LILYGO® TTGO T-SIM7000G SIM Development Board ESP32 WiFi Bluetooth GPS Module SIM7000G SIM7000E SIM7000A SIM7000JC 4/16MB Flash

Version update includes:

Enhanced battery protection against reverse polarity, overcharging, and over-discharging.

Improved GPS power management to reduce power consumption, with a minimum sleep mode power of 300uA.

Notes for new Users:

SIM7000/SIM707G does not support a 4G network. Please ensure that the USIM card you use supports 2G(GSM)/NB-IOT access, SIM7070 positioning and cellular cannot be used simultaneously. Please disconnect the network when positioning, and turn off GPS when connecting to the network

When an SD card in you can not upload software in Arduino IDE since the SD card uses IO2 as CS, the SD card must be removed when uploading a new sketch.

On Version 20200415, When using GPS the SIM7000G(GPIO4)/SIM7070G(GPIO5)(Physical pin number 48) needs to be set to HIGH to enable the antenna modem.sendAT(“+CGPIO=0,48,1,1”); once finished the pin can be set LOW modem.sendAT(“+CGPIO=0,48,1,0”); to prevent power leaking to the GPS antenna, This will make help battery life. If using USB or battery life is not a concern, it can be left HIGH.

If you are unable to access the network, please try , which will test the network connection. There are also binary files in the firmware directory; you can use the Flash Download Tools to download.

How to change the connection method?

For example, the Arduino_TinyGSM/AllFunctions.ino , you only need to change modem.setNetworkMode(38); to the corresponding number, and your network access speed depends on the carrier of the SIM card you use. Before using it, you can communicate with the operator of your SIM card.

The effect is as follows:

11. The initial network registration may be slow. Please be patient. You can configure the locked band as shown in the following figure.
