GT-24:

Industrial grade GT-24 digital transmission wireless module 2.4G NRF24L01+PA+LNA 1100 meters long distance

This product can be placed in the form of two types of interfaces, such as the chip type and the pin-in soldering type. Therefore, the pin is sent by default and is not soldered.
Support 51 STM8S STM32 arduino and other microcontroller development boards

The GT-24 module is a 2.4GHz, 100mW, high-speed (with an maximum over-the-air data rate of up to 2Mbps), highly stable, industrial-grade wireless transceiver module. It features a high-performance PCB antenna with precise impedance matching and employs the nRF24L01P RF chip, which offers higher reliability, more power levels, longer transmission range, and lower power consumption compared to the nRF24L01. Additionally, it integrates the RFX2401 power amplifier chip and a built-in LNA, improving receiving sensitivity by 10dBm. Operating in the 2.4GHz–2.5GHz ISM band, this module delivers sufficient transmission power, excellent spectral characteristics, low harmonics, and minimal channel interference. With an ultra-compact size and fully Murata-original components, it sets an industrial-grade standard. It also provides both standard 2.54mm pitch pin headers and 1.27mm SMT interfaces, allowing users to easily integrate it into various circuit designs. Furthermore, the GT-24 module includes both a built-in PCB antenna and an IPX connector for an external antenna, greatly enhancing its flexibility and offering users the utmost freedom in application.

Introduction to driving methods:

This module is nRF24L01P+PA+LNA, and its driving method is completely equivalent to nRF24L01P. Users can operate according to the nRF24L01P chip manual.
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 completely consistent with the transmission and reception mode of the nRF24L01. In other words, users don't have to care about LNA operations at all.
CE can be connected to a high level for a long time, but the module must first be set to POWER DOWN power-down mode when writing the register. It is recommended to connect CE to the IO port of the MCU.
The IRQ can be disconnected, and the SPI query mode can be used to obtain the interrupt status. However, it is recommended to use an external interrupt from the microcontroller.
The module's CE pin timing operation can be as high as 10us mentioned in the nRF24L01P technical manual, but we recommend changing to: SPI operation pre-high CE, until the transmission interrupt is completed, then maintain 1mS high time Then lower the CE. The purpose of this is to immediately switch to the receiving mode after the GT-24 is sent. If CE=0, the LNA is turned off, which will be detrimental to the receiving sensitivity.
Note that the grounding is good, there is a large area of paving, the power supply ripple is small, the filter capacitor should be added and as close as possible to the module VCC and GND pins.
