Mobiflight gtx335-transponder: common questions

What microcontroller does the Mobiflight gtx335-transponder use?

The Mobiflight gtx335-transponder is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Mobiflight gtx335-transponder PCB?

The Mobiflight gtx335-transponder measures 154.8 × 38.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mobiflight gtx335-transponder?

47 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mobiflight gtx335-transponder design files?

From the JorgHendriks/mobiflight-gtx335-transponder repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mobiflight gtx335-transponder design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Mobiflight gtx335-transponder without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
