The latest revision of the Moonlight Special driver. Original design by Mattaus, original firmware by JonnyC, modification and testing by RMM.
V3 Changes:
- Added OTC Capacitor Pad
- Cleaned Up and Deleted Outdated Pads
- Fixed Silkscreen Alignments
- Widened 7135 Pads for Easier Reflow & Chip Stacking
- Even Beefier Traces and More Vias! (More POWER!)
- Improved Edge Clearance
- Pin 3 to Ground Connection Now Does Not Require Bridging to Edge of Driver (Just Solder Over The Circle)
Components:
- MCU: attiny13a-SSU
- C1: 10uF 10V+ 0603 or 0805
- OTC: 1uF 0805
- 7135 Regulators
- R1: 19.1k 0603
- R2: 4.7k 0603
- D1: SOD-323 Schottky Diode
