Functional Features
- Onboard the new series of Ai-WB2-12F modules, with a large capacity of 4M Byte Flash;
- All I/O ports and UART program download ports of the WB2-12F module are exported for easy secondary development;
- Onboard AC-DC power module, supporting AC90-250V power supply mode, onboard DC-DC power module, supporting DC7-28V power supply mode.
- Onboard EN enable buttons and programmable LED indicator lights;
- WB2-12F supports the use of BLDevCube burning tool and provides factory firmware;
- Onboard single channel 5V relay, output switch signal, suitable for controlling loads with operating voltage below AC 250V/DC30V;
Module testing
1. Power on the module and prepare a USB to TTL serial port module to plug into the computer USB.
The connection method between the serial port module and the development board is as follows:
| TTL serial port module | WB2-12F development board |
| GND | GND |
| TX | RX |
| RX | TX |
2. Open the SSCOM serial port data debugger, select the correct port and baud rate, click "Open Serial Port", and prepare to send AT commands
3. Send "AT" and return an "OK"; Then send 'AT+SYSIOMAP?' to query the IO pin mapping relationship table of the development board:
The order of all pins is sorted counterclockwise from the top left corner of the module, with pin numbers starting from 1 and corresponding chip pin numbers 1-22.
If the module does not have a corresponding chip pin, it is set to NC, as shown in the following figure:
4. The relay is controlled by the IO5 pin to control the switch state. Here, setting the IO5 pin (i.e. pin 19) to a high level will activate the relay and send "AT+SYSGPOWRITE=19,1".
The relay and relay indicator light will turn on; Send 'AT+SYSGPOWRITE=19.0', and the relay and relay indicator light will turn off:
The above module testing process is normal
