PCB's
Breakout boards for the Seeed Studio XIAO nRF52840 (Xiao BLE) and up to two 74HC595 Shift Registers. Taking inspiration from the revxlp, using two pogopins to reach the backside pads of the Xiao BLE
XiaoBLE__2xSR_SMD used the surface mound 74HC595 Shift Registers
XioaBLE__2xSR_TH uses the throuh hole version of the 74HC595 Shift register, all other components are the same.
status: PCB's in production, untested.

Questions
How big is the XiaoBLE 2xSR SMD PCB?
It measures 56.4 × 31.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the XiaoBLE 2xSR SMD use?
14 parts, built around the 74HC595 and PCM12SMTR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the XiaoBLE 2xSR SMD KiCad files?
From the hagata/kikeys repository on GitHub, at the commit this page was made from: the board is XiaoBLE__2xSR_SMD/XiaoBLE__2xSR_SMD.kicad_pcb and its schematic XiaoBLE__2xSR_SMD/XiaoBLE__2xSR_SMD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the XiaoBLE 2xSR SMD design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
