Teensy sdr: common questions
What microcontroller does the Teensy sdr use?
The Teensy sdr is built around the Teensy4.0, from the NXP family.
How big is the Teensy sdr PCB?
The Teensy sdr measures 102 × 76.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Teensy sdr?
61 components, from 36 distinct parts. The full bill of materials is listed on this page.
Where can I download the Teensy sdr design files?
From the electron271/teensy-sdr repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Teensy sdr design in my own project?
The repository has no license, so all rights stay with electron271. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Teensy sdr 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.
