About the SplitFlapDriverATtiny1616V4.kicad PCB

SplitFlapDriverATtiny1616V4.kicad is an open source AVR/Arduino PCB design by duonkha, published on GitHub. It is a 2-layer board measuring 30 × 60 mm, with 25 components from 17 distinct parts.

Its main chip is the ATTINY1616-MNR, from the AVR/Arduino family. Other key parts include the ULN2003ADR, SN65HVD72DR, C20617301 and C20617302. By type, the board carries 9 capacitors, 8 connectors, 5 ICs, 2 resistors and 1 diode.

From the project

A modular, 3D-printed split-flap display controllable over RS485 from a Raspberry Pi. Each module holds 64 characters and modules can be chained together to build a display of any width.
