README

A lighting and fan control system for campervans (or anything else)
vandal is an ESP32-based 10-channel smart switch module with LoRa, CANBus, a display, and a rotary encoder. For 12-24V DC systems, intended to control camper or RV lighting. It features
- 7 switched-positive output channels, capable of each sourcing 5A at Vin (up to 27V) . All channels support fade, blink, breathe modes via an SX1509 driver.
- 3 switched-negative channels, capable of each sinking 200mA at up to 30V.
- 6 protected IO lines, 5V-tolerant and operating at a 3.3V logic level
- CANBus interface (via a SN65HVD230 transceiver)
- Protected 1Wire bus, operating at 5V, for temperature sensors (DS1820B and others)
- LoRa transceiver (HopeRF RFM95) with SMA antenna connection
- USB programming for the ESP32 (using a FT232R)
- Numeric/text display: footprints and headers to support 2x Adafruit 0.54" LED backpacks
- 8x32 LED matrix: footprints and headers to support 4x MAX7219-based 8x8 LED arrays Amazon AliExpress 1 AliExpress 2
- Rotary (quadrature) encoder to allow control by the user
- Protected power supply supporting 12V and 24V lead-acid and LiFePO4 battery systems
Protected lines feature diode clamping to 5V and 0V, and high-current lines include TVS diodes on the output to protect against overvoltage and back-EMF. The input has reverse polarity protection. All outputs (and the input) are individually fused.
This project is a work in progress, and the software for the ESP32 doesn't exist yet. It's intended to control LED lighting in my van, and is a bit of an excuse to play with CANBus and the RFM95 LoRa module.
The PCB was created in KiCad. I have a few spare - if you're interested, shoot me an email and I can post you one for a small fee. Alternatively, the gerber files are available here.

Questions
How big is the Van PCB?
It measures 147 × 92 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Van use?
227 parts, built around the ESP32-WROOM-32, SN65HVD230D, FT232RL and BD33IA5WEFJ-E2. 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.
