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 (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. In addition, the RFX2401 power amplifier chip is built in, and the built-in LNA has a receiving sensitivity of 10dBm and operates in the ISM band of 2.4GHz to 2.5GHz. The module has sufficient transmitting power, good spectral characteristics, small harmonics, small channel crosstalk, and ultra-small volume.
A model of industrial standards. And 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. In addition, the GT-24 module comes with a built-in PCB antenna and an ipx external antenna, which greatly enhances the module’s free characteristics.

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.
