About the Combined PCB

Combined is an open source AVR/Arduino PCB design by neatstranger, published on GitHub. It is a 4-layer board measuring 94 × 119.4 mm, with 19 components from 11 distinct parts.

Its main chip is the C2991932, from the AVR/Arduino family. Other key parts include the RA-08H(915), ATGM336H-5N31, X1B000301000200 and AP9101CK-AHTRG1. By type, the board carries 8 ICs, 6 capacitors, 2 transistors, 1 battery holder and 1 resistor.

It belongs with the rf & radio designs in this gallery, and the repository also holds 1 earlier revision of it.

Combined: common questions

What microcontroller does the Combined use?

The Combined is built around the C2991932, from the AVR/Arduino family.

How big is the Combined PCB?

The Combined measures 94 × 119.4 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Combined?

19 components, from 11 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 Combined design files?

From the neatstranger/pal-collar 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 Combined design in my own project?

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

Can I test firmware for the Combined without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
