View: Base PCB v0.5

It's been a little while; it's time for a new (yet also old) formal release! The biggest change since v0.4 is the use of SMD resistors to sense the PCB flex, rather than gluing on strain gauges. This was recently informally stress-tested with 2 days of hands-on demos at Open Sauce 2023, and the resistors held up well with no noticeable calibration issues or drift during that period. While long-term durability is still unknown, that real-world accelerated testing makes me feel confident enough to promote that change to a release for now, and recommend it as a much easier alternative to attaching strain gauges.

• Use 2512 SMD resistors in place of strain gauges (#104)
• LCSC part numbers and notes for M1.6/M2 hardware
• Add alternative MT6701 LCSC/JLC part number
• Adding second footprint for 3V3 voltage regulator (#98) and Add BOM entries and note for new LDO
• Migrate to KiCad 6 (#96)
