Story

Specifications:

MCU: ESP-WROOM-32 based on Espressif ESP32 dual core Tensilica LX6 processor with 802.11 b/g/n WiFi and Bluetooth 4.2 LE.
SIM7600CE-M1S module: is a 2G/3G/4G communication and positioning module, supports LTE CAT4 download up to 150Mbs.
Support GPS, BeiDou, Glonass, LBS
Working voltage: 4.5-20VDC if using adapter or via USB cable.
USB-UART circuit using CP2102 driver with good performance
Standard size Arduino UNO
Using nano simcard slot (Push pull)
The standard 4V/2A power circuit also provides full power for the SIM module (if using a sim module, it should be powered from an external adapter to ensure stable operation).

ESP32 SIM COM 7600 V1.5

Communicate:

Control module SIM via UART 2 of ESP32 ( GPIO16, GPIO17 )
Network status LED
Led IO: IO2
Reset SIM module (IO18): high level
