KOTH V2 is an open source AVR/Arduino PCB design by Salted-Peanuts: a 4-layer, 100 × 100 mm board with 41 components (23 distinct parts). It is built around the 5V_STEP_UP, ARDUINO_NANO_ESP32. Filed under iot & wireless and displays & leds.

DIY Arduino Nano ESP32 King of the Hill timer for Nerf, foam flinging, skirmish games, and objective-based events. Includes build guide, firmware, BOM, schematic, and phone referee UI.

This folder contains the second PCB revision for the KOTH Timer.

Manufactured, assembled, and tested with no known faults.

PCB v0.2 is the current recommended PCB revision for new builds.

PCB v0.2 was redesigned after testing PCB v0.1.

The v0.1 board was functionally usable through the web UI, but some TM1637 displays showed reliability issues.

PCB v0.2 improves the design with better attention to:
