THIS WEEK’S DISCOUNTED ITEM RF Transceiver Module 433MHz - Provides 1 way data transmission, meaning the transmitter can only transmit information and the receiver can only receive it. - The module itself cannot work on its own as it required some kind of encoding before being transmitter and decoding after being received. so it has to be used with an encoder or decoder IC or with any microcontroller on both ends. - The module uses ASK (Amplitude shift keying) and hence it’s easy to interface with microcontrollers. ⏳Discount period March 31 upto April 6 , 2025 (1 Week) Telegram Instagram YouTube TikTok Websites Facebook Original price 750 birr Discounted price 570 birr https://vector4engineering.com/product/rf-transceiver-module-433mhz/ 📍- Megenagna, Zefmesh Grandmall 3rd floor 301 📍- Mexico(sengatera), Yobek Building 7th floor 709A 📍- Mekelle around Romanat to CBE Road, @ Humera Hotel Ground floor 0993802995 Vector Megenagna 0970222227 Vector Mexico 0953888899 Vector Mekelle Branch
