MinnowBoard Turbot open source hardware SBC was released in 2015 with an Intel Atom E3826 dual core Bay Trail-I processor, 2GB RAM, SATA and Gigabit Ethernet support, and a new version – MinnowBoard Turbot Quad – with a more powerful quad core processor, an heatsink and fan, and better Ethernet connectivity will be launched in December.
MinnowBoard Turbot Quad “MBT-4210” board specifications:
- SoC – Intel Atom E3845 quad core Bay Trail-I processor @ 1.92 GHz with Intel HD graphics @ 542 / 792 MHz (10W TDP)
- System Memory – 2GB DDR3L 1067 MT/s (Soldered)
- Storage – 1x SATA2 3Gbs, 1x micro SD card slot, , 8 MB SPI Flash for firmware (Tianocore UEFI, Coreboot, SeaBIOS)
- Video & Audio Output – 1x micro HDMI connector
- Connectivity – 10/100/1000M Ethernet RJ-45 connector (Intel i211 instead of Realtek NIC on first board)
- USB – 1x USB 3.0 host, 1x USB 2.0 host
- Debugging – Serial debug via FTDI cable, firmware flash port header
- Expansion headers
- Low-speed expansion (LSE) port – 2×13 (26-pin) male 0.1″ pin header with access to SPI, I2C, I2S Audio, 2x UARTs (TTL-level), 8x GPIO (including 2x supporting PWM), +5V, and GND
- High-speed expansion (HSE) port – 60-pin high-density connector with access to 1x PCIe Gen 2.0 Lane, 1x SATA2, 1x USB 2.0 host, I2C, GPIO, JTAG, +5V, and GND
- 8x buffered GPIO
- Power Supply – 5V/4A DC input via 2.5mm center pin positive power jack; 5V DC output via 2-pin header
- Dimensions – 99 x 74mm
- Temperature Range – Operating: TBD; Storage: -20 to +85 deg C
- Certifications – FCC Class B, CE, IEC-60950, RoHS/WEEE
The company claims the new processor is 2.5 times faster than the dual core processor used in the first board, likely referring to multi-core performance at a higher clock speed, and the fansink should make it more suitable for higher temperature applications. Gigabit Ethernet is also supposed to benefit from replacing a Realtek GbE controller by Intel i211.
The board leverages MinnowBoard MAX ecosystem, with support for many different operating systems including Debian GNU/Linux, Brillo, Windows 8.1 / 10, Android 4.4, and Ubuntu. MinnowBoard Turbot (Quad) is also compatible with the Yocto Project, 64-bit Intel firmware, Coreboot and U-boot, and more with details available on Minnowboard Wiki. The board will be open source hardware with the files released under a Creative Commons BY-SA 3.0 license. The hardware should not be that different from MinnowBoard Turbot (dual core) whose schematics, PCB layout, gerber files, and BoM can be found on MinnowBoard Turbot Wiki.
The board can be pre-ordered for $189.95 on Netgate, but you may consider adding accessories like a metal case (+$19), 5V/2A or 4A power supply ($10.95/$12.95), and/or a HDMI cable ($9.995). Bear in mind that shipping is only scheduled for December 2016.
