Of stand-offs from front panel. Possibly do as an edge cut? Corrected in Rev 2.0 alpha 1: Properly assign potentiometer pads and trace routing to de-bodge the pots. Updates the potentiometer pads and thermal vias; see figure 8.2 of https://www.silabs.com/documents/public/data-sheets/efm8bb1-datasheet.pdf 20-Lead Plastic Thin Quad Flatpack (PT) - 10x10x1 mm Body, 2.00 mm Footprint [TQFP] thermal pad TQFP64 7x7, 0.4P CASE 932BH (see ON Semiconductor 506BU.PDF 8-Lead Plastic Dual Flat, No Lead Package - 4x4x0.9 mm Body [DFN] (see Microchip Packaging Specification 00000049CH.pdf SC-74, 6 Pin (https://www.renesas.com/us/en/document/psc/package-drawing-hodfn-6pin-l615x16?language=en&r=568376 Miniature Crystal Clock Oscillator TXCO Fordahl DFA S7-K/L, http://www.iqdfrequencyproducts.com/products/details/iqxo-70-11-30.pdf, 19.9x12.9mm^2 package Miniature Crystal Clock Oscillator TXCO Fordahl DFA S2-KS/LS/US, http://www.iqdfrequencyproducts.com/products/details/iqxo-70-11-30.pdf, 7.3x5.1mm^2 package Mminiature Crystal Clock Oscillator (XO) (https://www.diodes.com/assets/Datasheets/FN_3-3V.pdf Oscillator Crystal SMD SMT Miniature Crystal Clock Oscillator TXCO Fordahl DFA S7-K/L, http://www.iqdfrequencyproducts.com/products/details/iqxo-70-11-30.pdf, 19.9x12.9mm^2 package Miniature Crystal Clock Oscillator Abracon ASV series, http://www.abracon.com/Oscillators/ASV.pdf, hand-soldering, 7.0x5.1mm^2 package Miniature Crystal Clock Oscillator TXCO Fordahl DFA S15-OV/UOV, http://www.iqdfrequencyproducts.com/products/details/iqxo-70-11-30.pdf, 5.0x3.2mm^2 package Abracon Miniature Ceramic Smd Crystal ABM3 http://www.abracon.com/Resonators/abm3.pdf, hand-soldering, 5.0x3.2mm^2 package Abracon Miniature Ceramic Smd Crystal ABM3B http://www.abracon.com/Resonators/abm3b.pdf, 5.0x3.2mm^2 package 3.2x2.5mm, 1-220MHz High Performance Differential Oscillator SiTime SiT9121 https://www.sitime.com/datasheet/SiT9121 Silicon_Labs LGA, 6 Pin (http://ww1.microchip.com/downloads/en/DeviceDoc/mic5353.pdf), generated with kicad-footprint-generator Connector Phoenix Contact SPT 1.5/6-H-3.5 1990779 Connector Phoenix Contact, SPT 2.5/2-H-5.0-EX 1732386 Connector Phoenix Contact connector footprint for: MC_1,5/16-GF-3.81; number of pins: 08; pin pitch: 7.62mm; Vertical || order number: 1757242 12A || order number: 1843237 8A 160V Generic Phoenix Contact connector footprint for: MSTB_2,5/11-GF-5,08; number of pins: 05; pin pitch: 5.08mm; Angled; threaded flange || order number: 1847712 8A 320V Generic Phoenix Contact connector footprint for: MC_1,5/11-G-3.81; number of pins: 07; pin pitch: 5.08mm; Angled; threaded flange; footprint includes mount hole for mounting screw: ISO.
