The TTGO T-SIM-7608E-H from LilyGO is a microcontroller based on an ESP32 with a built-in A7608E-H Module. This means that the module has numerous wireless communication options such as GNSS (GPS), Wi-Fi, Bluetooth and LTE. The board has a USB-C connection with which it can be programmed (USB-C cable not included). The module also has an integrated 18650 battery holder (battery not included).

Note: The schematic diagram in the link below states that there is an audio CODEC (NAU8810YG) on the module. However, this is not the case.
