Note: On a 5.7-inch LCD daughterboard, BL_CTRL(PA8) signal adjusts brightness of backlight by
mean of a pulse signal. Since BL_CTRL is shared with MII_MCO, which is in default setting,
SB57 must be removed and SB60 must be closed.
The orientation of the 5.7-inch LCD daughterboard can be changed by hinged standoffs and
pillars. Refer to
