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 includes:

• Compute Module 3: Raspberry Pi 3 industrial version, the Pi in a flexible form factor, with 4GB eMMC Flash
• Compute Module IO Board Plus: Extend kinds of interfaces from CM3, such as USB, HDMI, just like the regular Pi, to help evaluating

CM3/CM3L Features

• BCM2837
  • 64-bit 1.2GHz quad-core ARM Cortex-A53 processor
• 1GB RAM
• 4GB eMMC Flash (for CM3 only, not for CM3L)
• 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 pin on CM3 has been used for 4GB eMMC Flash)
  • 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/CM3L 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
