# Wiring
This document describes the current planned wiring for the Overland Controller install.
This document contains older wiring notes and may include legacy Pico/UART dashboard assumptions.
The current system uses:
Current dashboard and hardware source of truth:
- ESP32 2-relay controller board
- Raspberry Pi Pico 2 W dashboard
- CAT5/CAT6 cable between rear controller and dash
- 12V-to-5V buck converter in the dash enclosure
- `docs/HARDWARE.md`
- `docs/dashboard-esp32s3.md`
Do not use Pico-specific wiring in this file for the current dashboard build.
Current planned system uses:
- Cargo ESP32 2-relay controller board
- Waveshare ESP32-S3-Touch-LCD-5 dashboard over WiFi/HTTP
- ACC switched 12V fused dashboard power into Waveshare VIN
- DS18B20 temperature sensors
- JBD/Xiaoxiang BMS over BLE
- External automotive relays for high-current loads
- External fused automotive relays or contactors for major loads
