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) The attached file can be download from Download station |
| 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 powered on, the chip starts depending on the voltage level of the BOOT pin: · BOOT is 1 ：Start from flash · BOOT is 0 ：Download from uart |
