Description:
This product can be placed in the form of two kinds of interfaces, such as chip
type and pin-in soldering type. So, the pin is shipped as standard 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, accurate 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 from 2.4GHz to
2.5GHz. The module has sufficient transmission 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
different circuits. In addition, the GT-24 module comes with a built-in PCB
antenna and an ipx external antenna, which greatly improves the module's charge
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 to the LNA enable pin. When CE = 1, the LNA is enabled. When CE = 0,
the LNA is disabled. This operation is fully compliant 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 at 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 listed in the
nRF24L01P technical manual, but we recommend changing to: SPI operation pre-high
CE, until the transmission interrupt is completed, then maintaining 1mS high
time and then lowering the CE. The purpose of this is to immediately switch to
receiving mode after the GT-24 has been sent. If CE = 0, the LNA is off,
detrimental to the reception sensitivity.
Note that the grounding is good, there is a large area of paving, the power
supply ripple is small, and the filter capacitor should be added and as close as
possible to the module VCC and GND pins.
