Attention

Item Attention
Electrostatic protection Avoid static electricity hitting the PCBA. Release the static electricity of hand before touching the PCBA
Operating voltage The operating voltage of each GPIO has been marked in the schematic. Please do not allow the actual operating voltage of the GPIO to exceed the rated value, otherwise the PCBA will be permanently damaged
FPC Connector When connecting FPC cable,make sure that the row is completely inserted into the row without bias
Plug and Remove Power off completely before plugging or removing it
Avoid short circuit During the power-on, avoid any liquid or metal touching PCBA components,otherwise the PCBA will be damaged even burn
Suggestion for Design Before hadrware design, see this post https://bbs.sipeed.com/thread/1721 (Use Web Translation)
BANK VDDIO1:GPIO 0-8,1.8V/3.3V
VDDIO2:GPIO 11-15,GPIO 40-41, 3.3V only
VDDIO3:GPIO 16-23,1.8V/3.3V
VDDIO4:GPIO 24-39,1.8V/3.3V
BOOT Mode When power on, the chip starts depend on the the voltage level of the BOOT pin:
· BOOT is 1 :Start from flash
· BOOT is 0 :Download from uart
