It can apply to the communication requirement on diversity industrial, electricity, petroleum, transportation, financial, etc

In the GSM module scheme, we added more hardware resources, 1 reserved speaker- SPK1, 1 onboard speaker-SPK2, LEDs, 2 alternative antenna.
M6315 is 2.8V power input, so in the hardware of GSM module, we added a Bidirectional Voltage-Level Translator (TXS0104E), to switch the power supply to 2.8V.

This product is EOL now, we've released the updated version which is fully compatible with this product.
