Features:
- 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.
- Also built-in RFX2401 power amplifier chip, built-in LNA, receiving sensitivity increased by 10dBm, working in the ISM band of 2.4GHz~2.5GHz.
- The module has sufficient transmit power, good spectral characteristics, small harmonics, small channel crosstalk, and ultra-small size. It is a model of all Murata raw materials and industrial grade standards.
- It has a standard spacing of 2.54mm in-line interface and 1.27mm patch interface, which is convenient for users to use with various circuits.
- The GT--24 module also comes with a built-in PCB antenna and an ipx carrier external antenna, which greatly enhances the module's free characteristics and gives the user the greatest freedom.
