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.

- Programmed the driver board with correct SSID and password so that it can be integrated with the lighting-related feature in DSL
- Obtained MAC and IP address of the driver boards so that the helios DNS can be fixed. The fix is to be performed by trouble
- Performed material recon for the installation of the backside
Thanks Nigel for wiring up the frontside driver board to the switch board. Also thanks Nigel for offering to help installing the LED strips to the backside.

- trouble had updated the DNS record. Now that the driver boards' web interface can be accessed via a domain name
TODO:
- Install another set of new LEDs on backside
- lionello - For making the original design and the firmware
- Sadale - For revising the hardware
- nigel - for reviewing the hardware design
- trouble - for proposing starting this project and reviewing the hardware design
- Other DSL members - for getting the whole thing installed to DSL, maintaining the firmware, etc.
