| Size and weight | |
| Core board size | 25.4x45.0mm |
| Development board size | 47.0x47.0mm |
| Core board weight | 5.0±0.1g |
| Development board weight | 14.5±0.5g |
| Precautions | |
| start up |
Zeros requires the card to start (or solder SPI flash), only plug in the USB without any phenomenon |
| System debug serial port |
UART0, specific position reference pin diagram |
| USB interface |
OTG usb, power and communication |
| Bottom debugging |
It is recommended to use usb to serial port small board to connect "U0T R" and "G 5V" |
| Operating temperature | -20~85??/span> |
| Running current |
Running Linux no-load current is about 100mA, full load current is about 150~180mA, and LCD current is about 200~300mA. No card power-on current is about 50~60mA |
