This page describes Wiren Board rev. 2.8 (first public revision).
Ниже дано описание Wiren Board версии 2.8 (первая версия поступившая в продажу).


The Wiren Board consists of two PCBs:
Wiren Board состоит из двух печатных плат:


* Olinuxino imx233-Micro with power capacitors, TV out jack, power jack and USB jack desoldered. At present, original Olinuxino imx233-MICRO manufactured by Olimex is used. Most of the rev. 2.8 Wiren Board's are equiped with rev. C Olinuxino's. This board contains CPU ([[Freescale i.MX233]]) and RAM.
* Olinuxino imx233-Micro без TV штекера, разъема питания и USB, конденсаторов питания (отпаяны для уменьшения габаритов). Сейчас используеются оригинальные платы произведенные [Olimex]. бльшинство Wiren Board версии 2.8 используют плату Olinuxino версии C. Это плата содержит CPU ([[Freescale i.MX233]]) и RAM.
* Main Wiren Board PCB manufactured by Contactless Devices, LLC.   
* Основная плата Wiren Board разработана Contactless Devices, LLC.   




The main PCB contains:
Основная плата содержит:
* power management circuit based on [[LTC4002]] chip.  
* Схема питания на чипе [[LTC4002]].  
* USB to Ethernet converter and USB hub, SMSC [[LAN9514]]
* USB to Ethernet конвертер и USB хаб, SMSC [[LAN9514]]
* USB Wi-Fi [[RTL8188_assembly|micro assembly] based on Realtek [[RTL8188]] chip.
* USB Wi-Fi [[RTL8188_assembly|micro assembly] на основе чипа Realtek [[RTL8188]] .
* NFC circuit based on NXP [[PN532]]. There is also trace antenna for NFC on the PCB. See also [[NFC Subsystem]].
* NFC circuit based on NXP [[PN532]]. There is also trace antenna for NFC on the PCB. See also [[NFC Subsystem]].
* Analog multiplexer for multiplexing 8 ADC channels (7 terminal blocks and Vin). See also [[ADC]].
* Analog multiplexer for multiplexing 8 ADC channels (7 terminal blocks and Vin). See also [[ADC]].
