Banana Pi BPI-M1

Introduction

The Banana Pi BPI-M1 is a business card-sized and low-power single-board computer featuring a high performance AllWinner A20 dual-core SoC at 1 GHz, 1 GB of DDR3 SDRAM, Gigabit Ethernet, SATA, USB, and HDMI connections. It can run a variety of operating systems including Android, Lubuntu, Ubuntu, Debian, and Raspbian.

The BPI-M1 is our first product in our goal of creating an open source devlopment board community. With a Banana Pi, we want you to explore and experience the world of DIY projects and portable computing. 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.

Banana Pi is an open platform device, it is for anyone who wants to play and build with developer technology instead of simply using consumer technology. Backed by our community, starting a project and building servers is fun and rewarding.

• • UART specification:**

The jumper J11 is the UART interface. For developers of Banana Pi, this is an easy way to get the UART console output to check the system status and log message.
