Publishing the USB-C breakout and 3.3 V regulator building block board as an open hardware KiCad project under the CERN-OHL-W-2.0 licence.

Sending the first RS485 breakout with 48 V passthrough building block board for manufacture, while refining the design around screw terminals, JLCPCB parts selection, and practical field use.

Load testing the USB-C and 3.3 V regulator building block board, including short-circuit behaviour, PPTC protection, and sustained 500 mA output testing.

The first assembled batch of my USB-C and 3.3V regulator building block board arrived from JLCPCB, ready for inspection, bring-up, and load testing.

Refining an RS485 breakout board with 48V passthrough by removing the RJ45 connector, switching to screw terminals, and separating the 48V and logic ground regions.

Designing an RS485 breakout board with screw terminals, optional RJ45 cabling, selectable termination and biasing, and 48V passthrough protection.

Designing a small USB-C breakout and 3.3V regulator building block board for future embedded and prototyping projects.

Creating reusable PCB modules for common circuit functions, with a focus on faster prototyping, safer regulator designs, and more production-ready hardware.

A first look at the Miniware TS21 USB-C soldering iron after a quick trial, covering heat-up time, portability, and early impressions for electronics prototyping.

Improving my embedded development workflow by creating modular, reusable PCB building blocks in KiCad, with an eye toward open hardware prototyping boards.
