Product Detail

Product details

DL-1020 wireless transmitter is an ultra low-cost, highly flexible, high performance, OOK wireless transmitter module for 240 to 480Mhz wireless applications. With very low current consumption, the device modulates and transmits the data which is sent from the host MCU. An embedded EEPROM allows the frequency, output power and other features to be programmed into the chip.

H: remote keyless entry(RKE).

◆ Notes for usage

01
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, 17cm for 433.92MHz). The antenna should be stretched as straight as possible if it is using soft lead wire.
02
The power voltage needs to be stable with low ripple factor and multilevel wave filtering (such as adding magnetic ball, inductance, capacitance etc.)

03
If applying the module inside the metal housing, the antenna should be fetched out of housing. To connect the metal telescope aerial with 50ohm coaxial line will get better effect in transmission.
04
Since the wireless frequency is precious natural resources, please do not keep the module always at transmission condition
