About the BaBot Base THT PCB

BaBot Base THT is an open source AVR/Arduino PCB design by Hemlock-white, published on GitHub. It is a 2-layer board measuring 100 × 98.9 mm, with 17 components from 15 distinct parts.

Its main chip is the Arduino Micro A000053, from the AVR/Arduino family. Other key parts include the CD74HC4067E, MIKROE-2332 DIGI POT 2, 20-way header to Plate and Red LED 3mm. By type, the board carries 5 ICs, 4 resistors, 2 connectors, 2 capacitors and 1 switch.

From the project

initialTHTBase/ preserves the first Base conversion, before the multiplexer module and trimmer changes. The early state is also represented by the second commit in this repository.

initialTHTBase/ preserves the first Base conversion, before the multiplexer module and trimmer changes. The early state is also represented by the second commit in this repository.

base2layerdraft/ preserves the later two-layer Base attempt. It is not fabrication-ready: the last recorded DRC had six signal connections and one ground connection open. base2layertrials/ contains intermediate routing experiments. Open these only as historical design files, not as the current Base.

BaBot Base THT: common questions

What microcontroller does the BaBot Base THT use?

The BaBot Base THT is built around the Arduino Micro A000053, from the AVR/Arduino family.

How big is the BaBot Base THT PCB?

The BaBot Base THT measures 100 × 98.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BaBot Base THT?

17 components, from 15 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 BaBot Base THT design files?

From the Hemlock-white/Babot_revisioned_Mechatronics_TermProject 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 BaBot Base THT design in my own project?

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

Can I test firmware for the BaBot Base THT 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.
