AS32-TTL-100 is a 100 mW industrial-grade wireless data transmission module with high stability working on 433MHz frequency.
The module uses SX1278 main chip, LoRa spread spectrum transmission, TTL level output, compatible with 3.3V and 5V IO port voltage.
LORA spread sptrum makes the module have a longer communication distance.
AS32 operating frequency is 410MHz to 441MHz with a total of 32 channels.
