Module GSM

SKU:M026

Description

This is a 2G and industrial wireless communication module, integrated an GSM/GPRS module M6315, released by China Mobile, supported GPRS class12 and GPRS CS-1, CS-2, CS-3, CS-4 encode, M6315 has LCC package type, features tiny dimension, highly reliability, strong anti-interference capability.
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 COM.GSM 2G Communication Module（SIM800C) which is fully compatible with this product.

Power Operation:

Power On: GPIO2 stay HIGH for 2s
Power Off: GPIO2 stay HIGH for 8s
Power On: Button long-press for 2s
Power Off: Button long-press for 8s
Reset module: GPIO26 HIGH

*The Global System for Mobile Communications (GSM) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets.*

M5Stack Fire has occupied GPIO16 / 17 to connect with the PSRAM by default, it's conflict with TXD / RXD (GPIO16, GPIO17) of GSM module. Therefore, when using the GSM module with the M5Stack Fire, you might have to cut the TXD and RXD from GSM module and wire fly to another set of UART pin

What is EasyLoader?

1.EasyLoader is a simple and fast program burner. Every product page in EasyLoader provides a product-related case program. It can be burned to the master through simple steps, and a series of function verification can be performed.

2.After downloading the software, double-click to run the application, connect the M5 device to the computer via the data cable, select the port parameters, and click "Burn" to start burning.

3.The CP210X (USB driver) needs to be installed before the EasyLoader is burned. Click here to download driver
