README.mdNeewer LED panel modification
Homemade Arduino Nano based driver for the Neewer BP300 LED panel.
Features
- Single controller to sync two LED panels
- Color balance between cool and warm
- Brightness balance between two LED panels
- Total brightness adjustment
Implementation
- Basically PWM followed by a logic-level MOSFET, e.g. IRLZ44N
- Utilizing timers 1 and 2 of the ATmega328 chip to generate 2x2 PWM signals up to ~60kHz common frequency and individual duty cycles

Questions
How big is the Neewer PCB?
It measures 83.8 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Neewer use?
31 parts, built around the IRLZ44N. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Neewer KiCad files?
From the jurihock/NeewerLedMod repository on GitHub, at the commit this page was made from: the board is hardware/Neewer/Neewer.kicad_pcb and its schematic hardware/Neewer/Neewer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Neewer design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
