Banana Pi R2 Open Source Wireless Router
The Banana Pi R2 is a router-based development board, which can run on a variety of open-source operating systems including OpenWrt, Android, and Bananian. It has 4 Gigabit LAN ports, 1 Gigabit, WAN, and 300 MBs wireless N capabilities. Banana Pi is an open platform device, it is for anyone who wants to play and build its customized platform based on open-source development technology, instead of simply using consumer technology.
Banana Pi welcomes all companies, DIYers, and tech-loving people to join their community and start building practical projects for home or commercial applications that will be low power consumption and also cost-effective.

Package Content
The default package only contains the R2 router board that costs $89.50 and above, depending on the selected postage service selected. To power the board you will also need to buy a 12V/2A adapter. Other accessories such as plastic or metal made In my personal experience FromFor this review my personal experience are also optional, but not a “must have” item.
Banana PI R2 Case
Composed of two parts. The upper cover is made from plastic and the base is made from bent sheet metal. If you’re planning on installing a Heatsink with a fan, you. from my personal experience, the case quality is excellent, and I was impressed with the design and build quality. The case lake has some ventilation holes. SINOVOIP could have added a few venting slots on both sides of the case to let the extra hot air out of the case. If you decide to buy the case, you will need to add a few by drilling or melting the plastic using a soldering/welding Iron Tool.
The case package contains all necessary screws, and legs, including a pair of data and power cables to connect two 2.5-inch hard drives that are also mounted using the provided screws. if you need to access the GPIO Header pins and other external interfaces it’s best to close the upper cover with the screws for easy opening when needed.
Additional Cooling (Optional)
If you planning on installing a heatsink with a fan you also have an additional 5V power connector option on the R2 board you can use. For this review, I used a few aluminum heat sinks, purchased from SINOVIP AliExpressFor this review which covers the CPU chip as well as the ram memory chipsx1, Mini.
Adding WiFi Antennas (Optional)
Although, there are two holes within the case cover for mounting a pair of external WiFi Antennas with RP-SMA connectors, in his Board you can only use just one because this case was initially designed for an R1 board that has two onboard sockets because the R2 you only have one onboard antenna slot it’s not relevant, therefore you can only use one antenna.
Antenna Items/elements:
- x1 Mini gold plated coaxial cable RP-SMA to U.Fl
- x1- Gold-plated lock nuts.
- x1 3db gain router omnidirectional 2.4 GHz dipole antenna with 3 swivel positions 45, 90, and 180 degrees

A Closer Look at the Banana Pi R2
The R2 Board is powered by a Cortex-A7 quad-core Mediatek MT7623N processor. It comes with 2GB of RAM, 8GB EMMC onboard storage, x1, Micro-SD Card socket, x2 USB 3.0 ports, HDMI 1.4V port, A pair of SATA 3.0 interfaces, and 5V power plugs for connecting two 2.5″ hard drives.
As for other onboard external interfaces. You have an IR Receiver, 40 Pin GPIO header Interface, Debug UART port, MIPI DSI, and a USB OTG port that is used mainly for flashing firmware to the device’s EMMC chip. The only missing interface this board was missing is the popular CSI (Camera Serial Interface) and external battery backup interface that exists in the older R1 board.
Having said that, the main highlights of this board are definitely the SATA V3.0 interfaces, onboard WiFi support, 1 Gigabit WAN and 4 Gigabit LAN Ethernet ports, and the fact that you can use the Mini PCIe interface to add a cellular modem card with 3G/4G support via A SIM Card. With all of those features in one device, the R2 can be used for a wide scale of applications. For example, building a flexible open source-based router that also functions as a NAS which can be used to share multimedia content across a local or remote network.

Software Support
OpenWrt
OpenWrt is an open-source project for an embedded operating system based on Linux, primarily used on embedded devices to route network traffic. Unfortunately, Sinovoip R2 images currently do not have HDMI interface support so you basically get a useless blank screen and can’t use the board to an external monitor and see what you’re actually doing. If you still want to make the OpenWrt image workable to adjust all settings with the R2 Board the only solution is buying a USB to UART converter to connect to the board directly.
Other Linux Distributions
From my personal general impression, Ubuntu and Fedora Images I have tested worked smoothly with WiFi and LAN adaptors configured properly. Also, Raspbian Jessie which is a lightweight Debian distribution also worked very smoothly as expected.

Final Words
The R2 is a nice board with good accessories packed with lots of interfaces you can use for various open-source DIY projects. It runs on Ubuntu, Debian, and other distributions pretty well. What I was missing as a user were two types of images that could have made this product perfect, or almost perfect. As a user, I felt too complex and time-consuming to configure the OpenWrt to work with this board, especially when the HDMI interface doesn’t work and just outputs a black screen.
In addition, OpenMediaVault image support was not available, which could have added extra value to this product, making it much easier to set it as a type of home/office NAS device. If you sum up all the cons and pros this board has to offer, it has many functions and values. especially if you are planning to add one or two internal SSD drives vs. Just connecting them externally via a USB interface. Bottom line, I recommend the product and hope that soon SinoVoip will fix the OpenWrt image and provide OpenMediaVault support.
