* Note: Why there is only one switch on board, has one transistor missed? <br />
SMETECH factory recommended application circuit, RF switch selection is PE4259, we are using the model. SX1278 chip 20PIN control PE4259 4PIN, to achieve automatic switching transceiver. Mainly PE4259 function than ordinary RF switch powerful, the use of ordinary RF switch, you need to add a transistor in the circuit board in order to achieve automatic switching transceiver or CPU / SX1278 two GPIO to control the general RF switch tube Two I / O, to achieve transceiver switch (but not automatically switch). In order to reduce the on-board components, 16 * 16mm PCBA area reserved on the location of the shield, so choose this higher price of PE4259 RF switch design circuit. PE4259 than ordinary RF switch you about 3 to 5 times.<br />
