Product Description

Module Introduction

• AS32-TTL-100 is an industrial grade 100mW high stability wireless data transmission module. The module uses SX1278 main chip, LORA spread spectrum transmission, TTL level output, compatible with 3.3V and 5V IO port voltage. And the module on the basis of the old version has been upgraded as follows: the use of efficient loop interleaving error correction coding algorithm, coding efficiency, correction ability of error. In the event of sudden interference, it can actively correct disturbed data packets. 64-bit maximum continuous error correction greatly improves the module’s anti-jamming and transmission distance, and in the absence of error correction algorithm, this package of error cannot be thrown; LORA spread spectrum gives the module a longer communication distance.
• The module has four working modes which can be switched freely in operation. In power saving mode, the current consumption is only a few tens of AU, ideal for very low power applications.
• The working frequency of AS32 is 410MHz~441MHz, a total of 32 information channels, the interval of each channel is 1M. Serial port baud rate, transmit frequency, transmit power, RF frequency and other parameters can be changed online.
