Overview
Active3-rpi hub75-adapter is an open-source printed circuit board by vitorleal, from the vitorleal/matrix-led-python repository on GitHub, published under the GPL-2.0 licence. It is a 2-layer board of 83.8 × 33.7 mm with 14 parts on 68 nets, routed with 719 tracks and 18 vias.
It is built around the 74HC245D. Its parts include 4 capacitors, 4 ICs and 3 connectors. It belongs with the interfaces and adapters boards of this library.
Main components
1README
adapter/active/README.mdAdapter PCB to support up to 2 panels
- Supports one panel for Raspberry PIs with 26 GPIO pins and two panels for newer plus models and Raspberry Pi 2 that have 40 GPIO pins.
- Uses HCT245 to level shift signals from 3.3V to 5V and shield the Raspberry Pi GPIOs from overloading.
- This supports two panels and provides convenient breakouts for I²C and the serial interface.
- Open source KiCAD PCB EDA format.
- If you are interested in connecting three RGB panels, check out the Active-3 board (it won't support the serial intefaces though).
For multiple parallel boards to work and using the I2C and serial interface you have to uncomment
#DEFINES+=-DSUPPORT_MULTI_PARALLEL # remove the '#' in the beggingin lib/Makefile.

Questions
How big is the Active3-rpi hub75-adapter PCB?
It measures 83.8 × 33.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Active3-rpi hub75-adapter use?
14 parts, built around the 74HC245D. 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 Active3-rpi hub75-adapter KiCad files?
From the vitorleal/matrix-led-python repository on GitHub, at the commit this page was made from: the board is adapter/active-3/active3-rpi-hub75-adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Active3-rpi hub75-adapter design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
