This is a TTGO T-Motion V1.0 Smart Development Board S76G LORA STM32 GNSS Wireless Module 915Mhz USB Development Board.
The STM32 board has all the functions required for IOT. But these newly introduced TTGO boards are different from the previous. These are embedded with the STM32 chip with SX1276 which allows it to work with LoRa technology via SMA connected antenna. You can program this board using the Arduino environment. For code please refer to the link below.
