Raspberry Pi Compute Module 3+ Lite

Compute Module 3+/Lite (CM3+/Lite), Raspberry Pi 3 Model B+ In A Flexible Form Factor, Without Onboard EMMC Flash

Overview

The CM3+/Lite Compute Module contains the guts of a Raspberry Pi 3 Model B+ (the BCM2837 processor and 1GB RAM). It’s the lite version without onboard eMMC Flash.

This is all integrated onto a small (67.6mm × 31mm) board that fits into a standard DDR2 SODIMM connector. The processor interfaces are available to the user via the connector pins. You get the full flexibility of the BCM2837 SoC (which means that many more GPIOs and interfaces are available than with a standard Raspberry Pi), and designing the Module into a custom system should be relatively straightforward because the Pi Foundation has put all the tricky bits onto the Module itself.

CM3+ Features

• Broadcom BCM2837B0
  • Cortex-A53 (ARMv8) 64-bit SoC @ 1.2GHz
• 1GB RAM
• eMMC Flash
  • CM3+/Lite: None, but brings the SD card interface to the Module pins so a user can wire this up to an eMMC or SD card
  • CM3+/8GB: 8GB
  • CM3+/16GB: 16GB
  • CM3+/32GB: 32GB
• 200PIN SODIMM connector (35U hard gold plating I/O pins)
  • 48 x GPIO
  • 2 x I2C
  • 2 x SPI
  • 2 x UART
  • 2 x SD/SDIO (1x SD has been used for eMMC Flash on non-Lite variants)
  • 1 x HDMI 1.3a
  • 1 x USB2 HOST/OTG
  • 1 x DPI (parallel RGB display)
  • 1 x NAND(SMI)
