拆解 Kensington 2.4G 无线激光鼠标
下班,回到宿舍,立刻取出螺丝刀,拆解这个便宜的无线激光老鼠。

拆开接收器。


可以看到无限接收器使用的是NRF 2401AG 芯片,还有一个处理芯片,可惜照片没有拍好,看不清上面写的是什么型号。GOOGLE查到的芯片信息是:“挪威Nordic Semiconductor公司制造的无线接收IC”
拆解鼠标

鼠标背面,
没什么奇特的地方,唯一比较漂亮的就是这个通光孔,和一般的光电鼠标不一样,使用过程中,这里是看不到任何光线射出的,推断使用的是红外激光发射管。

拆开外壳,
可以看到里面使用了4层电路板,依次又上到下是:2.4G发射模块,侧面3扩展按钮电路板,左右键滚轮按钮控制板,最下面的是主电路板。

2.4G模块,
我们可以看出他使用的无线传输芯片是NRF B 2402G,通过GOOGLE可以查到此芯片的信息是:“挪威Nordic Semiconductor公司制造的无线发送IC”
nRF2402 Transmitter
- The Nordic Semiconductor nRF2402 ultralow power 2.4GHz transmitter
GENERAL DESCRIPTION
nRF2402 is the Industry's smallest, lowest cost, lowest current consumption and low voltage supply 2.4GHz RF transmitter. It provides global wireless equipment vendors with global 2.4GHz technology at the price and complexity of lower frequencies. The nRF2402, ideally complements the higly successfulnRF2401 transceiver offering vendors with unidirectional equipment a lower cost alternative. The nRF2402 is a highly integrated component for wireless communication manufactured in an ultra modern 0.18mm CMOS process. The entire transmitter including all inductors and filters is integrated in a single chip that gives the lowest cost solution to the end user. The only external components needed to make a complete RF system is a crystal and a resistor. Current consumption is around 10mA in transmit mode @ -5dBm. The total solution fits into a 4x4mm package. The nRF2401 is designed for wireless transmitter applications in wireless game controllers, PC peripherals, wireless headsets, sports and leisure equipment, toys, RF-ID, remote control, and interactive equipment. All configuration of the nRF2402 transmitter is done via a standard serial interface. nRF2402 can replace IR and typical 27MHz communication in most applications. An innovative embedded feature in nRF2402 to reduce cost and current consumption is "ShockBurst" which uses an onboard FIFO to buffer up data and transmit in bursts, as well as dedicated on chip logic to compute the CRC checksum.

背面,写有Kensington 的版权字样,不过出现的2005字样,让我不爽,这说明此鼠标2005年就已经面世了。

光电转换处理器,
可以看到,这个老鼠使用的是安捷伦的A6030 IC。GOOGLE查找到的这个IC的资料:“A6030(激光鼠标用)”“安捷伦A6030被应用于高端无线鼠标上,分辨率为800DPI ,7080帧/秒的扫描速率,20G移动加速度。”
根据侧面查看,和公布的激光鼠标结构图一致。入下图

Agilent ADNK-6030 光学鼠标模组
可惜的是VISTA系统下,此鼠标的驱动不能用,仍在继续寻找中。
贴个XP下的驱动程序设置图吧。

至此,基本可以判定,这个鼠标确实是2.4G无线激光鼠标,对于这个不到100人民币的鼠标来说,性价比很高。

nRF2401A Transceiver
- The Nordic Semiconductor nRF2401A ultralow power 2.4GHz transceiver
GENERAL DESCRIPTION
nRF2401A is the Industry's smallest, lowest cost, lowest current consumption and low voltage supply 2.4GHz RF transceiver. It provides global wireless equipment vendors with global 2.4GHz transceiver technology at the price and complexity of lower frequencies. The nRF2401A is a highly integrated component for wireless communication manufactured in an ultra modern 0.18µm CMOS process. The entire transceiver including all inductors and filters is integrated in a single chip that gives the lowest cost solution to the end user. The only external components needed to make a complete RF system is a crystal and a resistor. Maximum current consumption is less than 18mA in receive mode, and 10.5mA in transmit mode @ -5dBm. The total solution fits into a 5x5mm package. The nRF2401A is designed for wireless transceiver applications in wireless game controllers, PC peripherals, wireless headsets, sports and leisure equipment, toys, RF-ID, remote control, and interactive equipment. All configuration of the nRF2401A transceiver is done via a standard serial interface. nRF2401 can replace IR and typical 27MHz communication in most applications. Innovative embedded features in nRF2401 to reduce cost and current consumption "DuoCeiver" and "ShockBurst" The nRF2401A the receiver can receive on 2 channels simultaneously, for example from a wireless mouse and keyboard. This eliminates the need for adding 2 separate RX modules, so costs are halved and space is saved.
A "green" Pb (lead) free alternative
The nRF2401A is offered in a "green" lead free alternative - the nRF2401AG - and confirms to current and future environmental standards. For more info, please go to Nordic Semiconductor Green/Pb Free Program.

Kensington 无线激光鼠标到手
Eee PC 之我见

下载kensington mousework 6.2.2
解压到硬盘的某个文件夹下,记住路径。
找到解压文件夹中的setup.exe,
反键,属性,兼容性勾选使用windows xp Sp2
在控制面板里找到鼠标,打开在硬件里找到hid-compliantmouse, 单选,属性,然后更新驱动程序
选择后者,找到刚才解压的文件夹MW_PC_622
安装成功后会显示kensington HID laser
再安装setup.exe 重启后就可以正确识别鼠标并设置功能键了。
