support for error recovery varies between each micro-controller type.
It is generally recommended to only use i2c devices that are on the
same printed circuit board as the micro-controller.</p>
<p>Most Klipper micro-controller implementations only support an
<code>i2c_speed</code> of 100000. The Klipper "linux" micro-controller supports a
400000 speed, but it must be
<a href="RPi_microcontroller.html#optional-enabling-i2c">set in the operating system</a>
and the <code>i2c_speed</code> parameter is otherwise ignored. The Klipper
"rp2040" micro-controller supports a rate of 400000 via the
<code>i2c_speed</code> parameter. All other Klipper micro-controllers use a
100000 rate and ignore the <code>i2c_speed</code> parameter.</p>
