Magic wifi: common questions

What microcontroller does the Magic wifi use?

The Magic wifi is built around the MSP430FR2355TDBTRDBT0038A_M, from the TI MSP430/CC family.

How big is the Magic wifi PCB?

The Magic wifi measures 99.1 × 85.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Magic wifi?

63 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the Magic wifi design files?

From the bluebandit21/magic-wifi repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Magic wifi design in my own project?

Yes, under the terms of its GPL-3.0 license, which bluebandit21 chose for the repository.

Can I test firmware for the Magic wifi without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug TI MSP430/CC firmware against it before you order a PCB.
