Design files, firmware and linux scripts for my clever serial terminal, the Whitterm-220 - WT-220.
The WT-220 is a homage to the VT-220, providing a physical RS232 terminal with the full features of a Linux computer running on a Raspberry Pi.
KiCad design files for the rear io-panel:
USB-C input for USB-PD high current (3 A) supply to RPi. LEDs indicate detected current profile from UFP. I2C lines made available to SAMD for playing with USB-C device modes. MAX3232 RS232 transceiver provides RS232 level interface to RPi UART and SAMD UART. SAMD21 microcontroller provides boot button control…
