Wyt dongle: common questions
What microcontroller does the Wyt dongle use?
The Wyt dongle is built around the ESP32-S2-MINI-2, from the ESP32 family.
How big is the Wyt dongle PCB?
The Wyt dongle measures 23 × 34 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Wyt dongle?
25 components, from 15 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 Wyt dongle design files?
From the mikesmitty/electronics-projects 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 Wyt dongle design in my own project?
The repository has no license, so all rights stay with mikesmitty. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Wyt dongle without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
