ESP32 Geiger Counter PCB
ESP32 · Altium Designer · PCB design · Power electronics
This is what I am working on right now: an ESP32-based Geiger counter PCB, from power architecture and high-voltage interfacing through Altium layout and planned validation before assembly and firmware bring-up.
Overview
My current build is a full embedded hardware project: an ESP32 Geiger counter PCB that ties together battery charging, regulated rails for the microcontroller, Geiger tube sensor interfacing, and external high-voltage generation. The focus is a reliable system-level power architecture and a board layout ready for validation before assembly and firmware testing.
What I'm doing
- ·Laid out a manufacturable ESP32 Geiger counter board in Altium by integrating charging, regulation, sensor interfacing, and high-voltage subsystem connections on one PCB.
- ·Defined the full power path—USB charging, Li-ion management, ESP32 rails, and external high-voltage generation—so subsystems have a clear, testable architecture.
- ·Picked parts for charging, regulation, USB, and control with integration and manufacturability in mind, not just schematic correctness.
- ·Planned bring-up tests for charger output, regulated rails, ESP32 power stability, and subsystem integration before I solder the board and start firmware work.
