C2843970.pdf USB C Type-C Receptacle Hybrid USB TYPE C, VERT RCPT PCB, Hybrid, https://www.amphenolcanada.com/StockAvailabilityPrice.aspx?From=&PartNum=12401548E4%7e2A USB C Type-C USB3 receptacle SMD USB Power-only Charging-only 6P 6C USB4135-GF-A 16-pin USB-C receptacle, USB2.0 and PD, 5A VBUS rating, https://datasheet.lcsc.com/lcsc/2211161000_HCTL-HC-TYPE-C-16P-01A_C2894897.pdf USB 3.0 type A Plug, Horizontal, http://katalog.we-online.de/em/datasheet/692112030100.pdf usb A plug horizontal Micro USB Typ-B (http://www.molex.com/pdm_docs/sd/1051330031_sd.pdf Micro USB https://gct.co/files/drawings/usb3076.pdf Micro-USB SMD Typ-B Vertical Molex Vertical Micro USB B vertical female connector Universal Serial Bus (USB) Shielded I/O Plug, Type C, right-angle, SMT, https://datasheet.lcsc.com/lcsc/2204071530_G-Switch-GT-USB-7010ASV_C2988369.pdf USB Type A, Kycon KDMIX-SL1-NS-WS-B15, Vertical Right Angle, Surface Mount.
