About the Ax chip PCB

Ax chip is an open source NXP PCB design by richardeoin, published on GitHub. It is a 2-layer board measuring 41 × 60.5 mm, with 76 components from 43 distinct parts.

Its main chip is the DS2401P, from the NXP family. Other key parts include the CHIPv1_0, TPS73433, AX5043, TG-5006CJ and MGA-62563. By type, the board carries 30 capacitors, 13 inductors, 12 resistors, 9 diodes, 6 ICs and 5 connectors.

It belongs with the rf & radio designs in this gallery.

From the project

This folder contains the schematic files for the ax-chip header board.

This folder contains the schematic files for the ax-chip header board.

The board uses a single AX5043 radio, with separate antenna ports for transmit and receive. The recieve port has an integrated Low Noise Amplifier (LNA). Not yet tested

The LNA used is an Avago MGA-62563, but a MGA-61563 or MGA-68563 could also be used, by adjusting the bias resistor R12. By default the MGA-62563 is biased to 3.3V, 30mA.

Ax chip: common questions

What microcontroller does the Ax chip use?

The Ax chip is built around the DS2401P, from the NXP family.

How big is the Ax chip PCB?

The Ax chip measures 41 × 60.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ax chip?

76 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ax chip design files?

From the richardeoin/ax repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Ax chip design in my own project?

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

Can I test firmware for the Ax chip without the hardware?

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