Review on π» 4 Pack Serial Wombat 4B - I2C Smart I/O Expander with A/D Converter: Drive Servos, Switches, Quadrature Encoders, and UART/I2C Bridge - I2C Compatible with Arduino by Lawrence Feldman
Solved my problems with Wemos with E-Paper display
I am building a project with Wemos and an E-Paper display. Not enough gpio after connecting the display (epapers spi interface used 6). I came across a wombat and it was just what I needed. E-Paper also takes a relatively long time to update, making it difficult to eliminate key bounce. Wombat solved this problem and I look forward to using its other features in future projects.
- Decent performance
- Minor problems
