High light
Highly extensible
Vision Master T190 has a rich set of pins and hardware resources, which will allow you to expand widely. The SH1.0-4P interface can be directly connected to the QuickLink series sensors.
Plastic support plate
A transparent plastic support platform is installed between the PCB and the display frequency, which can protect the electronic components on the board and enhance the heat dissipation function of the board.
FAQ
The default configuration of T190 board is PCB antenna, and the 2.4GHz antenna is a spring antenna. There is an additional interface on the board for 2.4GHz wireless signals. When connecting an external antenna, the resistor needs to be rotated 90 degrees to the left.

We strongly recommend using Arduino. We have complete technical support and provide complete LoRaWAN code for ESP32 Arduino framework.
You can find this type of socket by search “SH1.25 x 2”.
Please reinsert your USB cable, or try another cable.
If you use USB adapters, try to skip them and connect directly to the USB port on your PC.
Open your DEVICE MANAGER, select the port, and if prompted, try to install the CP210X driver
Try another computer or a different system
Open your DEVICE MANAGER, check to see if the device port can be found. If not, please refer to the previous topic “I can’t find serial port”.
Please check if your serial port is opened elsewhere.
Enter the BootLoader mode to upload, there are two ways to enter the mode:
connect the USB cable, hold down the User (or ORG or Boot) key, press RST once, and then release the User (or ORG or Boot) key.
Hold down the User (or ORG or Boot) key, then connect the USB cable.
This is a 10cm sensor adapter cable with specifications ranging from SH 1.0-4P to PH 2.0-4P. It is used to connect the development board and sensors. The sh 1.0-4P port is used to connect to the interface of the development board, while the ph 2.0-4P port is used to connect to the sensor interface. If you need this product separately, you can purchase it through this link.
Specification of board sensor connection port
Press and hold the Boot key, press RST once, and then release the Boot key. Alternatively, keep holding down the boot button and then connect the USB. Among them 21 button can be customized by user.
