The TMK-M series includes TMK01-M, TMK02-M, TMK04-M, and TMK05-M, a total of 4 models of 8-channel full-duplex digital voice wireless communication module development boards. Based on LoRa technology, it can achieve communication across the 150-960MHz full frequency band. It supports 8-channel full duplex,40channels,8transceivers can send voice on each channel at the same time, and the number of receivers is unlimited.It can reserve a call position for designated personnel to ensure that they can always enter. The module adopts digital broadband spread spectrum technology, has a longer communication distance, strong anti-interference ability, and performs digital encryption on language transmission, unlike traditional analog systems. The module development board supports low power standby mode and sleep mode. The standby mode has low power consumption of 5mA. The rubber stick antenna has a gain of 2.5dBi, a 5km intercom distance, and a 15km data transmission distance.
