背景

Radxa 项目团队介绍.

Radxa 是一个创业型公司,由Tom Cubie 带领的团队 于2013年在深圳创办

常见问题

从哪里获取代码

两种方法
1. 从我们的git服务器上获取,参考wiki Get_the_source_code (注: 需要申请git账号,方法是发送申请邮件到 support@radxa.com)
2. 从这里下载git repo: http://dl.radxa.com/rock/source/radxa_rock_android.tar.gz 下载解压后在文件根目录运行 git checkout(注:不需要申请账号)

OTG线 和 电源的规格

标准的micro USB OTG 线即可,电源推荐 5V/2A

Radxa能否当AP使用

可以. Radxa 使用了两种wifi芯片RTL8723au 和RTL8188ETV
1.RTL8723au拿来用做AP,网上的相关信息很少.这里有一个关于该模组的资料介绍可以参考: RTL8723 module specification.
驱动可以从这里获得: https://github.com/lwfinger/rtl8723au.
2.RTL8188ETV, 其驱动可以在这里获得: https://github.com/lwfinger/rtl8188eu.

Radxa Rock的尺寸是多少?

10x8cm (4"x3.1"), 1.2cm (0.5") 高.

Are both audio in and out on the 80 pin?

Audio in is on the 80 pin headers and audio out is on the HDMI, S/PDIF and AV jack.
There is also an integrated microphone on the PCB.

Radxa Rock 支持哪些音视频格式

参考文档,这里有详细介绍 http://dl.radxa.com/rock/docs/hw/ds/RK3188%20Multimedia%20Codec%20Benchmark.pdf

Radxa Rock has Audio S/PDIF out, optical. Is it sound 5.1 (7.1)?

From the rk3188 manual, the spdif feature is:
SPDIF
Audio resolution: 16bits/20bits/24bits
Software configurable sample rates (48KHz, 44.1KHz, 32KHz)
Stereo voice replay with 2 channels
so it's not 5.1 audio.

Radxa Rock 上的RTC (Real-Time Clock)电池规格?

3V CR1220

为什么Android在运行的时候老是重启 或者在运行相关应用的时候(Gmail,安兔兔等)重启

这是由于供电不足导致,请使用5V/2A的直流电源供电
