PCB for CREE JK3030 LEDs, for use with a WiLED lighting controller
LED JK3030 is an open-source printed circuit board by seanlano, from the seanlano/WiLED-JK3030 repository on GitHub. It is a 2-layer board of 24 × 40 mm with 11 parts on 7 nets, routed with 28 tracks and 0 vias.
It is built around the JK30-300. Its parts include 6 diodes and 2 connectors.
Circuit board for up to six CREE JK3030 LEDs. To be used with a WiLED main board, which provides a 350 mA constant-current DC supply to the LEDs. The PCB is intended to be aluminium rather than FR4, and attached to a heatsink.
All hardware schematics and design files are released under the CERN Open Hardware Licence v1.2. Please see LICENCE for details.
