Ciro Santilli's hardware Raspberry Pi 2 Updated 2025-07-16
As of 2018-12, I believe that I might have fried the UART on this board when I burnt my last UART to USB converter by connecting ground to 5V.
Linux kernel logs don't show, but do show with the exact same components on the Pi 3 (SD card with
enable_uart=1 + image Raspbian Lite 2018-11-03 and UART cables).Serial from

Linux on SSH and bare metal blinker both work on this board, so the rest of the board seems alive.
