About the Original PCB

Original is an open source STM32 PCB design by jgillick, published on GitHub under the MIT license. It is a 2-layer board measuring 102.1 × 16 mm, with 57 components from 28 distinct parts.

Its main chip is the STM32F411CE, from the STM32 family. Other key parts include the AP2210N-3.3TRG1, MCP73830, ESD7002WTT1G and GD25Q16CEIGR. By type, the board carries 16 capacitors, 13 resistors, 9 diodes, 6 connectors, 5 ICs and 4 transistors.

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

From the project

A self-contained microcontroller, battery, and power management system that fits in your pocket.

A kick-ass microcontroller board with everything you need in a tiny package that fits in your pocket. Integrated battery & power management system, fast ARM microcontroller, USB bootloader, 4 high-power PWM outputs, 12 GPIOs, satisfying pushbutton switch, and more.

After years of wiring together portable LED controllers that all consisted of a lithium battery, charge controller, shitty slide power switch, and an Arduino nano (or similar), I wanted something better. I always found those versions to be janky and fragile -- not to mention concerned that damaging the pouch cell battery might…

Original: common questions

What microcontroller does the Original use?

The Original is built around the STM32F411CE, from the STM32 family.

How big is the Original PCB?

The Original measures 102.1 × 16 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Original?

57 components, from 28 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 Original design files?

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

Can I use the Original design in my own project?

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

Can I test firmware for the Original without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
