Overview

Since the Raspberry Pi Foundation released the Compute Module 3+, you may have been watching it for some time, don't know how to get started. Now it's time to get moving. We prepare this development kit for you to evaluate the Compute Module 3+ quickly, reducing your development cycle.

The key parts in this Compute Module 3+ development kit are:

• Compute Module 3+ (optional): Raspberry Pi 3 Model B+ industrial version, the Pi in a flexible form factor, with multi eMMC options, you can also choose to buy the kit without a compute module
• Compute Module IO Board Plus: Extend kinds of interfaces from CM3+, such as USB, HDMI, just like the regular Pi, to help evaluating

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)
  • 1 x 4-lane CSI Camera Interface (up to 1Gbps per lane)
  • 1 x 2-lane CSI Camera Interface (up to 1Gbps per lane)
  • 1 x 4-lane DSI Display Interface (up to 1Gbps per lane)
  • 1 x 2-lane DSI Display Interface (up to 1Gbps per lane)
• Compared to CM1, the CM3+ supports more OS, like Windows 10 (the free IOT-specific version from Microsoft)

Compute Module IO Board Plus Features

• Compatible with the Compute Module IO Board V3 from the Raspberry Pi Foundation
• Raspberry Pi GPIO header, for connecting sorts of Raspberry Pi HATs
• Arduino connectivity, also supports Arduino shields
• 1-WIRE interface, for connecting single-bus devices like DS18B20
• 4x keys, 4x LEDs, 1x Buzzer, for I/O testing
• Onboard USB HUB, allows connecting more USB devices
• IR receiver, IR remote control is available
• Onboard USB TO UART, for serial debugging
• Sensor interface
• 10-bit ADC, 38KSPS, 11-ch (6-ch for Arduino interface, 5-ch for sensors)
• 16-bit DAC, 2-ch
• Onboard RTC, one of the most common and useful functions
