About the Thintyl main PCB

Thintyl main is an open source Nordic nRF PCB design by namachan10777, published on GitHub under the MIT license. It is a 2-layer board measuring 34.5 × 70.5 mm, with 58 components from 30 distinct parts.

Its main chip is the MDBT50Q-1MV2, from the Nordic nRF family. Other key parts include the MCP73871 and TPS63900. By type, the board carries 31 resistors, 7 connectors, 7 capacitors, 6 diodes, 3 ICs and 1 crystal.

From the project

The 3D model (model/) is written in OCaml using OSCADml.

A Nix flake provides a reproducible toolchain (OCaml + OSCADml + OpenSCAD). With direnv (and nix-direnv):

Without direnv you can use the flake directly:

Thintyl main: common questions

What microcontroller does the Thintyl main use?

The Thintyl main is built around the MDBT50Q-1MV2, from the Nordic nRF family.

How big is the Thintyl main PCB?

The Thintyl main measures 34.5 × 70.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Thintyl main?

58 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Thintyl main design files?

From the namachan10777/thintyl repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Thintyl main design in my own project?

Yes, under the terms of its MIT license, which namachan10777 chose for the repository.

Can I test firmware for the Thintyl main 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.
