About the Gb walkie talkie PCB

Gb walkie talkie is an open source Microchip SAM PCB design by idlehandsdev, published on GitHub. It is a 2-layer board measuring 65 × 67.5 mm, with 66 components from 33 distinct parts.

Its main chip is the SAMD21_MOD, from the Microchip SAM family. Other key parts include the CODECODER-VS1053B(LQFP48), PAM8302AAD, FGPMM0PA6H and AP2127K-1.8. By type, the board carries 20 capacitors, 20 resistors, 5 ICs, 5 switches, 5 inductors and 3 connectors.

It belongs with the robotics & motion designs in this gallery.

From the project

An open source "Fake" walkie-talkie for the Fake Ghost Tours for my friends in Vancouver.

The KiCad project lives in the idlehandsdev/gb_walkie_talkie repository on GitHub; these links point at the commit this page was built from.

Gb walkie talkie: common questions

What microcontroller does the Gb walkie talkie use?

The Gb walkie talkie is built around the SAMD21_MOD, from the Microchip SAM family.

How big is the Gb walkie talkie PCB?

The Gb walkie talkie measures 65 × 67.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gb walkie talkie?

66 components, from 33 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Gb walkie talkie design files?

From the idlehandsdev/gb_walkie_talkie repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Gb walkie talkie design in my own project?

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

Can I test firmware for the Gb walkie talkie without the hardware?

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