The E22 series is the first wireless module in China to adopt Semtech's SX1262 RF chip. This chip provides a variety of modulation methods, such as LoRaTM and traditional GFSK. Its special LoRaTM modulation method increases the communication distance. At the same time, SX1262 owns two distribution methods, low-dropout regulator (LDO) and high-efficiency step-down DC-DC converter, under the premise of the choice of DC-DC mode, the receiving current is extremely low to achieve Low power consumption.
Compared with SX127x series, SX1262 can achieve up to 62.5kbps air data rate in Lora mode. In GFSK mode, air data rate can support up to 300kbps; according to the application of choice of power management, in the DC/DC mode, when in the maximum power output of 22dBm The SX1262's power consumption is only 118mA, and the efficiency is improved significantly. The SX1262 RF receiver power consumption is 4.8mA, which is less than half of the SX127x series 10mA receiving current.
As hardware platform,, users need to carry out secondary development.
DIO0, DIO1, DIO2, DIO3, DIO4, DIO5 are general I/O,available for various functions. Please refer to SX1262 datasheet,
they can be floated when free.
RST,TXEN,RXEN must be connected,among which RST control chip reset,TXEN, RXEN are for controlling RF switch.
Make it ground well with large space for grounding and small power ripple.
Filter capacitor is necessary and make sure it is close to pin VCC and GND.
Air data rate for SPI shall not be too high,1Mbps is recommended.
In transmitting,set TXEN as high communication level,RXEN pin is low level;
In receiving,set RXEN as high communication level,TXEN is low level; Before powering off, set TXEN,RXEN as low level.
One can reinitialize register setting when IC is free for better stability.
