Handheld Linux Terminal
This is a serial terminal with a built-in single board computer running a Linux distribution. A NanoPi Neo Air running DietPi is connected via UART to a Raspberry Pi Pico. The Pico is connected via SPI to an Adafruit RA8875 board driving an 800x480 TFT display. The remaining pins of the Pico are used to scan a 71 key matrix keyboard. A DS3231 RTC module is connected via i2c with the NanoPi. The device is powered by a 10000mAh LiPo battery providing up to 15 hours of up-time. It can be charged through a micro-USB connector. The terminal supports ASCII, Latin-1 supplement, box-drawing, block, braille and some geometric-shape characters, as well as 256 colors.
