Support 51 STM8S STM32 and other microcontroller development boards. The GT-24 module is a 2.4GHz, 100mW, high speed (up to 2Mbps airspeed), high stability, industrial-grade wireless transceiver integrated data transmission module. The module comes with a high-performance PCB antenna, precise impedance matching, and the nRF24L01P RF chip, which has higher reliability, more power levels, and longer transmission distance and lower power than the nRF24L01. In addition, the RFX2401 power amplifier chip is built in, and the built-in LNA has a receiving sensitivity of 10dBm and operates in the ISM band of 2.4GHz to 2.5GHz. The module has sufficient transmitting power, good characteristics, small harmonics, small channel crosstalk, and ultra-small volume. A model of industrial standards. And it has a standard spacing of 2.54mm in-line interface and 1.27mm patch interface, which is convenient for users to use with circuits. In addition, the GT-24 module comes with a built-in PCB antenna and an ipx external antenna, which greatly enhances the module's free characteristics.
