MeshtasticStick: common questions
What microcontroller does the MeshtasticStick use?
The MeshtasticStick is built around the MDBT50Q-P1MV2, from the Nordic nRF family.
How big is the MeshtasticStick PCB?
The MeshtasticStick measures 31.1 × 94.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MeshtasticStick?
79 components, from 49 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 MeshtasticStick design files?
From the Oliver0804/MeshtasticStick repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the MeshtasticStick design in my own project?
The repository has no license, so all rights stay with Oliver0804. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MeshtasticStick without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
