E22-400TBH-02 LoRa module development test board
[Interface]：USB
[Size]：59.5*97mm
[Introduction]：E22-400TBH-02 is an entry-level development board that uses the E22-400T37S series LoRa module named for its high-power long-distance communication. This development board has a variety of transmission methods, works in the 230/433/470MHz frequency band, LoRa spread spectrum technology, TTL level output, and supports a power supply voltage of 4.5V~15V. Most of the pins of the module on the board have been led to pin headers on both sides. Developers can easily connect various peripheral devices through jumpers according to actual needs. The development board can also be plugged into a breadboard for use.
