GT-24:

Industrial grade GT-24 digital transmiion wirele 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 type and the pin-in soldering type. Therefore, the pin is sent by default and is not soldered. Support 51 STM8S 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 wirele transceiver integrated data transmiion module. The module comes with a high-performance PCB antenna, precise impedance matching, and the nRF24L01P RF , which has higher reliability, more power levels, and longer transmiion distance and lower power than the nRF24L01. In addition, the RFX2401 power amplifier 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 crotalk, 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 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 transmiion 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 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: operation pre-high CE, until the transmiion 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 poible to the module VCC and GND pins.

NRF24L01+ Wirele Module 2.4G This wirele Transceiver module is an easy and suitable module if you want to setup your wirele communication system with low cost!! This module can achieve a good balance between wirele transition performance and cost! You can easily add it with your own MCU/ARM/PIC/AVR/ system! 2Mbit/s, 1Mbit/s, 250Kbit/s, three selectable transmiion rate. MultiCeiver hardware and six receiver functions. 2 Mbit/s make high-quality VoIP is poible. +/- 60m crystal. Only require an external inductor in the antenna matching There is no need multi-layer PCB. 5V tolerance level inputs. Improved ShockBurst and the serial interface can be easy to connect with a variety of low-cost MCU. There si no need interface with the MCU. Received in the rate of 2Mbit/s, the peak current is 12.5mA. When the rate of 2Mbit/s @ 0dBm output,the peak current is 11mA. Power-down mode, power consumption is 400nA. Standby mode, power consumption is 32uA. 130us fast switching and wake time. With voltage regulator:Oltage regulators on board. Built-in 2.4GHz antenna,support up to six channels of data reception. Low operating voltage: 1.9-3.6V

NRF24L01 SMD The NRF24L01 is a monolithic transceiver that operates in the world's common ISM band of 2.4-2.5GHz. The wirele transceiver includes: Frequency Generator Enhanced SchockBurstTM Mode Controller Power Amplifier Crystal Amplifier Modulator Demodulator Output Power Channel Selection and Protocol The setting can be set to extremely low current consumption via the interface. When the transmit power is 6dBm in transmit mode, the current consumption is 9.0mA. The accept mode is 12.3mA and the current consumption mode is lower in standby mode. Ball open ISM band, the maximum 0dBm transmit power, free license to use. Support six channels of data reception 1. Low operating voltage: 1.9 ~ 3.6V low voltage operation 2. High rate: 2Mbps, because the air transmiion time is very short, greatly reducing the collision in the wirele transmiion (software set 1Mbps or 2Mbps air transfer rate) 3. Multi-frequency: 125 frequency points to meet the needs of multi-point communication and frequency hopping communication 4. Ultra-small: built-in 2.4GHz antenna, small size, 15x29mm (including the antenna) 5. Low power consumption: When working in answer mode communication, fast air transmiion and start time, greatly reducing the current consumption. 6.
