Module introductions


AS62-T20 is a 100mW industrial-grade patch 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. The module adopts the efficient cyclic interleaving error correction coding algorithm, which has high coding efficiency and good error correction ability. In the case of sudden interference, the module can correct the interrupted data packets, and the maximum continuous error correction is 64bit, which greatly improves the module Anti-jamming ability and transmission distance, and in the absence of error correction algorithm, this error packet can only be discarded. Using LORA spread spectrum technology makes the module have a longer communication distance.
The module has four operating modes and can be switched freely at run time. In power saving mode, the current consumption is only a few dozen uA, ideal for ultra low power applications.
AS62 operating frequency is 410MHz ~ 441MHz, a total of 32 channels, each channel interval is 1M. Serial baud rate, sending and receiving frequency, transmitting power, RF rate and other parameters can be modified online .

TTL serial input, connected to external TXD output pin. Can be configured as open-drain or pull-up input, see parameter settings 




TTL serial output, connected to external RXD input pin. Can be configured as open-drain or pull-up output, see parameter settings 




Used to indicate the working status of the module, the user wake up the external MCU, power-on during the initialization period of self-test, it output low power level, can be configured to Open-drain output, or push-pull output, see parameter settings 




Power input, voltage 2.0-5.5V (Note: less than 3.6V the output power will decline, but the impact on the reception performance is very small.) 




Ground line, connected to the power supply reference ground
