Description
Specification: Model : GT-24Module size: 30.3 × 14.5mm (including PCB antenna)Operating frequency band: 2.4GHz ~ 2.525GHz (adjustable, 1MHz step)Interface mode: 1*8*1.27mm/2*4*2.54mm (The patch can also be used with the universal board and DuPont line)Supply voltage: DC 2.0-3.6V (Note: above 3.6V, the module will be permanently damaged)Communication level : 0.7VCC ~3.3V (VCC refers to the module supply voltage)Measured distance: 1000m (clear open space, maximum power, height 2m, 250k air speed)Transmit power: 4 levels adjustable (maximum 20dBm, approx. 100mW at maximum power)Air speed 250k ~ 2Mbps / 3 levels adjustable (250kbps, 1Mbps, 2Mbps)Shutdown current: approx. 30uA (test condition: CE=0, power-down mode, VDD=3.0V)Emission current: about 90mA (power supply capacity must be greater than 250m)Receive current: about 20mAAntenna form : PCB antenna / ipex carrier antennaCommunication interface : SPI maximum speed up to 10MbpsTransmit length: Single packet 1~32 bytes Level 3 FIFOReceive length : Single packet 1~32 bytes Level 3 FIFORSSI support : Not supported (only simple packet loss statistics are supported)Receive sensitivity: -94dBm@250kbpWorking temperature: -40 ~ +85 °C (industrial grade)Storage temperature: -40 ~ +125 °C (industrial grade) 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.Pin Instruction:
