From the project
Custom amateur radio fox hunt (hidden transmitter) controller, aimed at being a flexible, dynamic platform for a wide range of fox-hunt formats — not just a fixed single-mode beacon. Built around an ESP32-S3, u-blox GPS module (MAX-M10S), and SA818S 2m RF module, with a WiFi/BLE
Custom amateur radio fox hunt (hidden transmitter) controller, aimed at being a flexible, dynamic platform for a wide range of fox-hunt formats — not just a fixed single-mode beacon. Built around an ESP32-S3, u-blox GPS module (MAX-M10S), and SA818S 2m RF module, with a WiFi/BLE web UI for configuration and "found" logging, RTOS-based scheduling, RTC-driven wake and precise TX timing, GPS-disciplined timekeeping, and APRS output capability. Firmware developed in PlatformIO. Boards fabricated and assembled via JLCPCB (including their SMT assembly service). Planned as an iterative…

Kicad foxhunt batterytest: common questions
What microcontroller does the Kicad foxhunt batterytest use?
The Kicad foxhunt batterytest is built around the ESP32-S3-WROOM-1-N8R8, from the ESP32 family.
How big is the Kicad foxhunt batterytest PCB?
The Kicad foxhunt batterytest measures 191.5 × 121.8 mm, has 4 copper layers and is 1.61668 mm thick.
How many components are on the Kicad foxhunt batterytest?
253 components, from 118 distinct parts. The full bill of materials is listed on this page.
Where can I download the Kicad foxhunt batterytest design files?
From the gx1400/kicad_foxhunt_batterytest repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Kicad foxhunt batterytest design in my own project?
The repository has no license, so all rights stay with gx1400. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Kicad foxhunt batterytest without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
