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. It has a familiar form factor, legible pin labels, and a design that’s well suited to space-constrained applications.

As a carrier board for the Raspberry Pi Compute Module 4 (CM4), Piunora is essentially a tiny version of the Raspberry Pi 4 Single Board Computer (SBC) with added flexibility to accommodate custom form factors. CM4-based devices like Piunora are fully compatible with software that was written for the Raspberry Pi 4, as long as that software accounts for the hardware peripherals in use. There are also versions of the CM4 that include eMMC memory, which is more reliable than a traditional SD card.

It may be small, but Piunora is packed with powerful peripherals!

Piunora Lite uses the exact same PCB as Piunora Pro but leaves off the bottom side components for space and cost savings.

Piunora Lite does not include the following features:

• PCI-e M.2 B-Key with dedicated 3.3 V / 3 A supply.
• Camera connector

Features & Specifications

• Arduino UNO R3 / Adafruit Metro compatible form factor (3.3 V logic, may not be compatible with all Shields)
• PCI-e through M.2 B-Key connector on the rear of the board with dedicated 3.3 V / 3 A supply
• 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 to easily interface with I²C devices
• A full-sized camera connector that supports all Pi-compatible cameras
• A full-sized HDMI 2.0 port
• A WS2812 Smart RGB LED for user status
• Optional Wi-Fi or eMMC options depending on your choice of CM4
• Slim design with the Piunora Lite measuring 8-12 mm and the Piunora Pro measuring 11-13 mm
• Two user-controllable buttons (including software that turns one of them into a safe-shutdown button)
• Open hardware. Design files and software are published by the time it ships

Pi 4 Compute Module is not included, but we carry them here.
