Okay, #TaviscoMacropad V4 is coming to life! Just bought the parts from AliExpress:
- A second screen (a black/white/red e-ink this time)
- A VML7700 lux sensor
- A APDS-9960 moviment sensor
- SGP41 and SCD41 air quality sensors
- INA226 current sensor
- An SD Card SPI interface
- Piezo buzzer
- And a MCP23017 GPIO expander as the Raspberry Pi Pico will ran out of usable GPIOs because of the key matrix :)
I'm excited!
