Pin definition and Description:

Serial number Symbol Pin function
one GND Power ground
two VCC Power input DC 3.3V or 5V, specified when purchasing.
three EN High level or suspended = sleep mode; low level or ground = working mode.
four RXD Data input, connected to user's TXD
five TXD Data output, connected to user's RXD
six AUX Signal output, wake up user MCU
seven SET Set = high level or low level.
Note: en, TXD, RXD, aux, set are all 3.3V level, 5V MCU is recommended to do level conversion.
Working mode: sending or receiving data;
Two sleep modes (specified at the time of purchase, l version by default)
Yl-10t-l: RF chip and MCU master clock stop working, power consumption reaches the minimum (3ua);
Mcu-3300u, but the average power consumption of mcu-3300u is stopped.
Setting mode: it refers to the modification of working frequency, wireless transmission rate and serial transmission rate, verification mode, etc.
