This repo contains the electronic design files of the new revision of DSL's RGBW LED driver board.
The original one was designed by lionello. Since I don't have Eagle, I'm redrawing the whole thing. I made the following enhancements:
- Added white LED channel
- Using ESP-WROOM-02 instead of ESP12. Both are ESP8266-based chip.
- Added bypass capacitors
- Added reverse polarity protection for voltage regulator input
- Using SMD components except for connectors
- Added mounting holes
- Replaced LDO with DC-DC buck converter
- Added power indicator
- Added programming header and removed unneeded programming button
- Added GPIO header for potential future expansion
- Replaced first-stage BJT with MOSFET
- Added gate resistor to MOSFET
- Added Dimsumlabs' logo and other info on silk mark
This new hardware design is backward-compatible with the original firmware.
