LILYGO T-A7068X: The Robust Wifi/ BLE Development Board

LILYGO has released its new ESP32-based, T-A7068X boards with a 4G LTE modem. It consists of two variants T-A7608E-H & T-A7608SA-H that feature SIMCOM A7608E-H and SIMCOM A7608SA-H. The SIMCOM A7608E-H supports the markets in the Middle East, Europe, Africa, South Korea, and Thailand whereas SIMCOM 7608SA-H serves regions such as Australia, New Zealand, and South America.

The SIMCOM A7608E-H and SIMCOM A7608SA-H offer download/upload speeds up to 150 Mbps and 50 Mbps. In comparison with its predecessors T-A7608SA and T-A7608E, the T-A7608SA-H and T-A7608E-H have enhanced from 10(DL)/5(UL) to 150(DL)/50(UL). As a result, the new T-A7608X  boards have ten times faster Download Link (DL) and Upload Link (UL).

The ESP32-WROVER-E module, based on an ESP32 dual-core processor operating at 240 MHz and includes 4MB Flash memory and 8MB PSRAM, drives these boards. For superior connectivity, it gets the support of WIFI 4 and Bluetooth 4.2/ 5.X technology along with the PCB antennas. The new T-A7068X boards support GPS since they are also providing a GPS antenna. It also consists of I/O expansions including two 16-pin headers which permit the expansion of these boards even with RS485 and CAN bus interfaces. These I/O expansions also support GPIOs, ADC, DAC, touch interface, UART, I2C, SPI, VN/VP, Reset, VBUS, VBAT, 3.3V and GND. The detailed pinout details for T-A7608E-H & T-A7608SA-H are given below.
