- Description
1. On-board mature and stable -12F WIFI module, large capacity 4M Byte Flash
Function:
1. L, N: AC90-250V power supply
Introduction to GPIO terminal:
| Number | Name | Function | Number | Name | Function |
| 1 | GND | Power ground | 13 | IO10 | GPIO10 |
| 2 | Relay | The relay drive port is driven by IO5 by default. If you want to use other I / O to drive the relay, you can remove R14, and then connect the I / 0 of the drive relay to this Relay pin | 14 | MISO | Slave output input |
