|What is BITalino?||BITalino is a hardware and software toolkit that has been specifically designed to deal with the requirements of body signals.|
|What is the difference between BITalino (r)evolution and BITalino?||BITalino (r)evolution is our all-new next generation platform with almost 2x the blocks and up to 60% smaller sensors… check out the our comparison table at: http://bitalino.com/index.php/buy/product-finder>|
|Board, Freestyle, and Plugged… what’s the difference?||The Board is an all-in-on and ready to use kit with all the blocks pre-connected. The Freestyle is the same as the Board, however each of the pre-connected pieces have been separated, which allows you to solder all the components together and create your own custom-made wearable. The Plugged is the same as the Board, but in addition has a pluggable cabled connection between the sensors and the main board providing maximum versatility to Bitalino or third party boards such as Arduino.|
|For basic data visualizationa and recording using a kit is it necessary to do any hardware or software programming?||No... all BITalino kits and MCU are ready to use out-of-the-box. The default firmware is pre-programmed to perform real-time data streaming, and our easy-to-use OpenSignals software enables the full control of the device and online & offline data visualization.|
|Is there any software available?||Besides the hardware, BITalino also includes a Python-powered web-based free software framework called OpenSignals for rapid application development, and a growing number of programming APIs. OpenSignals makes is very easy to extract and visualize the signals from the sensors. No algorithm processing is built-in into the base OpenSignals so currently you should use your own programming language such as Python or third-party tool such as Matlab to do the algorithm processing on the signals you may want to do for your application.|
|Can I program the BITalino MCU?||Yes. You can write your code in C, and upload it to the micro-controller using an AVR ISP programmer; you can also upload the Arduino bootloader onto the board. Nonetheless, given that all the sensors and peripheral on BITalino are general-purpose, it may be easier to replace the BITalino MCU by an Arduino or another 3rd party system.|
|Are the sensors pre-connected in the BITalino Board?||Yes. All of the sensors are pre-connected to the analog inputs on the MCU block and ready to use; even the LED is also pre-connected by default to one of the digital inputs on the MCU block.|
|Is it possible to acquire data from all channels simultaneously?||Yes. BITalino enables the synchronous and simultaneous acquisition of up to 6 analog and 4 digital inputs.|
|What is the battery lifetime?||~10h with the standard battery, although BITalino is compatible with any JST PHR-2 terminated 3.7V battery enabling you to easily extend the lifetime.|
|Can I use other interfaces besides Bluetooth?||Yes. BITalino has the UART port fully exposed, which means that you can replace the Blueooth interface by any UART-compatible device (e.g. ZigBee, WiFly, FTDI, …).|
|Are the BITalino accessories compatible with other devices?||BITalino accessories can be connected to any third-party devices that can provide a 0-3.3V power supply and that can deal with the analog outputs of the sensors.|
|Can I connect third-party sensors to BITalino?||Provided that your accessories have power and analog output specifications compatible with those of the BITalino hardware you can connect any sensor and even your own custom designs. You can also connect 1-bit digital input or output accessories (e.g. switch).|
|Can I create a wearable device for body signal monitoring?||Yes. You can either snap off the BITalino blocks or use a Freestyle kit and solder all different components in a format to your preference; the main blocks such as the MCU, Bluetooth, and Power were designed with matching pins that enable them to be stacked.|
|Why do the output values from BITalino range from 0 to 1023?||0-1023 are the digital codes produced by the analog-to-digital converter; these can be converted to the correct physical units using the right transfer function for the sensor that produced the data.|
|Is the sampling rate (e.g. 1KHz) per channel or shared between the acquired channels?||The sampling rate on BITalino is per channel and not shared. For example, if the acquisition is performed at 1KHz (or any of the other options for what matters), each channel is sampled at the chosen rate regardless of the number of channels acquired.|
|Can the sampling rate be independently set for each channel?||In order to improve the ease-of-use of the software and APIs, we chose to have all the channels sampled at the same sampling rate.|
|Does OpenSignals record data from third-party sensors?||Given that both the BITalino firmware and the OpenSignals software are general purpose, data from any sensor with compatible electrical specifications that you connect to BITalino can be recorded using OpenSignals.|
|Does the MCU make any type of filtering or signal conditioning?||No. The only signal conditioning done at the hardware level is made on the analog front end of each sensor... all the inputs & outputs on the MCU are general purpose and unconditioned.|
