Designing a wireless call button -

Button Gets Pressed → MCU wakes from sleep → nRF24 transmits → receiver beeps.

TX design (this review):

- ATmega328P-PU in DIP socket, internal 8 MHz RC (no crystal)

- nRF24L01+PA+LNA via SPI, socketed via 2×4 header

- CR2032 battery, no regulator (both chips run at 3V)

- MSK-12C02 SMD slide switch for storage power cutoff

- Panel-mount momentary button wired to 2-pin header

- ICSP header for programming via Arduino-as-ISP

also, is it better to move the battery holder on back of the PCB?

Looking for feedback, thanks!

I was designing a pcb and was wondering if there is a better way to do this routing or this is just fine?
