Hub75 esp32s3 controller is an open source ESP32 PCB design by neusse: a 2-layer board with 25 components (25 distinct parts). It is built around the 3A USB eFuse / load switch, 3.3V regulator for ESP32, ESP32-S3-WROOM-N16R8 PSRAM, 74AHCT245 color/data level shifter and more.

Reviewed, versioned, first-class Codex integration for Konnect's KiCad MCP workflows

konnect-codex is a standalone Codex plugin for the Konnect server. It packages reviewed Codex-native skills, agents, hooks, and MCP configuration so Konnect behaves like a first-class Codex integration. It is deliberately separate from Konnect so each release can preserve a known-good Codex workflow without changing Konnect itself.

Release numbers identify the Konnect release reviewed by the plugin: konnect-codex v0.12.1 supports Konnect v0.12.1. A later -codex.N suffix identifies a companion-only revision for that unchanged upstream release. The exact reviewed upstream commit and guidance…
