AstraControl

ESP32-based control PCB uses WiFi with an external antenna and 5Mbps RS-485 for communication, supporting various sensors and HMI devices for high-power LED fixtures or strips. Device can be configured to be a master or slave. The board connects to AstraDriver a high power LED driver board that uses 4x LED2001 drivers. Direct copper heat-sink PCB for LED diode AstraBeamLED. Power Distribution board AstraControlPower.

Interactive BOM

Check component locations by hovering over a specific component. The visual elements might not be precise enough for pcb review but can be very useful since it’s possible to pan and zoom. Not all BOM columns are available here, for datasheet links see BOM below.

KiCad Revision Inspector (KiRI)

KiCad Revision Inspector (KiRI) is a tool for comparing different versions of KiCad projects. It exports project revisions to SVG format for visual comparison using an onion skin view. This helps identify changes and errors in PCB designs. KiRI also includes a command line interface for generating viewable artifacts in any web browser.

View the PCB / Schematic in an interactive way, pan and zoom to see the details.
