Remote-Antenna-Switch: common questions

What microcontroller does the Remote-Antenna-Switch use?

The Remote-Antenna-Switch is built around the ATMEGA328P-AU-atmel, from the AVR/Arduino family.

How big is the Remote-Antenna-Switch PCB?

The Remote-Antenna-Switch measures 193.6 × 95 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Remote-Antenna-Switch?

82 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Remote-Antenna-Switch design files?

From the EI9SP/Remote-Antenna-Switch repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Remote-Antenna-Switch design in my own project?

The repository has no license, so all rights stay with EI9SP. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Remote-Antenna-Switch without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
