We all knew Raspberry Pi Compute Module 3 were about to be launched soon, as the Raspberry Pi foundation announced a partnership with NEC displays last October, and the datasheet for two version of the Broadcom BCM2837 based system-on-module, CM3 and CM3L (Light), was released shortly after. The good news is that the modules have officially been launched for $30 and $25 for respectively Compute Module 3 with 4GB flash, and Compute Module 3 Light with the SD card signals exposed via the SO-DIMM connector. The foundation has also lowered the original compute module price to $25.
- SoC – Broadcom BCM2837 quad core Cortex A53 processor @ 1.2 GHz with Videocore IV GPU
- System Memory – 1GB LPDDR2
- CM3L – SD card signals through SO-DIMM connector
- CM3 – 4GB eMMC flash
- 200-pin edge connector with:
- 48x GPIO
- 2x I2C, 2x SPI, 2x UART
- 2x SD/SDIO, 1x NAND interface (SMI)
- 1x HDMI 1.3a
- 1x USB 2.0 HOST/OTG
- 1x DPI (Parallel RGB Display)
- 1x 4-lane CSI Camera Interface (up to 1Gbps per lane), 1x 2-lane CSI Camera Interface (up to 1Gbps per lane)
- 1x 4-lane DSI Display Interface (up to 1Gbps per lane), 1x 2-lane DSI Display Interface (up to 1Gbps per lane)
- Power Supply – VBAT (2.5V to 5.0V) for BCM2837 processor core, 3.3V for PHYs, UI and eMMC flash, 1.8V for PHYs, IO, and SDRAM, VDAC (2.8V typ.) for video composite DAC, GPIO0-27_VREF & GPIO28-45_VREF (1.8 to 3.3V) for the two GPIO banks.
- Dimensions – 67.6 x 31 mm; compliant with JEDEC MO-224 mechanical specification used in DDR2 SO-DIMM memory module
- Temperature Range – -25 to +80 degrees Celsius
The module is mostly electrically & mechanically backward compatible with the original Compute Module, and benefits from the software running on Raspberry Pi 3 board. You’ll find specific documentation here.
In order to get started quickly, a Raspberry Pi Compute Module 3 devkit is also offered with a CM3 module and a “Compute Module IO V3” baseboard exposing GPIO headers, an HDMI port, a USB port, a micro SD slot, and more.
