Latest HummingBoard SBC adds CAN and serial ports

Dec 26, 2018 — by Eric Brown 1,567 views

SolidRun has launched a variation on the HummingBoard Edge SBC called the HummingBoard CBi that swaps the HDMI port with CAN and serial ports and similarly runs Linux on an i.MX6 MicroSOM.

SolidRun has introduced a HummingBoard CBi spin-off of its earlier HummingBoard Edge SBC that adds CAN and serial ports. The sandwich-style board, which ships with a standard enclosure, has the same 102 x 69mm footprint of the Edge and the HummingBoard-Gate and ships with open schematics.

The HummingBoard CBi SBC/mini-PC runs Linux on the same NXP i.MX6 equipped MicroSOM modules with dual-or quad-core 1.2GHz Cortex-A9 cores. (A single-core Solo model is listed in the specs, but not yet available.) Debian, Yocto Project, BuildRoot, and OpenWrt stacks are available with a Linux 4.4x kernel, and Android support is in the works.

The HummingBoard CBi offers a standard enclosure, heatsink, and -40 to 85°C support — features that are optional on the Edge. The dual-core version costs $189 with 1GB RAM (compared to $233 for a similarly configured Edge) and $255 for the quad-core model with 2GB, the same as an equivalent Edge.



The CBi lacks the HDMI port of the Edge, and there’s no mention of the GPIO header. However, it adds CAN and RS485 ports via terminal connectors and adds a configurable push button and LEDs.

Other features appear to be identical, including the usual bandwidth-limited GbE port, 4x USB 2.0 ports, 8GB eMMC, and a microSD slot. Although it’s not listed on the product page, the shopping page says the board provides a WiFi/Bluetooth module.

Like the Edge, the CBi offers a mini-PCIe slot with SIM slot, as well as a storage-ready M.2 slot. Other features include LVDS, MIPI-DSI, and MIPI-CSI interfaces, as well as an RTC and a wide-range 7-36V input.

  • Processor (via MicroSOM i.MX6) – NXP i.MX6 (2x or 4x Cortex-A9 cores @ up to 1.2GHz)
