It has a high sensitivity of -148dBm and a transceive rate of 300 kbps, ensuring reliable data transmission over extended distances. The module also includes a NEO-6M GPS module, offering accurate positioning and timekeeping. It features an onboard RTC crystal and supports interrupt and wake-up functions. A power management unit (PMU) AXP192 efficiently manages power consumption and supports multiple power supply options. The module can be powered through a USB Micro connection or an 18650 battery holder, with USB capable of charging the battery. For usability, the T-Beam V1.1 has three onboard buttons for power, IO38, and reset functions. It comes with a 3D Wi-Fi antenna by default and supports an external Wi-Fi IPEX antenna (requires a resistance jump). A LoRa antenna and a GPS ceramic antenna are included for improved signal reception.
