Connecting #ST7789's Backlight Pin (BLK) to 3V3 saves us one precious #BL602 Pin ... But we won't be able to switch off the backlight and reduce Power Consumption

Hi @lupyuen, maybe use a ATMega with spi/I2C code to manage more pins ?
@memiks I think an I2C GPIO Extender might be good ... Since most of the pins I need are plain GPIOs: https://www.tindie.com/products/SwitchDocLabs/8-gpio-extender-board-i2c-controlled/
...And that was one of many Kitchen Sink Photos I've taken 😉
