4. Frequently Asked Questions
? Can I program the BITalino?
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.
?
What is the battery lifetime?
The BITalino Mini can last up to 5h acquiring with its standard battery (240 mAh),
although BITalino is compatible with any JST PHR-2 terminated 3.7V battery enabling
you to easily extend the lifetime.
?
Can I communicate with the BITalino using other interfaces besides bluetooth?
Yes. BITalino has the UART port fully exposed, which means that you can replace the
Bluetooth interface by any UART-
c m b v c ( g Z g , W F y, F D , …)
Furthermore, by programming your own firmware, you can also make use of the SPI
port.
? Are the BITalino accessories compatible with other devices?
BITalino accessories can be connected to any third-party devices that can provide a 0-
3.3 V 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 use the BITalino blocks that are available in our webstore as
individual components or use our BITalino (r)evolution mini. Alternatively, if you think
your project needs a partner and R&D collaboration you can always ask for our services

?
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.
? Can I use the BITalino while charging its battery?
No. The BITalino was designed to charge only when turned off. For your safety, you
should not attempt to use it with a charger plugged.
? 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.
