MinnowBoard.org recently announced the MinnowBoard Max which is a new Intel-powered development board with improved specifications and a $100 lower price versus the original MinnowBoard. The MinnowBoard Max is an open source hardware and software development platform designed and built by CircuitCo with guidance from Intel. The MinnowBoard Max is intended to be used to develop new Bay Trail-powered products or as the brain of embedded equipment that interacts with custom I/O such as FGPAs and specialized sensors.
The MinnowBoard Max is slightly smaller than the original at 2.9” x 3.9” and features an improved Intel Atom processor. Rather than the single core Atom E640 at 1 GHz the original MinnowBoard used, the MinnowBoard Max uses one of two Bay Trail Atom E3800-series SoCs. The base $99 model uses a single core Atom E3815 clocked at 1.46GHz while the $129 model uses a dual core Atom E3825 clocked at 1.33 GHz. The SoC is paired with either 1GB or 2GB of system RAM on the $99 or $129 model respectively.
The MinnowBoard Max supports a wide range of I/O including:
- 26-pin low speed expansion port
- SPI, I2C, I2S Audio, 2 x UARTs (TTL-level), 8 x buffered GPIO (two supporting PWM), +5V, Ground
- 60-pin high speed expansion port
- 1 x PCI-E 2.0 (one lane), 1 x SATA 3Gbps, 1 x USB 2.0 host, I2C, GPIO, JTAG, +5V, Ground
- 1 x USB 3.0 port
- 1 x USB 2.0 port
- 1 x HDMI port
- 1 x Micro SD
- 1 x Gigabit Ethernet
- 1 x Serial Debug (via separately sold cable)
- 1 x Micro USB 2.0
The small form factor board supports Linux and Android operating systems with pending support for the Yocto Project (which helps developers create their own Linux distribution). Intel’s Bay Trail is not open source, but the company has reportedly provided open source drivers for the HD Graphics processor-integrated GPU.
The MinnowBoard Max starts at $99 and is slated to start shipping towards the end of June 2014. MinnowBoar.org will also be releasing the hardware design files under a Creative Commons license shortly after that launch point. More information can be found on the MinnowBoard Max FAQ.
The open source MinnowBoard Max looks to be a respectable upgrade over the original, and the lower price should help to make the x86 architecture more attractive to developers of embedded systems especially in the wake of the proliferation of ARM-powered alternatives.

The Intel Open Source Technology Group along with CircuitCo recently launched a new small form factor bare-bones system based on open source hardware and running open source software. The Minnowboard includes a 4.2” x 4.2” motherboard, passively-cooled processor, rich IO, UEFI BIOS, and the Angstrom Linux operating system.
The Minnowboard is powered by a single core Intel Atom E640 processor clocked at 1GHz. It is a 32-bit CPU with HyperThreading and VT-x virtualization support. Other hardware includes an integrated Intel GMA 600 GPU, 1GB of DDR2 memory, and 4MB of flash memory used for motherboard firmware. Storage can be added by plugging a SSD or HDD into the single SATA II 3Gbps port.
The Minnowboard has following IO options:
- 1 x micro SD
- 1 x SATA II 3Gbps
- 2 x USB 2.0 ports
- 1 x micro USB
- 1 x mini USB (serial connection)
- 1 x RJ45 jack (Gigabit Ethernet)
- 2 x 3.5mm audio jacks (line in and line out)
- 1 x HDMI
The Minnowboard also has a GPIO header with 8 buffered GPIO pins, 2 GPIO LEDs, and 4 GPIO switches. As such, the system can be expanded by adding extra open source modules called “Lures.” The board is aimed at developers and embedded system manufacturers. The Minnowboard can be used as the bare system or can be integrated into a case or larger device.
The Minnowboard costs $199 and is available for purchase now from Digi-Key, Farnell (UK), Mouser, and Newark.
Obviously, the Minnowboard is nowhere near as cheap as the $35 Raspberry Pi, but it is running x86 hardware which may make it worth it to some users.
