SeeedStudio BeagleBone Green Wireless is a joint effort by BeagleBoard.org and Seeed Studio. Based on the open-source hardware design of BeagleBone Black, the newest BBGW has added two Grove connectors, making it easier to connect to the large family of Grove sensors. It is the first Wi-Fi + Bluetooth Low Energy (BLE) board from BeagleBone community.
Raspberry Pi is well known as the perfect board for learning, coding, and creating your own projects. In celebration of The Raspberry Pi Foundation fourth birthday, Raspberry Pi 3 is released.
The Raspberry Pi 3 has included integrated 802.11 b/g/n wireless LAN, Bluetooth Classical and LE. You didn’t need additional peripherals to make it wireless. It is 10x the performance of Raspberry Pi 1.
What’s more, it has complete compatibility with Raspberry Pi 2, which means almost all the previous Raspberry Pi 2 accessories are compatible with Raspberry Pi 3.
The Raspberry Pi 3 is the third generation Raspberry Pi. It replaced the Raspberry Pi 2 Model B in February 2016. Compared to the Raspberry Pi 2 it has:
- A 1.2GHz 64-bit quad-core ARMv8 CPU
- 802.11n Wireless LAN
- Bluetooth 4.0
- Bluetooth Low Energy (BLE)
Like the Pi 2, it also has:
- 4 USB ports
- 40 GPIO pins
- Full HDMI port
- Ethernet port
- Combined 3.5mm audio jack and composite video
- Camera interface (CSI)
- Display interface (DSI)
- Micro SD card slot (now push-pull rather than push-push)
- VideoCore IV 3D graphics core
The Raspberry Pi 3 has an identical form factor to the previous Pi 2 (and Pi 1 Model B+) and has complete compatibility with Raspberry Pi 1 and 2.
Please visit our Wiki page for more information about this product. It will be much appreciated if you can help improve the documents, add more demo codes or tutorials. For technical support, please post your questions to our Forum.
All the existing Raspberry Pi 2 accessories and kits are fully compatible with the Raspberry Pi 3.

A ceramic chip antenna is used by WiFi and Bluetooth 4.1 SoC BCM43438. The chip antenna moves the indicator LEDs that were present in Pi 2 to the lower side of PCB.
The ACT and PWR LEDs are repositioned as shown below in Raspberry Pi 3 when compared to Pi 2.
