Raspberry Pi Compute Module is quite a popular platform for building commercial or industrial products. If you are looking for the alternatives of Raspberry Pi Compute Module IO board, here is a list of a few low cost development or carrier boards with price information.
I recommend you to also read about the advantages and limitation of Raspberry Pi Compute Module here.
1. Balena Fin Board ($129)
- Built around the Compute Module 3/3+ Lite, a tried-and-true processor with a robust developer ecosystem.
- On-board 8/16/32/64 GB industrial eMMC is more reliable than SD cards
- 6 to 24V range (5V @2.5A via HAT) with barrel jack and phoenix connector. PoE compatible via HAT.
- Dual-band WiFi, Bluetooth, mini PCIe for cellular modems and peripherals, and a SIM card slot
- Embedded 32-bit ARM M4 co-processor allows maximum power efficiency and real-time computing
- Multiple interfaces to fit any use case: Raspberry Pi HAT compatible, HDMI, MIPI, I2C, SPI, UART and GPIO
2. MyPi Industrial IoT Integrator Board (~$135 + IO boards)
- Raspberry Pi Compute Module 1 & 3/3+ compatible
- HDMI, 10/100 Ethernet,2 x USB 2.0 HOST
- Mini PCI-e Interface + SIM connector For use with cellular modems
- Ruggedised High Speed USB based µSD Card interface, providing additional storage separate from the OS file system.
- Integrated USB RS232 UART using RJ45
- Integrated battery backed (RTC)
- 1.6s hardware watchdog
- 8 Way 2 part 3.5mm Phoenix industrial connector for use with Modular IO Card Outputs or HAT board
- Wide 7-24V (poly-fused and filtered) DC power input range
- Core PCB Size : 125 x 142mm
The Compute Module IO Board Plus is a development board which you can plug a Raspberry Pi Compute Module into, and make use of the resources of Pi more flexibly
- Raspberry Pi GPIO header, for connecting sorts of Raspberry Pi HATs
- Arduino connectivity, also supports Arduino shields
- 1-WIRE interface, 4x keys, 4x LEDs, 1x Buzzer, for I/O testing
- Onboard USB HUB, allows connecting more USB devices, Onboard USB TO UART, for serial debugging
- IR receiver, IR remote control is available
- 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

4. Gumstix Pi Compute Dev Board ($55)
Gumstix Pi Compute Dev Board is a complete multimedia expansion board for the Raspberry Pi Compute Module featuring DSI display and CSI2 camera connectors. This board is ideal if you are looking to prototype portable devices and IoT boards with camera and HDMI capabilities
- CSI2 connector to connect the board to a Raspberry Pi Camera using an appropriate ribbon cable
- HDMI type A port
- DSI connector to connect the board to a Raspberry Pi Display using an appropriate ribbon cable
- Dual PWM header
- Micro B USB Plug
- USB 2.0 type A Jack
- 20-pin Header with 16 GPIOs.
Ivport Stereo CM is breakout board that you can plug a Raspberry Pi Compute Modules into.
It comes with two Camera ports, 10/100M Ethernet, dual USB 2.0 ports, Classic Raspberry Pi GPIO header, HDMI output, microSD slot and PoE.
6. Raspberry Pi Compute Module IO Expansion Board ($38.99)
- Raspberry Pi IO expansion board support CM3+, CM3 (build in 4GB NAND Flash), support CM3L (TF card slot has a place to use)
- Support power the board via battery, can read battery capacity by programing
- Support RTC (need to power the board via PH2.0 battery port)
- Support CSI/DSI
- Support OTG interface (via Micro USB Port for data)
7. StereoPi ($89)
StereoPi is an open source stereoscopic camera carrier based on Raspberry Pi Compute Module.
This is by far one of the smallest form factor carrier board for Raspberry Pi compute module. Inspite of small in size, it has various features like:
- Boot mode jumper
- Camera 1 CSI-2 connector
- Micro USB (for firmware upload)
- 5V DC Power Connector
- Power Switch
- MicroSD slot
- RJ45 Ethernet jack
- Dual USB Type-A connector
- HDMI out
- USB port pin header
- Camera 2 CSI-2 connector
- 40-pin RPi GPIO header
- RPi Compute SO-DIMM connector
StereoPi is a carrier board for a Raspberry Pi Compute Module and is compatible with all compute module variants: CM1, CM3 (normal and Lite), and CM3+ (normal and Lite). With Raspberry Pi at its core, StereoPi naturally makes use of standard Raspbian.
