Blip hackpad: common questions

What microcontroller does the Blip hackpad use?

The Blip hackpad is built around the 113991114, from the ESP32 family.

How big is the Blip hackpad PCB?

The Blip hackpad measures 115.3 × 130.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Blip hackpad?

31 components, from 8 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 Blip hackpad design files?

From the quantumcompiler32/Blip_hackpad 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 Blip hackpad design in my own project?

Yes, under the terms of its MIT license, which quantumcompiler32 chose for the repository.

Can I test firmware for the Blip hackpad 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.
