The TTGO LoRa32 V2.1 development board is a last-generation wireless module, designed for IoT applications, intelligent systems and long-distance communication solutions.
The board operates at 868MHz frequency, ensuring extended compatibility and excellent performance in any environment, with the possibility of long-distance radio communication up to 15Km in direct line of sight (open environment). The included SMA antenna improves signal transmission, and the extremely high reception sensitivity (-139dBm) guarantees reliable communication even in difficult conditions.
It has a transmission power of +20dBm and reception sensitivity of -139dBm with an acceptable consumption of 10~14mA in standby, being optimized for portable applications.
It has connectivity through the SPI Interface for quick and easy integration with various devices.
It is compatible with FSK, GFSK, MSK, GMSK, LoRa and OOK.
It works in the range of -40℃ to +85℃, for use in extreme environments, being also suitable for areas such as weather balloons.
It has the function of automatic frequency correction, digital RSSI, fast switching and frequency hopping.
The board comes with an integrated LCD display
