Piunora Lite Carrier for Raspberry Pi 4 Module by Diodes Delight

Piunora by Diode Delights is a compact, easy-to-use development board for electronics prototyping with Linux. Designed as a carrier board for the Raspberry Pi Compute Module 4 (CM4), it offers a familiar Arduino UNO R3 / Adafruit Metro compatible form factor and is optimized for space-constrained applications.

Piunora Lite uses the same PCB as Piunora Pro with bottom side components removed for space and cost savings. Note that Piunora Lite does not include the PCI-e M.2 B-Key connector or the camera connector found on the Pro version.

Key features include:

• Arduino UNO R3 / Adafruit Metro compatible form factor (3.3 V logic)
• Analog to Digital Converter (MCP3008)
• On-the-fly switching between USB host (USB Type-A) and device mode (USB Type-C)
• Qwiic/Stemma QT connector for easy I²C device interfacing
• Full-sized HDMI 2.0 port
• WS2812 Smart RGB LED for user status
• Slim design measuring 8-12 mm thickness
• Two user-controllable buttons including software enabled safe-shutdown
• Open hardware with published design files and software

Note: Raspberry Pi 4 Compute Module is not included but available separately.
