Release notes - Marble v1.4

This release corresponds to the third pre-production batch of Marble boards (v1.4) manufactured by Vector Fabrication Inc. in Milpitas, California. Five (5) boards were produced in May 2023 for testing, in preparation for a larger production run. The major difference between the previous versions and v1.4 is the new power management chip from Analog Devices LTM4673.

This version included various additions/checks from the fab house:

  • Addition of serial number on the back silkscreen.
  • Heatsinks on U1 (FPGA) and U2 (clock mux).
  • Tested for no-short-circuited power-plane at the test points.

Following rework was done to get the boards to function:

  • Replaced U52 with PCA9509DP
  • Solder R309 with 4.7k
  • DNP R147 and populate R158
  • Swapped R39 and R40 from 2.2k to 4.99k
