Introduction

Overview

Overview: R40 chip

Banana Pi BPI-M2 Ultra is a quad-core mini single board computer built with Allwinner R40/V40 SoC. It features 2GB of RAM and 8GB eMMC. It also has onboard WiFi and BT. On the ports side, the BPI-M2 Ultra has 2 USB A 2.0 ports, 1 USB OTG port, 1 HDMI port, 1 audio jack, a DC power port, and last but not least, a SATA port.. Also being a member of the Banana Pi family, the M2 Ultra is a direct upgrade from the Banana Pi M1/M1+ that support SATA from the SoC. The SATA performance on the R40 is fitting for media related projects such as storage servers. Backed by our community, starting a project and building servers is fun and rewarding. We welcome all companies, DIYers, and tech loving people within our community! Together, we can make a difference, we can discover our passions, inspire others, and build a practical project.
