Release notes - Marble v1.3

This release corresponds to the second production batch of Marble boards (v1.3) manufactured by Vector Fabrication Inc. in Milpitas, California. 38 boards were produced in this run in October 2022, procured by Berkeley Lab (28 units) and Osprey DCS (10 units).

Due to the worldwide IC component shortage, Berkeley Lab worked with Vector Fab during the assembly process to source alternative parts for certain components that were out of stock. The artifacts on this release include the fabrication package as sent to Vector Fab for production, along with the BOM file received from the vendor including the alternative parts finally loaded on the boards (marble-bom_with_non_stock_replacements_(marble-4dc985bd-fab).csv).

Errata / Rework

U52 should be changed from TCA9517BGKR to PCA9509DP (surface-mount rework).

The v1.3 BOM still did not include heat sinks, needed for U1, U2, and U35.
