NRF24L01+ SI24R01 POWER ENHANCED VERSION 2.4G WIRELESS MODULE

SI24R1 and NRF24L01 are completely compatible (SPI register, definition timing, the state diagram), which can communicate with each other, support NRF24L01+ all communication functions

1/ 7dBm output power

SI24R1 default mode output power is 2~3dBm, if you want to output 7dBm, the register address 0x06 (RF_SETUP) the lowest register write 1 (NRF24L01+ without the use of the bit, the default is 0), namely 0x06 register a minimum of four to 1111

2/ SI24R1 emission problem

Launch operation mode of SI24R1 and NRF24L01+ exactly the same, cause problems: if the register is powerdown mode operation, higher CE to at least 2ms, because the powerdown model of crystal does not work, crystal is from close to emission data need about 2ms. If the standbyI mode to drop-down CE high, that is not problem, CE only needs a pulse of 10us, because under the mode of standbyI crystal is the work (current is very small, only dozen microamperes)
