About the Apollo3 module

Apollo3 module is an open source Ambiq Apollo PCB design by TUDSSL, published on GitHub under the MIT license. It is a 4-layer board measuring 36 × 48 mm, with 44 components from 27 distinct parts.

Its main chip is the APOLLO3, from the Ambiq Apollo family. Other key parts include the MB85RS4MT. By type, the board carries 19 capacitors, 8 resistors, 6 connectors, 4 inductors, 2 ICs and 2 crystals.

It belongs with the retro computing and power & battery designs in this gallery.

Source code repository for ENGAGE: Battery-Free Game Boy

This is the official public repository for ENGAGE: the battery-free gaming console.

Battery-free devices can make phone calls, facilitate machine learning, or even track eyes, but immersive interactive experience without batteries has not been explored so far. In this project we focus on this ignored part of the battery-free device ecosystem. We explore how reactive and user-centric applications, mobile gaming in particular, can also be battery-free.

Apollo3 module: common questions

What microcontroller does the Apollo3 module use?

The Apollo3 module is built around the APOLLO3, from the Ambiq Apollo family.

How big is the Apollo3 module?

The Apollo3 module measures 36 × 48 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Apollo3 module?

44 components, from 27 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 Apollo3 module design files?

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

Can I use the Apollo3 module design in my own project?

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

Can I test firmware for the Apollo3 module without the hardware?

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