Reopening #1251 — the CI on that PR wouldn't make forward progress, so
opening a fresh one as requested. @cnlohr

Requesting PID 1209:A69A for the Lagrange USB-UART Bridge.

Project: https://github.com/UNCOMMONGROUP/Lagrange

An open-source USB CDC-ACM to UART bridge built on the Renesas RA2L2
(Arm Cortex-M23) MCU, supporting baud rates up to 1.5 Mbps. Rather than a
fixed-function bridge IC, the conversion runs entirely in firmware, so the
same hardware can be retargeted to other interfaces in future releases.

Licensing:

  • Firmware: MIT — LICENSE
  • Hardware: CERN-OHL-S v2 — LICENSE-hardware

The repository contains the complete e2 studio firmware project, schematic,
PCB design files, production data (Gerber/BOM/PnP), and the enclosure model.

Design in altium, everything else checks out. This is a rehash of a github-CI-broken PR earlier. Created new PR to get CI to run properly.
