QLAMP-main: common questions

What microcontroller does the QLAMP-main use?

The QLAMP-main is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the QLAMP-main PCB?

The QLAMP-main measures 142 × 58 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the QLAMP-main?

143 components, from 62 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 QLAMP-main design files?

From the hisashin/qNinjaLite 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 QLAMP-main design in my own project?

Yes, under the terms of its GPL-3.0 license, which hisashin chose for the repository.

Can I test firmware for the QLAMP-main 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.
