## Known Issues / Problems
### 64 character input limit on EDBG UART
When using STDIO directly through the debugger UART, no more than 64 bytes can
be read at once. This does limit the length of shell command lines to 63 bytes
(since a newline is needed) when using a terminal that only transmits whole lines.
(e.g. pyterm).
### I2C
When connecting an I2C device and a logic analyzer to an I2C port at the same
time, the internal pull-up resistors are not sufficient for stable bus
