Mimic: common questions

What microcontroller does the Mimic use?

The Mimic is built around the teensy_3.1, from the NXP family.

How big is the Mimic PCB?

The Mimic measures 82.6 × 27.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mimic?

60 components, from 17 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 Mimic design files?

From the psu-meteo/SuperDARN_Transmitter repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Mimic design in my own project?

Yes, under the terms of its MIT license, which psu-meteo chose for the repository.

Can I test firmware for the Mimic without the hardware?

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