TLX9E5 868MHz

Multi-channel FM transceiver 868MHz with 8051 microcontroller

The TLX9E5 module is a low-power transceiver for the 868MHz band. The module contains a richly equipped 8051 microcontroller (including 4-channel 10-bit ADC, PWM, UART, WDT), the capabilities of which are entirely available to the user. The radio part itself performs all functions related to data transmission (checksums, run-up signals, addressing the sender and recipient addresses).
