GPIO Configuration

User LEDs

LED	GPIO	Active State
LED0	GPIO20	HIGH = ON
LED1	GPIO21	HIGH = ON

Example:

# Turn on LED0
pinctrl set 20 op dh

# Turn off LED0
pinctrl set 20 op dl

Active Buzzer

Parameter	Value
GPIO	GPIO19
Active State	HIGH = Beep

# Activate buzzer
pinctrl set 19 op dh

# Deactivate buzzer
pinctrl set 19 op dl

Digital Inputs

Input	GPIO	Read State
DI0	GPIO22	Read input level
DI1	GPIO27	Read input level

# Read DI0
pinctrl get 22

Digital Outputs

Output	GPIO	Control
DO0	GPIO23	Set HIGH/LOW
DO1	GPIO24	Set HIGH/LOW

# Set DO0 HIGH
pinctrl set 23 op dh

# Set DO0 LOW
pinctrl set 23 op dl

LED Lighting Drivers

Driver	GPIO	Features
L0	GPIO12	PWM capable
L1	GPIO13	PWM capable

The LED drivers support PWM for brightness control. Output voltage follows VIN.

Mini PCIe Module Control

Function	GPIO	Usage
Power	GPIO6	HIGH = Power on
Reset	GPIO5	LOW = Reset (active low)

# Power cycle mPCIe module
pinctrl set 6 op dl  # Power off
sleep 1
pinctrl set 6 op dh  # Power on

# Reset mPCIe module
pinctrl set 5 op dl  # Assert reset
sleep 1
pinctrl set 5 op dh  # Release reset

RS485 Communication

Parameter	Value
Device	/dev/ttyACM0
Max Baud Rate	500 kbps
Direction Control	Automatic
Termination	120 ohm (onboard)

Example using Python:

import serial

ser = serial.Serial('/dev/ttyACM0', 9600, timeout=1)
ser.write(b'Hello RS485\n')
response = ser.readline()
ser.close()

AI Accelerator Setup

Note: Specific AI software stack references are not provided in the official datasheet.

For Raspberry Pi AI HAT+ setup:

1. Install the AI HAT+ hardware (see AI Quickstart)
2. Follow official Raspberry Pi AI HAT+ software installation guides
3. Configure according to your AI application requirements

RTC Configuration

Parameter	Value
Battery Type	CR2032
Function	Maintains time when system is powered off

The RTC is built into the CM5 module. Install a CR2032 battery to maintain time when powered off.

Wireless Configuration

WiFi

Configure using standard Raspberry Pi OS network tools:

# List available networks
nmcli device wifi list

# Connect to network
nmcli device wifi connect "SSID" password "password"

Disabling Wireless

To permanently disable WiFi or Bluetooth, solder the corresponding jumper pads on the internal board:

• WL: WiFi disable
• BT: Bluetooth disable
