Feature:1. Support 51 STM8S STM32 and other microcontroller development boards.2. The module is nRF24L01P + PA + LNA and its driving method is exactly the same as nRF24L01P. Users can operate according to the nRF24L01P chip manual.3. The CE pin is connected to the LNA enable pin. When CE = 1, the LNA is turned on. When CE = 0, the LNA is turned off. This operation is identical to the transmit and receive modes of the nRF24L01. In other words, the user does not need to care about the operation of the LNA at all.4. The CE can be connected high for a long time, but the module must first be set to the POWER DOWN power-down mode when writing to the register. It is recommended to connect the CE to the IO port of the MCU. The IRQ can be disconnected and the interrupt status can be obtained using the SPI polling mode. However, it is recommended to use an external interrupt from the microcontroller.5. The module's CE pin timing operation can reach the 10us mentioned in the nRF24L01P technical manual, but we recommend changing it to: SPI operation until CE goes high until the transmit interrupt is completed, then keep 1ms high time, then Lower the CE. The purpose is to switch to receive mode immediately after sending the GT-24. If CE = 0, the LNA is turned off, which will adversely affect the receiving sensitivity.Specification:Item Type:Wireless ModuleType:Direct Insert/Patch Mounting(Optional)Serial numberproduct nameparameterSummary1modelGT-24————2RF solutionnRF24L01P————3Module size30.3 x 14.5mm / 1.19 x 0.57in PCB antenna included4Working frequency2.4GHz-2.525GHzAdjustable, 1MHz step5Production ProcessLead-free environmentally friendly processMachine stickers, products must be machine-mounted to ensure consistent batch reliability6Interface mode1*8*1.27mm/2*4*2.54mmThe patch can also be used with the universal board and line.7Supply voltageDC: 2.0-3.6VNote: Voltages above 3.6V will cause permanent damage to the module.8Communication level0.7VCC-3.3VVCC refers to the module supply voltage9Measured distance1000mClear and empty, maximum power, height 2m, 250K air speed10Transmit power4 levels adjustable up to 20dBmAbout 100mW at maximum power11Air speed250K-2MbpsLevel 3 adjustable (250Kbps, 1Mbps, 2Mbps)12Shutdown currentAbout 30uATest conditions: CE=0, power down mode, VCC=3.0V13Emission currentAbout 90mAPower supply capacity must be greater than 250mA14Receiving currentAbout 20mACE=115Antenna formPCB antenna / ipex carrier antenna————16Communication InterfaceSPIHigh speed power up to 10Mbps17Launch lengthSingle packet 1-32 bytes3-level FIFO18Receiving lengthSingle packet 1-32 bytes3-level FIFO19RSSI supportnot supportOnly simple packet loss statistics are supported20Receiving sensitivity-B2294dBm@250Kbp————21Operating temperature-40~+85°CIndustrial grade22Working humidity10%-90%Relative humidity, no condensation23Storage temperature-40~+125°C---.Package List:1 x Module1 x Pin HeaderNote:Notice the grounding is good, the paving area is large, and the power supply ripple is small. The filter capacitor should be added as close as possible to the VCC and GND pins of the module.
