README
TestSequencer/README.mdTest Sequencer
This project surrounds an 8‑bit PIC microcontroller (PIC16F15324) with
- Power supply from a DC barrel jack with both ESD and reverse polarity protection. A 5V linear regulator runs the MCU and output buffers.
- A 32MHz external oscillator
- A 6p6c modular jack with ESD protection for ICSP programming with an ICD3 or ICD4
- 7 32mA capable logic‑level output buffers broken out to terminal blocks with ESD protection
- An input for a toggle switch or pushbutton broken out to a terminal block with ESD protection
- A slightly hacky but functional enclosure
After many times wanting to write some very basic assembly code to debounce a button and generate some simple logic‑level waveforms to control other equipment or directly interface with a circuit under test, I decided to build a board to serve this role.
The PIC16F15324 was chosen primarily out of familiarity but also for its reasonable specs and capability (relative to this application) and for having no serious errata.

Questions
How big is the SOT23ZenerTester PCB?
It measures 135 × 108 mm and has 4 copper layers, 1.6 mm thick.
What parts does the SOT23ZenerTester use?
81 parts, built around the PDTC123JT, PESD5V0L1UA, 0679L0375-05 and HHXC350ARA680MF80G. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the SOT23ZenerTester KiCad files?
From the slugrustle/electronics repository on GitHub, at the commit this page was made from: the board is SOT23ZenerTester/SOT23ZenerTester.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SOT23ZenerTester design in my own project?
Its repository states no licence, so its author keeps all rights: ask slugrustle before reusing the design.
