Are you a Java developer looking to add advanced hardware I/O capabilities to your Android or PC application? Well then the IOIO-OTG is for you! The IOIO-OTG (pronounced “yo-yo-O-T-G”) is a development board specially designed to do just that. It features a PIC microcontroller which acts like a bridge that connects an app on your PC or Android device to low-level peripherals like GPIO, PWM, ADC, I²C, SPI, and UART. An app-level library helps you write control code for these low level peripherals in the same way you’d write any other Java app!

What separates the IOIO-OTG from previous IOIO boards is the ability to leverage the USB On-The-Go specification to connect as a host or an accessory. There are several ways to connect the IOIO to your Java app. If the app is running on your Android device, the IOIO-OTG will act as a USB host and supply charging current to your device (meaning the IOIO-OTG will need its own power source). If your app is running on a Windows, Linux or OSX machine, the IOIO-OTG will assume device mode and present itself as a virtual serial port. When in device mode, the IOIO-OTG can be powered by the host! Connecting a USB Bluetooth dongle will cause the IOIO-OTG to show up as a Bluetooth serial connection so you can go wireless!

A switch on the board can be used to force the IOIO-OTG into host mode, but most of the time the board can be left in ‘auto’ mode and it will detect its role in the connection. We’re now shipping the IOIO-OTG board loaded with the V4.02 bootloader and the V5.06 application firmware. New application firmware is frequently released, and can be upgraded without needing a programmer using the IOIODude application. Additionally, this version of the IOIO-OTG has corrected the IC power failure issue due to the on-board switch voltage regulator failing as well as adding a missing decoupling cap on the AVIN pin. This new IOIO-OTG has fixed the problems that plagued the previous version making it a true vision of how the board is intended! You can find out more about these updates here.

The board includes a JST connector for attaching a LiPo battery and there are several pin headers broken out for voltage and ground access. A trimpot on the board allows you to adjust the charge current used when the IOIO-OTG is acting as a host. A USB-A to micro-A OTG cable is included which will let you connect your android device to the micro-USB port on the board using the cable that came with your android device.

你是一個Java開發人員希望我先進的硬件/ O功能添加到您的Android或PC應用程序？好吧那麼IOIO-OTG是為你！該IOIO-OTG（發音為“溜溜球-OTG”）是一個開發板專門設計來做到這一點。酒店設有一個PIC單片機，其作用就像你的電腦或Android設備到低級別的外設，如GPIO，PWM，ADC連接上的一個應用程序的橋樑，I ² C，SPI和UART。一個應用程序級庫可以幫助你編寫代碼控制這些低水平的外設以同樣的方式，你會寫其他的Java應用程序！

什麼從以前的IOIO板分隔IOIO-OTG是利用USB的On-The-去規範連接作為主機或配件的能力。有幾種方法到IOIO連接到您的Java應用程序。如果應用程序在Android設備上運行時，IOIO-OTG將作為USB主機和電源充電電流到您的設備（意味著IOIO-OTG將需要自己的電源）。如果您的應用在Windows，Linux或OSX機器上運行時，IOIO-OTG將承擔設備模式並提出自己作為一個虛擬串口。在設備模式時，IOIO-OTG可以由主機供電！連接USB藍牙適配器將導致IOIO-OTG以顯示為藍牙串行連接，所以你可以去無線！

電路板上的開關可用於向IOIO-OTG強行進入主機模式，但大部分時間可在“自動”模式下離開了董事會，它會檢測其在連接作用。現在我們正在出貨IOIO-OTG板上裝有V4.02引導程序和V5.06應用固件。新應用固件經常釋放，並且可以無需使用IOIODude應用程序員進行升級。此外，這個版本的IOIO-OTG已經糾正了IC停電的問題，由於板載開關穩壓器故障以及添加AVIN引腳上缺少的去耦電容。這種新的IOIO-OTG有固定困擾以前的版本使它的板打算如何真正的視力問題！你可以找到更多關於這些更新這裡。

該板包括用於連接鋰聚合物電池JST連接器，並有爆發的電壓和地訪問幾個腳頭。電路板上的可調電位允許您調整當IOIO-OTG充當主機所使用的充電電流。一個USB-A到微型A OTG線包括可以讓你使用你的Android設備附帶的線纜將Android設備連接到micro-USB接口的主板。
