Size and Pin definition
Notes for usage
a. Pls use soft lead wire or other hard metal (like telescopic antenna), the length should be chosen according to the respective frequency (24cm for 315MHz, 18cm for 433.92MHz). The antenna should be stretched as straight as possible if it is using soft lead wire.
b. If put the module inside the metal case, the antenna should be fetched out of case. To connect the metal telescope antenna with 50ohm coaxial line will get better effect in transmission.
c. The power voltage needs to be stable with low ripple factor and multilevel wave filtering (such as adding magnetic ball, inductance, capacitance etc.)
