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 levels, and transmission distance and lower than the nRF24L01. In addition, the RFX2401 amplifier chip is in, and the -in LNA has a receiving sensitivity of 10dBm and operates in the band of 2.4GHz to 2.5GHz. The module has sufficient transmitting , good spectral characteristics, small harmonics, small channel crosstalk, and ultra-small volume. A of industrial standards. And it has a standard spacing of 2.54mm in-line interface and 1.27mm interface, which is convenient for users to with various circuits. In addition, the GT-24 module comes with a -in PCB antenna and an ipx external antenna, which greatly enhances the module's free characteristics.
