Daronjli dongle: common questions

What microcontroller does the Daronjli dongle use?

The Daronjli dongle is built around the ESP32-WROVER-E-N16R8, from the ESP32 family.

How big is the Daronjli dongle PCB?

The Daronjli dongle measures 45.2 × 29.7 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Daronjli dongle?

50 components, from 25 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 Daronjli dongle design files?

From the manhoosbilli1/daronjli-dongle 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 Daronjli dongle design in my own project?

The repository has no license, so all rights stay with manhoosbilli1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Daronjli 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.
