module can be greatly affected. According to the intensity of the interference, it is recommended to stay away from
the module.
Assuming that there are large electromagnetic interference lines around the module (high frequency digital, high
frequency analog, power supply) can also greatly affect the module's performance.
Keep away from the 2.4 GHz TTL protocol in some physical layers, e.g. USB 3.0;
The module must not be mounted inside the metal housing, which will greatly weaken the transmission distance.
3.2 Basic Circuit
1.As shown in the picture,the module can only connect the VCC,GND,TX and RX to perform the communication test.
2.PWM1, PWM2, PWM3 corresponding to SIGMESH HSL model;
3.DIO1 (PA0 boot corresponding to TLSR8253) and DIO2 (PA1 boot corresponding to TLSR8253) are switch volume
input guides that customers can access to and use according to their own needs.
4.The low power module can wake up via DI01, DIO2 and serial port after going to sleep.
