The load on this line consists of a microcontroller and an LCD display (1Ah 5V DC). What can I use instead of the relay?


Here is the schematic:

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
