About the Krt failed PCB

Krt failed is an open source Nordic nRF PCB design by Avinash1286, published on GitHub under the MIT license. It is a 4-layer board measuring 24 × 34 mm, with 59 components from 33 distinct parts.

Its main chip is the MDBT50Q-1MV2, from the Nordic nRF family. Other key parts include the W25N01GVZEIG, BQ25185DLHR, TLV75530PDBVR, MAX17048G+T10 and DRV2605LDGSR. By type, the board carries 21 resistors, 18 capacitors, 8 ICs, 4 connectors, 3 switches and 2 microphones.

It belongs with the wearables designs in this gallery.

These files are retained to make the engineering history reproducible. None is a manufacturing release or a valid final A03 routed board.

- krt-failed and the routing-attempt Circuit JSON contain a failed KRT run: zero copper and 199 disconnected-port findings. They must not be treated as a routed PCB. - pre-a03/aura-a02-route.ses contains 372 wire paths and 82 vias, with 24 connections remaining in that router run. It predates the corrected 8 × 6 mm NAND footprint and the A03 board/thermal design. It is not compatible with the current board. - pre-a03/aura-a02-routing-draft.kicadpcb was a…

Krt failed: common questions

What microcontroller does the Krt failed use?

The Krt failed is built around the MDBT50Q-1MV2, from the Nordic nRF family.

How big is the Krt failed PCB?

The Krt failed measures 24 × 34 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Krt failed?

59 components, from 33 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 Krt failed design files?

From the Avinash1286/pendent repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Krt failed design in my own project?

Yes, under the terms of its MIT license, which Avinash1286 chose for the repository.

Can I test firmware for the Krt failed 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.
