+# ESP-WROOM32 with ILI9341 Display Wiring Guide
+
+This board features an ESP32 microcontroller paired with a 2.4" ILI9341 display and supports 5-way button navigation.
+
+## Components
+
+- **MCU**: ESP-WROOM32 (ESP32)
+- **Display**: ILI9341 2.4" SPI TFT LCD (240x320)
+- **buttons**: 5-way tactile button pad (up/down/left/right/select)
+- **LED**: Single status LED
+- **Communication**: SPI for display/radio modules, I2C for sensors
+
+## Display Pinout (ILI9341)
+
+| Display Pin | ESP32 Pin | Purpose |
+|---|---|---|
+| VCC | 3.3V | Power |
+| GND | GND | Ground |
+| CS | 17 | Chip Select |
+| RESET | 5 | Reset |
+| DC | 16 | Data/Command |
+| MOSI | 23 | Serial Data In |
+| MISO | 19 | Serial Data Out |
+| SCK | 18 | Clock |
+| BL/LED | 32 | Backlight (PWM) |
+
+## Button Pinout (5-Way Tactile)
+
+| Button | ESP32 Pin | Function |
+|---|---|---|
+| Select/OK | 35 | Center button |
+| Up | 34 | Navigation up |
+| Down | 26 | Navigation down |
+| Right | 27 | Navigation right |
+| Left | 33 | Navigation left |
+
+All buttons are **active-LOW** (GND when pressed).
+
+## Radio Modules (CC1101/NRF24) - Shared SPI Bus
+
+| Radio Pin | ESP32 Pin | Purpose |
+|---|---|---|
+| VCC | 3.3V | Power |
+| GND | GND | Ground |
+| MOSI | 23 | Serial Data In (shared with display) |
+| MISO | 19 | Serial Data Out (shared with display) |
+| SCK | 18 | Clock (shared with display) |
+| CS | 15 | Chip Select (software selectable) |
+| *Specific to RF module* | | See module documentation |
+
+**Note**: Radio modules share the SPI bus with the display but have separate chip select (CS) lines. The firmware manages CS timing to prevent conflicts.
+
+## I2C Sensors (Grove/Standard)
+
+| Sensor Pin | ESP32 Pin | Purpose |
+|---|---|---|
+| VCC | 3.3V | Power |
+| GND | GND | Ground |
+| SCL | 22 | I2C Clock |
+| SDA | 21 | I2C Data |
+
+## Status LED
+
+| LED Pin | ESP32 Pin | Purpose |
+|---|---|---|
+| Anode | 2 | Active HIGH output |
+| Cathode | GND | Ground |
+
+## Serial Port
+
+| Pin | ESP32 Pin | Type |
+|---|---|---|
+| RX | 3 | UART0 Input (programming/debug) |
+| TX | 1 | UART0 Output (programming/debug) |
+
+## Power Supply
+
+- **Logic voltage**: 3.3V
+- **Supply current**: ~500mA typical (display + MCU)
+- **Peak current**: ~800mA (during radio transmission)
+
+Use a quality USB power supply or regulated 3.3V source rated for at least 1A.
+
+## Wiring Notes
+
+1. **SPI Bus Sharing**: Display, radio, and SD card (if used) all share SCK/MOSI/MISO lines. Each device has its own CS line to prevent conflicts.
+2. **Button Ground**: All 5 buttons should be pulled to GND when pressed. Use 10kΩ pull-up resistors on pins if needed.
+3. **Backlight**: The BL pin (GPIO32) supports PWM for brightness control (0-255).
+4. **Reset**: The display RESET (GPIO5) is active LOW. Normally tied HIGH through 10kΩ resistor.
+5. **Debouncing**: The firmware handles software debouncing for buttons (typical bounce time ~20ms).
