Description
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.
