Pseudo walkie talkie: common questions
What microcontroller does the Pseudo walkie talkie use?
The Pseudo walkie talkie is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.
How big is the Pseudo walkie talkie PCB?
The Pseudo walkie talkie measures 70.8 × 35.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pseudo walkie talkie?
51 components, from 21 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pseudo walkie talkie design files?
From the ApophisXIV/PCB-Desing repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Pseudo walkie talkie design in my own project?
The repository has no license, so all rights stay with ApophisXIV. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Pseudo walkie talkie 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.
